Red Arrow HLBDS Daylight IP20 High/Low Bay Sensor 1-10V Plastic

The daylight Sensor can read and measure the surrounding light, and convert the amount of light 1-10V electronic signal output. A potentiometer is employed for end users to set the brightness level, so that the daylight sensor can read, measure the available natural daylight against the targer value, and calculate how much artificial light is needed. The demand is then converted to 1-10V signal to be sent to the 1-10V dimmable ballast or LED driver, which will then adjust the light output relative to the available ambient light.
