The SFH 5712 is a low-vol tage digital ambient light sensor that converts light intensity to digital signal output capable of direct I2C interface. It offers not only standard data rates but also high speed rates of up to 3.4 MHz. An integrated circuit in the sensor automatically provides a measured value between 3 and 65,000 lux twice a second, with no need for additional control commands. The sensor has four connections, and measures 2.0 × 2.0 × 0.7 mm. It can be controlled via its integrated I2C interface. Ambient light adjusted brightness extends the interval between recharges and improves readability. The SFH 5712 is primarily intended for mobile applications in which the brightness of the display is constantly adjusted according to available ambient light.
