What is the output of a PIR sensor?

Output: Digital pulse high (3V) when triggered (motion detected) digital low when idle (no motion detected). Pulse lengths are determined by resistors and capacitors on the PCB and differ from sensor to sensor.

What is sensitivity in PIR sensor?

PIR Sensor Components  Sensitivity Adjust knob: The sensitivity adjust knob determines the distance (range) of motion detection of the sensor. It can be made to vary between 3 meters and 7 meters. The view area of the sensors is typically 110 degrees.

What is the size of PIR sensor?

Length: 24.03mm/0.94in. Width: 32.34mm/1.27in.

What is a PIR sensor module?

The PIR Motion sensor module is an automatic control module based on infrared technology. It adopts LHI788 probe, which has high sensitivity, high reliability, low voltage working mode and low power consumption. It can be widely used in various types of automatic induction electrical equipment.

What is L and H in PIR sensor?

L position is for toggle LED, not much use in practical , In H position the LED will stay high when motion else Low.

How do you test PIR?

Cross check the circuit wiring to ensure it is properly done, and then turn on the power supply to test the PIR motion sensor. Wait for the PIR sensor to calibrate properly, this will normally take from 10 to 60 seconds. If the LED is on, please wait until the LED turns off.
