Description

This keyestudio PIR motion module is fully compatible with micro:bit control board.

It is mainly composed of a digital pyroelectric infrared sensor, which is a digital signal output device.

This sensor has built-in filters, strong anti-interference, low voltage and micro power consumption.

The detection distance of the module is 3-5 meters.

The detection angle in the horizontal direction is less than 80°; the detection angle in the vertical direction is less than 55° 

There are total 6 rings on the module. Note that two G rings, two V rings and two S rings are separately connected. G for ground; V for 3V; S for signal pin(0 1 2).

When using, connect the module to micro:bit control board using Crocodile clip line.

Once detecting someone moving nearby, the signal pin of micro:bit main board will input HIGH level; LED on the module lights.
