Adafruit Lux/Light Sensor – VEML7700 I2C
The VEML7700 makes your life easier by calculating the lux, which is an SI unit for light. You’ll get more consistent readings between multiple sensors because you aren’t dealing with some unit-less values.
The sensor has 16-bit dynamic range for ambient light detection from 0 lux to about 120 klux with resolution down to 0.0036 lx/ct, with software-adjustable gain and integration times.
Interfacing is easy – this sensor uses plain, universal I2C. Adafruit have put this sensor on a breakout board with a 3.3V regulator and logic level shifter so you can use it with 3.3V or 5V power/logic microcontrollers. Adafruit have also written libraries for Arduino (C/C++) as well as CircuitPython (Python 3) so you can use this sensor with just about any kind of device, even a Raspberry Pi.
