Product Description

Working Principle: When a person enters the detection area of the sensor, the internal thermal element will generate voltage changes due to the energy of the human body's infrared radiation. The sensor converts the voltage into a stable and reliable digital signal output, usually in the form of a high or low level to indicate whether a human body is detected
Output High Level Time is Adjustable: the default output high level time is 2.5 seconds. If you need to change it, you can change a chip resistor. Please refer to the picture for the resistor corresponding to the delay time
Output Timing: After power on, the module outputs high level for 2 seconds, then changes to low level and enters standby state. If the delay time is changed, the time it takes for the module to output high level after power on will increase accordingly. This means that the startup time for the module to enter normal working state after power on will increase
Widely Application: Smart home, such as automatic lighting control, smart door locks, etc.; security monitoring, such as intrusion detection, area monitoring, etc.; energy-saving control, such as automatic adjustment of lighting and air conditioning systems; other fields such as smart doorbells, automatic curtains, smart trash cans, etc
Note: 1. Trigger mode is triggered repeatedly and cannot be adjusted. 2. If you don't want the sensor to work during the day, you will need to solder a photosensitive element yourself. It is recommended to use a 24V low-voltage soldering iron. 3. When installing, please try to avoid heat radiation sources (air outlet/direct sunlight)
Parameters: Sensing Distance: Up to 5 meters, recommended 0-3.5M; Output: High level 3.3V, low level 0V. Power Supply: 3.3V-15V; Quiescent Current: 20μA
