In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. You’ve probably seen them—sensors watching from the corners of ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...
