Motion detector SR602 MINI Motion Sensor Detector Module

Overview:
This motion detector 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 downward-facing pins.
However, detailed changes, e.g. to the sensitivity, are more complex and are made by soldering on 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 the power supply 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 standard state. This time can be changed by soldering on resistors. However, this is rarely advantageous for use with Arduino.
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 takes place according to the following scheme: output a high level 2 seconds after switching on, then go low and switch to standby mode. 
This module is very sensitive, pay attention to the installation position, avoid the radiation source of the heat source (air outlet / direct sunlight)
The sensitivity can also be changed via a resistor (table).
