[ChrisJ7903] has created two Ardiuno programs for reading Victron solar controller telemetry data advertised via BLE. If you’re interested in what it takes to use an ESP32 to sniff Bluetooth Low ...

For smart home deployments, there are a lot of ways to track the presence of individuals in a room. There are motion detection sensors that use mmWave and PIR, and you can also use simple detection ...

I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

ESP32 GPIO Bridge transforms an ESP32 development board into a versatile, PC-controlled hardware interface. It allows a host computer running Python to directly control and communicate with hardware ...

This beautiful little radio may look like an art deco relic from a hundred years ago, but it is actually from 2023. When [Craig Lindley] first saw this design on these very pages a few years ago, he ...

This project uses an ESP32 microcontroller to read environmental data from DHT11 (temperature and humidity) and MQ135 (air quality) sensors. The collected data is then transmitted over Wi-Fi and ...

Soon to be launching via Crowd Supply is a powerful ESP32 based IR/RF remote taking the form of the aptly named ESP360 Remote. The small open source hackable IR and RF remote features 9 IR LEDs and an ...
