M5Stack PIR Motion Sensor

Description

M5Stack PIR Motion Sensor is a compact PIR motion sensor module built for simple human motion detection in M5Stack and Grove-based projects. Using passive pyroelectric infrared sensing, the M5Stack PIR Motion Sensor reacts to infrared changes caused by people or warm moving objects, making the M5Stack PIR Motion Sensor a practical option for low-power triggers, room presence sensing, and motion activated lighting.

If you need a PIR motion sensor that is easy to wire and easy to program, the M5Stack PIR Motion Sensor is a strong fit. The combination of direct digital output, low standby current, and clean Grove connectivity makes the M5Stack PIR Motion Sensor suitable for human motion detection, motion activated lighting, entry alarms, and compact smart security sensor projects.
