Tuya Zigbee/WiFi PIR Motion Sensor Smart Home Human Body Infrared Detector Security Smart Life Works With Alex Google Home

NOTES： 1. The WiFi Version Sensor connects to WiFi 2.4GHz, and does not need a hub. 2. Creating Routes on Alexa is not supported. 3. The battery is not included in the package. 4. The WiFi version is delayed and may not be suitable for turning on lights.

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 the "Human status countdown" timer stops, if there is still someone present, restart the "Human status countdown" timer for 30 seconds. --c. If the "Human status countdown" timer stops, if it remains no one 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.
