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 the sensor.
