The Haitronic APDS-9930 proximity sensor combines proximity detection and an ambient light sensor (ALS) in an optical module with an infrared LED. Its light measurement approximates the response of the human eye, with low-light performance from 0.01 lux and resolution up to 16 bits. Proximity detection is fully calibrated for distances up to 100 mm and works behind dark glass.

The module features programmable upper and lower threshold interrupts, a sleep timer and a synchronous LED driver. The I2C interface supports speeds up to 400 kHz, while the dedicated interrupt pin and standby and sleep modes support applications such as display brightness adjustment, touchscreen deactivation and hands-free activation.
