Ambient Light Sensor (0-200klx)

by DFRobot

This new ambient light sensor is packaged in a transparent hemisphere case that offers better light-gathering power. The sensor supports a 0-200klx detection range and I2C communication.

The on-chip photodiode’s spectral response is optimized to mimic the human eye’s perception of ambient light and incorporates IR and UV blocking capability. The adaptive gain block automatically selects the correct lux range to optimize the counts/lux. It is ideal for applications such as smartphones, vehicle smart lights, intelligent incubators, etc.
