M5StickC PIR Motion Detector HAT AS312

The M5Stack PIR HAT is a passive infrared motion detector that plugs onto the M5StickC. It detects the heat radiation of people and animals. When motion is detected, the output on G36 goes HIGH and stays HIGH for about 2 seconds; it can be retriggered during this time.

Features:

• AS312 PIR sensor
• Output on G36, HIGH on motion, hold time about 2 s
• Low quiescent current below 60 µA

Application Examples:

• Motion detector and presence detection with the M5StickC
• Triggering light or alarm on motion

Documentation:

• M5Stack documentation with pinout and examples
• Arduino example code (M5Stack, GitHub)
