1、The microwave sensor is an active sensor, and the HF sensor emits high frequency electromagnetic waves and receives their echoes. 2、This sensor detects changes in the echo or even tiny movements within its detection range. 3、The microprocessor triggers the "lights up" command. Signals passing through the door, glass plates and thin wall may be detected. 4、The high-frequency output of this sensor is less than 10mW, which is only one percent of the mobile power of mobile phones and microwave ovens. 5、This product is a moving object sensor with a detection range of 360 degrees and an operating frequency of 5.8 GHz. 6、With stable working condition, the stable operating temperature is 0 °C - +70 °C. 7、This product uses a microwave sensor (high frequency output is less than 0.2lMw), so it is safe and performs better than infrared sensor. 8、It can be installed in products made of glass or plastic, as these materials have little effect on the sensor.
