1. This product is a sensor for moving objects. It is based on Doppler principle and radar technology, using antennas and high-performance microchips. It is easy to install, provides high detection rate, low false 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: -35°C-+80°C). The product uses a microwave sensor (high-frequency output is less than 10mW) ). It can be installed in products made of glass or plastic3. The microwave sensor uses the Doppler 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 lamps4. 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 off5. This product can be set to not light up during the day and light up only when there are people at night; it can also be set to light up at any time as required. This product has a variety of light setting options, which can be adjusted according to your needs to adapt to the lighting needs under different ambient light conditions.Working voltage: 220V-240V ACLoad current: 7APower frequency: 50/60HTime delay: 10 seconds to 30 minutesFrequency system: 5.8Hz+/-75 Mhz CW radarTransmission power: Less than 0.2mwPower consumption: Less than 0.5WDetection angle: 360°Installation method: indoor, ceiling installationLight source control: 10-2000luxWorking temperature: -35℃-+80℃Detection distance: 2-10 meterssize:90 x 41 x 39mmMaterial:ABS+PCcolour:whitePackage Contents:1 x Motion SensorOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
