Mini MH-SR602 SR602 PIR Infrared Motion Sensor Detector Module

Description

Product Description
Features:
This module has high sensitivity, fast response, small static power consumption, small size, easy to install. It can be used for human body induction lamps, alarms, security, access control on-demand imaging, agriculture and forestry mining automatic equipment, etc.
Specifications:
Pyroelectric human body infrared sensor module, model: SR-602
Sensing distance: up to 5 meters; recommended 0-3.5M.
Output: high level, H=3.3V, L=0V
Power supply DC: 3.3V-15V
Quiescent current: 20uA
Key points:
1. The high level time of the output of this product is adjustable, 2.5 seconds to 1 hour, the default setting of output time 2.5 seconds, and you can change one chip resistor if you need to change it. Please read the following form for resistance value corresponding to the typical delay time.
2. Blocking time is 2 seconds, not adjustable.
3. The factory is defined as repeatable trigger and cannot be changed.
4. The supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.
5. Module output timing is: output high level for 2 seconds after power-on, then go low, enter standby status. If the delay time is changed, the time when the module outputs a high level after power-on will increase accordingly, which can be understood as the startup time after entering the normal working state after the electric power will increase.
6. After installing the photosensitive element, it does not work during the day, work at night, does not contain photosensitive components, and works all day. It is considered that there is no photosensitive element installed.
7. This module is very sensitive, pay attention to the installation position, try to avoid the heat source radiation source (air outlet / direct sunlight)
8. The sensitivity of this module is adjustable, and you need to change a chip resistor. Please read the relevant table below for details.
9. When soldering with 220V ordinary soldering iron, it is necessary to unplug the power supply before welding. It is recommended to use 24V low voltage soldering iron, such as domestic white light 936.
10. If you follow the MCU and connect the lamp, please read the reference circuit diagram below.
