Dear user, we are sorry for your inconvenience. When warm objects like people or animals pass by the detection area of the PIR motion sensor, the IR signal detected by the pyroelectric probe changes. The sensor then reports the change to App. The detailed reporting process is as follows:

The PIR motion sensor reports its status to App after successful net pairing.
When the sensor detects a possible human motion (an IR signal change), it sends a ''Motion Detected'' notice to App, turns on a 50-second timer, and enters the sleep state (it stops detecting motion within the 50-second sleep period).
If the sensor detects an IR signal change within 10 seconds after waking up from the sleep state, it enters another sleep-wake up cycle without reporting to App. If the sensor detects no IR signal change within 10 seconds after waking up from the sleep state, it sends a ''No Motion'' notice to App.
The automation-trigger condition-no motion interaction mechanism takes effect if App does not receive a ''Motion Detected'' notice after the sensor has sent the ''No Motion'' notice to App and the service is activated at the backend.
