Humidity and Temperature Sensor SPD-HT485

The infrared detector PA-40D is a highly stable passive infrared detector. It employs advanced signal analysis and processing technology, featuring extremely high detection and anti-fault alarm performance. When an intruder passes through the detection area, the detector will automatically detect human activities within the area. If there is any dynamic movement, it will send an alarm signal to the control host.
