The high-frequency output of the sensor is less than 10mW, which only accounts for one percent of the mobile power of mobile phones and microwave ovens. The microprocessor triggers the "light up" . Signals passing through doors, glass panels, and thin walls may be detected. Note: Detection of people or objects moving towards the lamp is more sensitive! Microwave sensors are active sensors that emit high-frequency electromagnetic waves (5.8 GHz) and receive their echoes. The sensor can detect changes in the , and even small movements within its detection range. The 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 conditions (stable working temperature: 0 Celsius- + 70 Celsius), Weight: 0.1763698096 Pounds, Manufacturer: Tuidzljd
