Compact PIR sensor with control board and TTL output (high level 3.3 V - Low 0V).
It has two modes of triggers, a delay time from 0.3 to 180 seconds, consumption of 65μA on standby, a detection angle of 120 ° and a maximum range of 7 meters. It has only three pins (output , positive and negative power supply).

Trigger mode:
A. Mode not repeatable: when the sensor detects motion, the output goes high (3.3V TTL) , after the delay time set , the output automatically reverts from high to low.
B. Mode repeatable: when the sensor detects motion, the output goes high (3.3V TTL) and remains in this state as long as the sensor detects motion .
