Staying on top of the emerging trend and technologies behind the "Internet of Things"

Hey everyone!

I’m starting a program in Internet of Things and Machine Intelligence, and the college recommends using a Windows-based laptop. However, I already have a MacBook Pro M2 and would prefer not to switch to Windows.

The courses include topics like networking, data analytics, programming, embedded systems, AI applications, and robotics. Some instructors and IT support might only provide guidance for Windows systems, but the software itself seems to have Mac-compatible options.

Has anyone taken a similar program or used a Mac for this kind of coursework? Did you encounter major challenges, or is it manageable?

Thanks in advance! 😊

Hi all

Does anyone have any documentation for the US requirements on communication modules? I get the impression that SIMCOM A7672G will work in America, and is FCC approved, but can't be used as it uses a Chinese chipset?

I can use the SIM7672G instead, which uses a Qualcomm chipset, but that would involve a full softwear rewrite. If I can I would prefer to stick to the A7672G, but I just need evidence that I either can or can't do this.

Basically I’ve learned that a major contributor to eye strain and dry eye disease, which I am struggling with, is the way our blink rates drop when using screens or reading ect. I am looking for a solution to train myself to blink appropriate times per minute but trying to do it without an automatic reminder doesn’t fully work plus it breaks concentration a lot. Any ideas of tools I could use. Thank you!

Ps. i’m mot tech savvy ag all😓

I am starting to consider 5g sim router as backup for my whole internet. For example if the main ISP has issues then all the ecosystem keeps going.

Devices are the ones you typically expect: smart doorbell, WiFi CCTV uploading motions to cloud (ring or reolink blink type), TV to stream a show or phones and computers to browse / work.

The bandwidth comes from the ISP and goes to switch. From there there is a Deco mesh for WiFI connections, but also hard wired ethernet going through some devices around the house via power line.

The Deco app (the mesh) tells each device connected to the mesh's consumption (up and downstream) live but not over say a day or a week.

Likewise I can install software on my pc to find out how much bandwidth is used by the pc but that only works for that pc

My thinking is if everything goes via the switch, monitoring the switch would be a start. However I still have issues to monitor WiFi devices. For example how much upload did a ring cwmera use to send all the motions to the cloud?

I'm early stage in the thinking and may be missing something obvious. How would you go about monitoring each device bandwidth consumption to precisely assess needs?

Hi everyone,

I’m a student considering a graduation project to expand goal-line technology (e.g., Hawk-Eye or magnetic field systems like GoalRef) to monitor a larger area and send real-time alerts when boundaries are crossed.

As a beginner in IoT, I’m unsure how complex this would be. Is this manageable, and which system (magnetic fields vs. cameras) would be more practical?

Would love any advice or suggestions!

Thanks!

I am a complete beginner in anything hardware. I'm a software developer. My company however is asking me to build a wearable camera. They're willing to get me any components I need. It should have a camera on the front and a camera on the back. It needs to combine these two videos into a single 350 deg video and stream stream this feed to a server.

I did some research on cameras and micro controllers. I have a few questions:

1. What protocol should I use for streaming the video?

1.1. Internally from the camera to the processor 1.2. Over the internet. From the processor to a server. (I noticed that a lot of camera systems use RTSP to stream video. It's that a good idea for this use case?)

2. If I use 2 fisheye cameras, will it be possible to stitch them together on the processor before streaming to a server

3. What processor should I use for prototyping? Raspberry pi, Arduino or anything else like that (I am very new to all this)

We might need to add more processing functionality in the future. Something like basic object detection that runs in the same processor.

I'm thinking of adding some remote control to a couple of gates in the property (opening, closing and checking the state, basically) and I was wondering if anyone could help me get started in the right direction on what kind of devices I could use to do that.

The gates already have eletric motors and remote controls but I want to be able to control them and see their state remotely not just from a few meters away...

I'm ok with general electronics and I've also played with arduinos and raspberrys so a more DIY solution would be ok. My doubts are more towards the connectivity of the devices to the network/web.

I've never done much IOT itself so I don't know what's being used nowadays...

Hello, I’ve come to ask for help with a university project involving the use of a wristband for beaches, to improve the safety of children and bathers. The idea is that the bracelet allows communication with personal cell phones or a server, transmitting data such as location, sensor signals (accelerometer, gyroscope, heart rate, etc.) and notifications to the parent if the children leaves a predefined safety area.

My questions are: 

• Are there any ready-made wristbands or devices on the market that could be adapted for this purpose? I'm open to solutions that can be reprogrammed or modified.

• If I need to develop from scratch, which components would be best? I thought about using LTE and BLE for communications with the server and the parent cell phone respectively, but I have no experience with these technologies. What do you recommend in terms of modules, sensors and microcontrollers?

• What would be the most efficient approach to ensure real-time communication, considering the beach environment, which can have unstable cell phone signals?

And do you see any critical points and what practical issues should I consider, such as battery life, durability in environments with sand and water, or integration with mobile apps?

Am I crazy or does it seem like we need some type of random generation of IoT creds upon use by the customer? Simply using root/admin doesn't seem to work anymore but to just change the entire use of default credentials.

Are there any projects or movements out there to eliminate the repetitive use of the same default creds in consumer products?

Let me know if I'm crazy, thanks.

I have been researching IoT solutions for my projects, and I have found some of the best and have collected them in this list. Each of them have pretty generous free tiers, and one is open source. They are in no particular order, and I suggest you look at them to see if they fit your needs.

1. Blynk
2. Arduino IoT Cloud
3. Thingsboard
4. Particle

There is no brand affiliation nor any promotion of any of these in a sponsored way. These are just what I have found as good platforms for my projects.

I have seen several publications of early fault detection using FFT, is it currently implemented in the industry?

Hello, i wanted to ask if anyone knows if programmable/interface-able light sockets exist? Like a sort of adapter between the actual socket and a bulb.

I know you can get whole light bulbs in that fashion but i really don’t want to depend on the respective company’s software interface, and i want to be able to swap light bulbs as per my wish.

Thanks in advance!

Hello. I am currently researching career changes but a red line for me is being on call . IoT sounds like an interesting avenue to explore but I would need to know if on call duties are common in IoT jobs? any info on this would be appreciated.Thanks

This is an automatically moving chessboard: https://miko.ai/products/miko-chess

I know how to code web elements, work with chess API and maybe even use raspberry pi, but if someone who knows better than me can tell me roughly how to make this would be much appreciated.

Making a small board for myself since it's fun + I started learning chess so it will be easier.

Hello, we are learning about IoT in school and we need to plan an architecture for a smart city in theory. I found four sensors that measure the things we need and I want to use an ESP32 for all parts of the architecture. I guess I need another Module to use LoRaWAN and then MQTT at the gateway. In the picture you can see my current plan for the architecture. Do you guys think my plan makes sense? Thanks for the help :)

Overview of the Azure cloud architecture used in the study

The framework aims to integrate precision medicine into clinical practice by understanding provider-patient interactions, disease model complexities, and healthcare system design. It focuses on creating a virtual replica of the Critical Care Unit (CCU) to organize physical twins using a digital overlay.

• We used Azure services such as Azure IoT Hub, Azure IoT DPS, Azure Digital Twins, Event Grids, and Function App.
• We automated resource allocation such as device provisioning and symmetric key generation using the Azure Resource Manager SDK.
• We used C# and .NET 8 to implement the DT4CCU framework.

For more details on the implementation, check out the paper at ResearchGate and Research Square!

Fundamentally speaking it seems IOT is focused on sending data from a device over TCP to something that gathers the data. Yes I know this is a broad brush I’m using but I’m not far off.

When I look for examples I see mainly devices sending data to a local server (eg raspberry pi or such). If they send data to the “cloud” typically they use a service that exists for DIY projects. An example would be Adafruit IO.

I have an account on a server. What I would like to do is send data to “something” on that server that I have created to display and store on my own website. The problem is I don’t see anyone doing this. I can’t find discussions of it. I’m sure it’s out there. I can’t be the only one.

Does none know where I can go to learn? See examples? Is it just too hard for the hobbyist?

Is it possible to have a dimmable battery powered led strip.

I have seen this battery powered led strip - https://amzn.eu/d/8pjgWAP

How would you recommend making this WiFi controllable?

Hi, I have a small iot business, I have completed dozens of installations all working fine but I need to really drill down into JS, so I can upload info. All of the courses I see are either about the transmission side of IoT or if JS they are Web design. Before you ask bout running a company without full JS knowledge, my kit goes on hire for only a few weeks at a time.

How to get USB of Pi Pico working in USB Host mode? Need to connect a USB QR code scanner and send the payload over rest API. Is newest firmware supportive of the activity by default?

Hi guys,

I’m trying to create a publisher using AMQP with an iOS app. The only app I’ve found so far is AMQPClient, but it doesn’t seem to be working for me.

Does anyone have suggestions for alternative apps or tools that work well for AMQP on iOS? Or perhaps some tips on configuring AMQPClient properly?

Any help would be greatly appreciated. Thanks in advance!

I am first year student of IOT branch persuing my b tech from NIT kurukshetra, being new to this subject i needed some guidance on how to start and grow in this field. Being a newbie i know nothing about it and i am feeling lost in life rn due to personal issues, can someone please guide me, where to get resources from and where to start from. You help would be really appreciated, tysm <3

I have multiple nodes with ESP32 with different sensors each and a mobile application for visualization of data. Currently, I know that IoT system relies on a connection to a central cloud platform to exchange data over the Internet. But, I'm tasked to make this system decentralized, in which they brought up about blockchain so basically they wanted to make the system similar to the concept of blockchain. However, I'm thinking that blockchain would be tedious as it is new to me as well.

How do you think this kind of system be "decentralized" or if you think blockchain is a good idea, do you have some references I could look into for this kind of system?

I'm looking to get something like a pendant or a bracelet with a single button, that when pressed would send out a notification or a call to pre programmed contacts. I've seen something like this, but they are only available in some regions and usually come with subscriptions and their own call centers that handle those emergencies.
What I would assume I would need is a button that can be programmed to send out a signal to some base station that then could be programmed to send messages or calls. This device would be for my grandmother, she's alright but I'm being preemptive, she walks her dog daily so the system would need to have some range to it. I'm not sure what type of signal could carry good enough range, maybe like loRa or something like that?
And for base station, what would I need? Something like an arduino or even raspberry pi?
Any suggestions would be nice. I'm not too experienced with stuff like this, maybe some of you have made a system that would work in such a way?

I'm concerned that an RFID-only attendance system could be misused if a student scans multiple RFID cards to mark attendance for absent friends. To address this, I thought of incorporating IR proximity sensors on each table (each table has two seats). Each sensor would be directed at a seat to verify that the number of occupied seats matches the number of scans recorded by the RFID reader. However, I'm unsure if this approach would be robust enough. My goal is to avoid using cameras to minimize sensitive data transmission and enhance the smart table functionality.

What suggestions do you have for improving an RFID-only attendance system?

also, im planning to make this system decentralized, not yet sure how xx

In powering a mini dc pump, im concerned that a 5v relay module is not enough with the other sensors in used. Im opting in using a buck converter if this is okay. Anyways, this is my first time with iot, this is our final project and it would be presented this coming 25. I never started to code yet its because we still need to clarify its function
