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 ...

This project defines the source code for a ESP32 based sunlight sensor. The sensor is designed to measure the intensity of light of and send the results to a web service. This is my first embedded ...

This project enables real-time distance measurement using an ultrasonic sensor (HC-SR04) and displays the measured distance on a webpage. The ESP32 microcontroller reads the data from the ultrasonic ...

Rednexing, a North Carolina based startup, is preparing to launch a Crowd Supply campaign for PowerTortoise IoT, an ESP32-based development board designed for ultra-low-power operation. Built to run ...

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 ...

Wide working range from 80 mm to infinity. No lens focusing is required during the lens mounting process. Motion data registers with 16-bit resolution Motion detection Intruupt The PMW3901 is commonly ...

The XIAO Smart IR Mate is a compact circular-shaped IR remote hub/blaster built around the XIAO ESP32-C3 and designed for IoT applications. It comes pre-flashed with ESPHome and turns traditional ...
