Motion Sensor Sensor Switch Led 360 Degreec Human Body Sensor Light Switch Smart Home Microwave Sensor Switch Automatic Adjust 100% Brand New and High Quality. The microwave sensor is an active sensor, and the HF sensor emits high frequency electromagnetic waves (5.8 GHz) and receives their echoes. This sensor detects changes in the echo or even tiny movements within its detection range. The microprocessor triggers the "lights up" command. Signals passing through the door, glass plates and thin walls may be detected. Note: The detection of people or objects moving toward the lamp is more sensitive! 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. This product is a moving object sensor with a detection range of 360 degrees and an operating frequency of 5.8 GHz. The advantage of this product is stable working condition (stable operating temperature: 0 °C - 70 °C) This product uses a microwave sensor (high frequency output is less than 0.2lMw), so it is safe and performs better than infrared sensor. It can be installed in products made of glass or plastic, as these materials have little effect on the sensor.
