Ambient Light Sensor Provides I²C Output

The SFH 5712, a low-voltage digital ambient light sensor, employs an I²C interface and is capable of detecting ambient brightness in the same manner as the human eye. As per the company, it is the only sensor on the market that offering both standard and high-speed data rates up to 3.4 MHz. An IC in the sensor automatically provides a value between 3 and 65,000 lux twice per second without the need for any additional control commands. The sensor requires only four connections and measures 2 mm x 2 mm x 0.7 mm. Primarily targeting mobile applications, it consumes 150 µA during operation and 1.5 µA in standby mode.
