M5Stack PIR Motion Sensor (U004) – motion detector (AS312)

A classic PIR motion sensor: it reacts when a warm body moves in front of it. Perfect for the hallway, the stairs or the storage room: light on when someone comes, off when it's empty.

Good to know

A PIR sees motion, not presence. If you sit completely still on the sofa it stops reacting. If you need to detect people sitting still, choose the TMOS PIR (U185).

Works with

• ESPHome (binary_sensor with the gpio platform)
• Home Assistant via ESPHome
• All M5Stack controllers with a Grove port

You also need

A controller, for example the AtomS3 Lite. Grove cable included.
