If there is no further movement within the PIR operating range. PIR Sensors. The maximum sensitivity can be achieved up to 6 meters. Activation when body heat passes through the detection zones. And when PIR sensor sense any movement in targeted area of room then it gives a HIGH logic to microcontroller and then Microcontroller take place and make a call via GSM module using AT commands. One is the "Tx" timeout: how long the LED is lit after it detects movement - this is easy to adjust on Adafruit PIR's because there's a potentiometer. The sensors use passive infrared (PIR) sensing technology that reacts to changes in infrared energy (moving body heat) within the coverage area. It provides an optimised circuit that will detect motion up to 6 metres away and can be used in burglar alarms and access control systems. 6mm ø 93mm ø. This is a Pyroelectric Infrared PIR Motion Sensor Module that can be applied to security products, prototype projects or toys. Arduino - delay () function. Interior follower is automatically delayed for any activated entry/exit sensor (unless panel is armed with no entry delay). At night, the built in passive infrared (PIR) motion sensor turns on the connected lighting system when it detects motion in its coverage area.
