Description of product

Description

MOTION click is a motion detector sensitive only to live bodies. It carries PIR500B, a pyroelectric sensor. The click is designed to run on 3.3V power supply only. It communicates with the target MCU over RST and INT pin on the mikroBUS™ line.

How it works

MOTION click carries PIR500B, a pyroelectric sensor which generates a voltage when exposed to infrared radiation emitted by live bodies (the white plastic Fresnel lens covering the sensor filters visible light).

The signal is processed by a BISS0001 PIR sensor controller which sends an interrupt to the MCU through the mikroBUS INT (out) line.

An onboard potentiometer lets you adjust the detecting range of the sensor (up to 4 meters).

Night only mode

The click also has a night only mode—resoldering a zero-ohm jumper activates the onboard photo resistor which acts as a light-sensitive switch.

You can also switch the sensor ON and OFF by sending a signal from the MCU through the mikroBUS RST pin.

Application

MOTION click is ideal for alarm systems, light switch controllers, and similar systems where human presence needs to be detected.
