BR1810-C-F is a morning object sensor that can detect range of 360 degree and it’s working frequency is 5.8 GHz. The advantage of this products  is stable working state (stable working temperature: -40°C to 70°C), BR1810-C-F adopts a microwave sensor (high-frequency output less than 0.2mW), so that it is safe and performs better than infrared sensor.
