Keyestudio APDS-9930 attitude sensor module mainly uses APDS-9930 chip. APDS-9930 in a single 8 pin package can provide the ambient light sensor which is compatible with I2C interface and the infrared LED proximity sensor. The ambient light sensor uses double light diode to approximate the visual response of low lumen human under 0.01 lux illumination, and its high sensitivity allows the device to operate in the back of dark glass.

The proximity sensor which is completely adjusted can detect 100 mm object, and exempt the factory calibration requirements of terminal equipment as well as sub-components. From the bright sunlight to the dark room, proximity sensor’s proximity detection function can operate well. This module added micro optical lens can provide infrared energy efficient transmission and reception, which can reduce the overall power consumption. In addition, its internal state machine can make the device into a low power mode, bringing a very low average power consumption.
