Adafruit VEML7700 Lux Sensor - I2C Light Sensor

The VEML7700 lux sensor by Vishay simplifies ambient light detection with precise lux calculations, an SI unit for light measurement. Unlike typical light sensors, it ensures consistent readings across devices.Featuring a 16-bit dynamic range, it detects ambient light from 0 lux to approximately 120 klux with a resolution of 0.0036 lx/ct. The software-adjustable gain and integration times enhance its versatility.Interfacing is straightforward with universal I2C connectivity. The sensor comes on a breakout board with a 3.3V regulator and logic level shifter for compatibility with both 3.3V and 5V microcontrollers.Libraries for Arduino (C/C++) and CircuitPython (Python 3) broaden its usability, making it compatible with devices like the Raspberry Pi. Moreover, SparkFun Qwiic compatible STEMMA QT connectors allow for a truly solder-free experience.The excitement of this sensor extends with no-solder wiring options, easily connecting to popular micros like the ESP32 V2 Feather via STEMMA QT adapter cables. While the QT Cable is sold separately, multiple options are available.This is a notable design by Kattni for Adafruit, marked with a signature on the back of the PCB.
