Digital Ambient Light Photo Sensor with I2C Output

Currently Viewing:

The APDS-9306-065 is a low-voltage digital ambient light sensor that converts light intensity to digital signal output with I2C interface. It consists of photodiode, ADC, oscillator and power-on reset to ensure consistent start-up. The APDS-9306-065 approximates the response of the human eye and provides direct read out where the output count is proportional to ambient light level.
