CM3512UV

   CM3512UV 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 astrong solar UVI condition, the smart ACK ** can be easily implemented by the software 
programming.

  CM3512 incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip.  
CM3512's adoption of Filtron? 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. CM3512 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 CM3512's operating voltage ranges from 2.7 V to 5.5 V.
