STM32F1 blue pill EByte LoRa E32 E22 E220 shield v1.0
Mischianti Aug 12,2022
Full documentation of the PCBEByte E32 tutorialEByte E22 tutorialEByte E220 tutorialI start using STM32 microcontrollers, and I find they a superior quality. But I need some prototyping board to do my work faster.So here is a prototype board to develop the LoRa application. As usual, I use EByte modules, and this board is fully compatible with E32, E22, and E220.More information, BOM, and description on the relative article on the site.STM32F1 pinoutAs you can see in the pinout diagram, you can ...

Real-time Smoke Detection with AI-based Sensor Fusion
Aug 12,2022
AttentionThe following project is just a DIY project and did not replace certified smoke detectors. As I'm a voluntary firefighter, please keep your home safe and use high-quality certified smoke detectors. The sensor system which is developed by this project is only an addition.BackgroundSmoke detectors save a lot of lives. For example, the number of fire victims fell by more than 48% in France from 1982 to 2012 and 56% in the UK from 1982 to 2013. These reductions can largely be linked to incr...

DIY Handheld Thermometer with WiFi
SimonX Aug 04,2022
BackgroundNow is 2022 and we are still combatting COVID and its varients, it's a long battle so we need to play it smart.How smart? There are many off-shell handheld thermometer out there and they offer very simple functions yet sell it quite expensively, but with the right tool and a bit of DIY spirit, you can actually make one that has IoT capability at lower price. What is this about?The main idea is to use an Arduino compatible dev board with WiFi connectivity to read temperature from a...

STM32 LoRa Wireless PIR Motion Sensor
Useful Electronics Jul 31,2022
https://youtu.be/aKUESTVg_8AIn this tutorial, A simple wireless PIR motion sensor is designed and build over LoRa. the project includes 2 board with to STM32 MCUs. One of them is interfacing a PIR sensor and the other one emulates siren sound using a buzzer. Two MCUs are communicating witlessly over LoRaGitHub Repository: https://github.com/UsefulElectronics/stm32-rylr998-lora-transceiver

Senso (Identification of Ilegal Logging)
Andrei Florian Jul 30,2022
AbstractFigure 1: The Senso device attached to a treePeople are always told to recycle and turn off the tap while they’re brushing their teeth, however, little is said to us when it comes to preventing the active termination of our oxygen supply. Even as we are wavering on the precipice of disaster, there are still those who unlawfully endanger the rest of humanity through their wrongdoing. Illegal logging is a major threat to the world’s forests, and to the biodiversity and the people they...

?? Save The ElephantsLet's work together and save the beautiful elephants using cutting edge technologies around us.?? On Going CrisisAccurate estimates suggest that there were 12 million elephants in the early 1900s. Today there are only 350, 000, which includes both savanna elephants and forest elephants.That’s a 97% decline in just one century. At current mortality rate this species will extinct by 2030 !Botswana is the largest home for African elephants (130, 000) followed by Zimbabwe.P...

Touchless ATM using Augmented Reality
mithundotdas Jul 29,2022
Stop The SpreadPrevent spreading of COVID-19 is very critical to flatten the curve. Research has found that COVID-19 virus can transmit through public objects used by many people in similar fashion during the course of a day such as ATM keypad, Gas station keypad, self checkout at grocery stores. Sanitizing keypad after every use is simply not feasible.So we need a technology which can help us operate the keypad without physically touching it. At the same time we need to consider cost of new sys...

SmartWay (Geolocation Monitoring)
Andrei Florian Jul 29,2022
AbstractFigure 1: The SmartWay device attached to the child's bag is glowing orange (meaning they have arrived late) According to the European Commission, every two minutes, a child is reported missing in Europe; and as of 2020 in the US, 2,300 children are reported missing per day.?While 99% of missing children return home alive, these shocking statistics will discourage any parent from letting their child go to school or anywhere else alone. SmartWay is my solution to this problem; I...

Machine Vision Trip WIre | Switch App when Motion Detected
SimonX Jul 28,2022
IntroductionWanna slack off abit but scared to be busted? Here is the all-in-one wireless tripwire that help you automatically switch your computor program when motion is detected! Best of all, it uses MicroPython to program OpenMV so you can even add some "whitelist" using face recognition, and it also use RTL8722DM_MINI as the Bluetooth Keyboard, so you can even trigger a custom script upon motion detected~??DemoProject DetailsA hearty combination of "Machine Vision" and "Bluetooth HID" functi...
