The PIR Sensor has infrared detection and light intensity measurement functions. It has two modes, which are linked light control and security alarm.

In the linked light control mode, when the detected infrared data and light intensity data meet the set value at the same time, it automatically sends a control command to turn on and off the light to the designated controller.

In the security alarm mode, when human movement is detected in the armed state, alarm intrusion information is sent to the mobile phone in real time to avoid unnecessary losses.
