24GHz Medium-space presence sensor(Tuya Zigbee version)
MSA220 Z is a 24GHz radar sensor based on Merrtek patented multi-array high-gain. Its antenna gain is high, and it is especially suitable for detection of human body existence information after people enter deep sleep within the range of a bed. Combining with the special algorithm of Merrytek, it can accurately detect the subtle movements brought about by vital signs after people enter deep sleep on the bed. Thus, it provides fast and accurate front-end sensing input for cardless power access of smart hotels based on the presence of human bodies.

Product Package
Start Process & Initialization
When the first power-on, indicator turns off after flashing for 20 seconds. Sensor does not detect moving signal during initialization. Turning ON/OFF indicator, hold time and detection area can be se by APP.
Factory setting
Detection Area:100%, Hold Time: 5min, Indicator light: open
Detection signal
The product detects human moving, minor moving, and presence signals, and realizes the detection of human-existing/no-human in sleep state. The following is a description of the moving, minor moving and presence signals:

1. Our sensor is recommended layout in UPS circle to guarantee instant smart scene execution or electrical appliance operation.
Installation suggestion
Our sensor is suggested installed heading to human chest or adjust its sensing antenna toward human chest for best detection result.
