Small, digital, and extremely economical

The SFH 5712 detects ambient brightness in the same way as the human eye, and offers not only the I²C standard data rates but also highspeed rates of up to 3.4 MHz. Without the need for any additional control commands, an integrated circuit in the sensor automatically provides a measured value twice a second. The sensor has only four connections and takes up very little space. It can easily communicate through its integrated I²C interface. No analog circuit elements are needed. With 150 μA during operation and only 1.5 μA in stand-by mode, the sensor consumes extremely little power.
