SR602 MINI Motion Sensor Detector Module

Overview:
This motion sensor is a newer and more compact version of the so called PIR sensor (motion detector). 
The sensor has the advantage that it can be mounted on breadboards due to the pins pointing downwards.
However, detailed changes, e.g. to the sensitivity are more complex and are done by soldering resistors.
This module has high sensitivity, fast response, low static power consumption, small size, and is easy to install.
The lens and pin head have been soldered, and power is provided without troubleshooting. Can be used for body sensor lights, alarms, security, access control.
The high level time of the output of this product is adjustable, the factory set output time is 2.5 seconds to 1 hour.
The time is about 3 seconds in the default state. By soldering resistors, this time can be changed. However, for use with Arduino, this has little advantage in most cases.
The supply voltage of this module is 3.3 V to 15 V and the limit voltage is 2.8 V to 18 V.
The output of a sensor value is as follows: output a high level 2 seconds after power on, then go low and go into standby mode. 
This module is very sensitive, pay attention to the installation position, avoid the radiation source of the heat source (air leakage / direct sunlight)
The sensitivity can also be changed by a resistor (table).
