Motion-Activated LED Lighting Automation
Lights that turn on when someone walks in and off after a timer, using a PIR sensor and a relay or MOSFET.
About this project
A PIR sensor detects movement and the controller turns on lighting for a set time. A light sensor can be added so it only switches on in the dark. Simple, useful and easy to demonstrate.
What it does
- PIR motion detection
- Adjustable timer
- Optional darkness sensing with an LDR
- Relay or MOSFET output
Components needed
- Arduino Nano (CH340)
- 5V Relay Module (1 channel)
- IRLZ44N Logic-Level MOSFET
