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. |
