DESCRIPTION
VEML6070 is an advanced ultraviolet (UV) light sensor with I2C protocol interface. It is easily operated via a simple I2C command. The active acknowledge (ACK) feature with threshold windows setting allows the UV sensor to send out a UVI alert message.Under a strong solar UVI condition, the smart ACK signalcan be easily implemented by the software programming.


VEML6070 incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip. VEML6070’s adoption of FiltronTM UV technology provides the best spectral sensitivity to cover UV spectrum sensing. It has an excellent temperature compensation and a robust refresh rate setting that does not use an external RC low pass filter.


VEML6070 has linear sensitivity to solar UV light and is easily adjusted by an external resistor. Software shutdown mode is provided, which reduces power consumption to be less than 1uA. VEML6070’s operating voltage ranges from 2.7V to 5.5V.

Features:

  • UV spectrum sensitivity: 320-410nm (peak at 355nm)
  • Voltage Supply: 2.7-5.5V
  • I2C interface
  • Product Dimensions: 14.0mm x 13.0mm x 3.0mm / 0.6″ x 0.5″ x 0.1″
  • Product Weight: 0.5g / 0.0oz

This UV sensor works great with 3 or 5V power or logic, its nice and compact, and its easy to use with any I2C-capable microcontroller.
