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.

Connection Diagram
Source Code
Example Result
Connect well the module, then send the source code to the micro:bit main board.
When detecting someone moving nearby, the LED matrix on the micro:bit main board will show a heart shape icon, and led on the PIR module lights.
Or else, it will show another image and led turns off.
