MOTION click is a motion detector sensitive only to live bodies. It carries PIR500B, a pyroelectric sensor which generates a voltage when exposed to infrared light. The signal is processed by a BIS0001 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). MOTION 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. The board uses a 3.3V power supply only.
