Feature:

1. The human body infrared sensor module has high sensitivity, fast response speed, low static power consumption, small size, with welding headers, and easy installation.

2. After the photosensitive element is installed, it does not work during the day but works at night, if it doesn't contain photosensitive components, it will work all day

Key Points:

1. The high level time of the output of this product is adjustable, 2.5 seconds to 1 hour, the output time set at the factory. It is 2.5 seconds, and you can change one chip resistor if you need to change it.Read the resistance value corresponding to the typical delay time.Please refer to the relevant form above.

2. Blocking time, 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 standbystatus. 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 ( There are no photodiodes on the module,please purchase separately if needed.)
