UVA Light Sensor with I²C Interface
DESCRIPTION
VEML6070 is an advanced ultraviolet (UV) light sensor with
I²C protocol interface and designed by the CMOS process.
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 signal
can be easily implemented by the software programming.
VEML6070 incorporates a photodiode, amplifiers, and
analog / digital circuits into a single chip. VEML6070’s
adoption of Filtron^TM 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 1 μA. VEML6070’s operating voltage ranges from
2.7 V to 5.5 V.
