VEML6075 UVA/UVB/UVINDEX Sensor~

This feature is not included in precompiled binaries

To use it you must compile your build. Add the following to user_config_override.h:

#ifndef USE_VEML6075
#define USE_VEML6075            // Add I2C code for VEML6075 sensor
#endif

This little sensor is a great way to add UVA and UVB light sensing to any microcontroller project. The VEML6075 from Vishay has both true UVA and UVB band light sensors and an I2C-controlled ADC that will take readings and integrate them. The sensor also comes with calibration registers so you can easily convert the UVA/UVB readings into the UV Index.

Configuration~

Wiring~

VEML6075 ESP8266
GND GND
VCC 3.3V
SDA GPIOx
SCL GPIOy

Tasmota Settings~

In the Configuration -> Configure Module page assign:

  1. GPIOx to I2C SDA (6)
  2. GPIOy to I2C SCL (5)

Commands and Use~

Console Commands Description values
VEML6075power Power on/off the modul 0/1
