When the pyroelectric infrared signal received by the MINI SMD Four Element Anti Jamming Digital Pyroelectric Infrared Sensor exceeds the trigger threshold inside the probe, a counting pulse is generated internally. When the probe receives such a signal again, it will think that it has received the second pulse. Once it receives 2 pulses within 4 seconds, the probe will generate an alarm signal and the REL pin will have a high level trigger.
