5.8GHz Toilet Wireless Radar
Transceiver Module

Model:
RADAR5.8G Toilet

WENSHING Electronics release the RADAR5.8G Toilet (Dopple) long-distance power-saving human body motion detection module series in November 2022. The RADAR5.8G Toilet is in the 5.8GHz legal ISM band. This is to use the principle of radio wave reflection to design human body detection. The Doppler intermediate frequency effect is generated due to human body movement. The intermediate frequency is ***ed in the circuit design, and the intermediate frequency is detected through DSP to know whether there is any Triggered by object movement. It is save the user's cost. The detection distance is up to 10 meters, the minimum operating voltage is 2.1V, and the power consumption current only 90uA.
