1. This product is a sensor for moving objects. It is based on principle and radar technology, using antennas and high-performance microchips. It is easy to install, provides high detection rate, low alarms, resistance to rain, fog, wind and dust, snow and extreme temperatures. 2. The detection range of the sensor is 360, its working frequency is 5.8GHz, and it is in a stable working state (stable working temperature: -35C-+80C). The product uses a microwave sensor (high-frequency output is less than 10mW) ). It can be installed in products made of glass or plastic 3. The microwave sensor uses the principle to transmit and receive high-frequency microwave signals (accurately perceive the movement of objects), through signal amplification and intelligent identification of the single-chip program, to control the on (lighting) and off (extinguishing) of the load 4. When someone enters the sensing detection range (within a diameter of 16m), the load lamp lights up; when the person passes through the sensing detection range and leaves and the set delay time countdown ends, the load lamp automatically turns off 5. This product can be set to not during the day and only when there are people at night; it can also be set to at any time as required. This product has a of light setting , which can be adjusted according to your needs to adapt to the lighting needs under different ambient light conditions. Working voltage: 220V-240V AC Load current: 7A Power frequency: 50/60H Time delay: 10 seconds to 30 minutes Frequency system: 5.8Hz+/-75 Mhz CW radar Transmission power: Less than 0.2mw Power consumption: Less than 0.5W Detection angle: 360 Installation : indoor, ceiling installation control: 10-2000lux Working temperature: -35-+80 Detection distance: 2-10 meters size:90 x 41 x 39mm Material:ABS+PC colour:white Package Contents: 1 x Motion Sensor Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
