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 ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

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 ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

Using the latest Raspberry Pi 4 Model B mini PC, you can easily create a sophisticated security camera system complete with a motion sensor. This setup will automatically send images taken using a ...

The Arduino is a cheap electronics board that allows you to make your own electronics without a ton of coding experience. We love the Arduino, but like any electronics project, coming up with ideas ...
