Light-to-Digital I2C Sensor

The ISL29002 is an integrated light sensor with a built-in integrating type ADC and a standard I2C interface. The device transforms illuminance, ambient light level in lux, into a digital output signal accessible through I2C. The sensor precisely converts illuminance from 1lux to 100,000lux. The ADC features up to 15-bit effective resolution. The sensor includes another photodiode covered with metal to reduce the effects of dark output reading that may be significant in low lux levels.
