Joy-it SBC-PIR Motion sensor 1 pc(s) Compatible with (development kits): Arduino, Raspberry Pi®, BBC micro:bit

The sensor on this module is
a pyroelectric infrared sensor,
which
detects a movement in the detection area of the Fresnel lens
and

then outputs a "HIGH" signal at the sensor output pin "SIG" for 3 seconds.
Then the signal returns
to the "LOW" state. The soldered potentiometer is used for
infinitely variable range adjustment.
With the help of this module and
a microcontroller such


as Raspberry Pi or Arduino, it can be used for security systems or automation, among other things.
