Quite often you forget to switch off the light or fan when going out of the room. The simple infrared sensor based power saver circuit presented here will automatically switch off electrical ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

A ESP32-Cam based project that uses a PIR sensor to trigger photo upload to a web server. The PIR motion triggers are also broadcast using MQTT. The sketch runs a local webserver making live video ...

Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

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 ...

The main principle of the circuit is to provide security using PIR sensor. This can be used in the museums to protect the valuable things and also in defense applications to detect the humans in war ...

Hi - Was hoping someone could clarify my wiring here is correct. Replaced an Arrowhead ESL2 board which has Swan Quad PIR sensors with a Paradox MG5050. Everything remained apart from the board switch ...
