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. https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2025-11-03 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2025-12-20 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-01-26 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-01-29 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-02-01 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-03-15 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-03-18 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-04-08 https://elecena.pl/product/29478477/adafruit-veml7700-lux-sensor-i2c-light-sensor 2026-04-15
