VEML6070 UV light sensor~

This feature is included only in tasmota-sensors and tasmota32 binaries

When compiling your build add the following to user_config_override.h: 

#ifndef USE_VEML6070
#define USE_VEML6070                           // [I2cDriver12] Enable VEML6070 sensor (I2C addresses 0x38 and 0x39) (+1k5 code)
  #define USE_VEML6070_RSET    270000          // VEML6070, Rset in Ohm used on PCB board, default 270K = 270000ohm, range for this sensor: 220K ... 1Meg
  #define USE_VEML6070_SHOW_RAW                // VEML6070, shows the raw value of UV-A
#endif

This little sensor is a great way to add UV light sensing to any microcontroller project. The VEML6070 from Vishay has a true UV A light sensor and an I2C-controlled ADC that will take readings and integrate them for you over ~60ms to 500ms." See VEML6070 UV Sensor for more information.

Configuration~

Wiring~

VEML6070 ESP
GND GND
VCC 3.3V
SDA GPIOx
SCL GPIOy

Tasmota Settings~

In the Configuration -> Configure Module page assign:

  1. GPIOx to I2C SDA
  2. GPIOy to I2C SCL

Tasmota Main~

After a reboot the driver will detect VEML6070 automatically and display UV light intensity.
