More accurate than the infrared detecting human microwave sensors, microwave sensors, the body close to the sensor manufacturers contact Intelligent Technology Co., Ltd. of Shenzhen Tang. Microwave sensors, non-infrared and microwave sensors, microwave sensors is based on microwave Doppler principle, based on planar antenna sensor system for control of a sensor to the microprocessor. Teng Day smart microwave body sensor is to 10.525GHz microwave frequency transmitter, receiver, and the whole key components are imported components, program design, the choice of devices to ensure the reliability of the product. 
 Microwave sensors, infrared microwave sensor features: 
 A non-contact detection. 
 2 sensor from the influence of temperature, humidity, noise, air, dust, light, suitable for harsh environments. 
 (3) the ability of anti-radio interference. 
 The detection range of 10mm-3m, and adjust according to customer requirements. 
 5 Teng Day smart ATM microwave body sensor performance and stability, long life. 
 6. Power green light is on, 17S, 17S delay formal entry into the state. 
 Tune indicator potentiometer counterclockwise rotation sensitivity weakened from narrow, twisted in the end to turn off. Clockwise rotation, the sensitivity increases, the distance increases, the twist in the end the fetters machine, the sensitivity is too high, the microwave has been in the alarm state.
