Description

The SparkFun Qwiic VEML7700 Ambient Light Sensor provides accurate, 16-bit ambient light readings from 0 to 167,000 lux via the I²C interface. This miniature sensor (6.8mm x 3.0mm x 2.5mm) features a high-sensitivity photodiode, a low-noise amplifier, and a 16-bit analogue-to-digital (A/D) converter. Its unshifted 7-bit I²C address is 0x10.

This Qwiic breakout board routes power (VDD/GND) and I²C signals (SDA/SCL) to two Qwiic connectors, plus a 0.1in.-spaced PTH header for both solderless and soldered applications. We offer an Arduino Library and Python package to quickly convert raw sensor data into lux, with automatic compensation for gain and integration time.
