Instructions for use of SR-602 pyroelectric human body infrared sensor module
Features and uses:
This module has high sensitivity, fast response speed, small static power, small size, easy to install, lenses, soldered pins, and power supply, no debugging is required.It can be used for human body sensing lights, alarms, security, access control on-demand cameras, agricultural, forestry and mining automatic equipment, etc.
Key points:
1: The high-level time of output of this product is adjustable, 2.5 seconds to 1 hour, and the output time set at the factory is 2.5 seconds. If you need to change, you can change a chip resistor. Please refer to the relevant table below for the resistor value corresponding to the typical delay time.
2: Blockade time, 2 seconds,Established.
3: Factory defined as repeatable triggering.Cannot be changed.
4: The power supply voltage of this module is 3.3V-15V, and the limit voltage is 2.8V-18V.
5::The output timing of the module is: after power-on, the output of high level is 2 seconds, then it becomes low and enters standby state. If the delay time is changed, the time when the module outputs high level will increase accordingly after power-on, which can be understood as the startup time when entering the normal working state after power-on will increase.
6::After installing the photosensitive element, it does not work during the day, works at night, does not install photosensitive elements, and works throughout the day (default is that there is no photosensitive element installed)
7: This module is very sensitive, pay attention to the installation location, and try to avoid heat source radiation (air outlet/direct sunlight)
8: The sensitivity of this module is adjustable, and a chip resistor needs to be changed.
9: When using 220V ordinary Luo iron welding, you need to unplug the power supply before welding. It is recommended to use 24V low-voltage soldering iron.
