Digital Ambient Light Sensor SFH 5712
Digital sensor technology
OSRAM Opto Semiconductors' new Ambient Light Sensor SFH 5712 detects brightness in the same way as the human eye. Designed for a wide range of applications, it can be used in situations where systems and equipment need to adapt to ambient light conditions as perceived by the human eye. The SFH 5712 can be easily controlled by its integrated I²C interface.
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.
