This model features high sensitivity, fast response, low standby power consumption, small size and easy installation. The lens and pin head are already soldered, and the power supply is provided without any problems.

It can be used for body sensor lighting, alarms, security, access control. The high level time of this product's output is adjustable, with a factory preset output time from 2.5 seconds to 1 hour.

The default time is about 3 seconds. This time can be changed by soldering resistors, although this is rarely useful for use with Arduino.

The model's supply voltage is from 3.3V to 15V and the voltage limit is from 2.8V to 18V.

The sensor output is as follows: it produces a high level 2 seconds after power-on, then goes to a low level and enters standby mode.

This model is very sensitive, so pay attention to the installation location, avoiding heat sources (e.g. air ducts or direct sunlight). The sensitivity can also be changed via a resistor (panel).
