PIR Motion Sensor LED Ceiling Light – Arduino Compatible

https://www.electronics-lab.com/pir-motion-sensor-led-ceiling-light-arduino-compatible/

This motion sensor LED ceiling light board has been designed using 4 white LEDs each of 1-3W, PIR sensor module, Atmega328 microcontroller, low ohm IRLR7843 MOSFET, and few other components. The PIR sensor detects the infra-red rays emitted by human motion within the detection area and switches on the 4 white LEDs for 10 seconds.  […]
