The M5 Stack PIR motion detector is used to infrared light (IR) to measure the objects in his field of vision is transmitted. PIR sensors are usually used simply as "PIR" or sometimes referred to as the "PID" for "passive infrared detector". The term passive refers to the fact that PIR devices do not emit infrared radiation energy for detection purposes, but only the objects that are transmitted or reflected. This device communicates with the M5-core via the Grove. g. Note: This equipment has a delay time of 2 seconds. This text is machine translated.
