About Monitoring Principles
1. The sensor uses infrared background radiation as the inspection principle
2. During installation, it is necessary to avoid direct sunlight and other heat sources, as they may interfere with the inspection results.
3. It can only check the changes in background radiation and cannot monitor the movement of background radiation
4. In order to avoid duplicate alarms, we made logical judgments internally:
–a. If the previous state is “no one state”, upon detecting someone, immediately report an alarm and set the state to “Human status”. At the same time, turn on the 30 second “Human status countdown” timer, and do not check again before the timer ends.
–b. If “Human status countdown” timer stop ,if there is still someone present, restart “Human status countdown” timer for 30 seconds.
–c. If “Human status countdown” timer stop ,If it remains no nobody for 10 seconds, the sensor sets the status to “no one state” and reports the information.
So it is incorrect to test immediately by waving your arms after the configuration is completed.
The correct testing method should be to completely leave the sensor for at least 40 seconds before reappearing within the sensor’s detection range.
