- This module has high sensitivity, fast response.
- The Sensing distance is up to 5 meters; recommended 0-3.5M.
- Small static power consumption, small size, easy to install.
- This module is very sensitive, pay attention to the installation position, try to avoid the heat source radiation source (air outlet / direct sunlight).
- It can be used for human body induction lamps, alarms, security, agriculture and forestry mining automatic equipment, etc.
Pyroelectric Infrared Sensor Module
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
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.
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 standby status. If the delay time changes, the time that the module outputs a high level after power-on will increase accordingly. This can be understood as the state in which the module enters the normal working time after power-on is prolonged.
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.) 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.
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.
