VEML6070

VISHAY  VEML6070.  紫外线光传感器, 355NM, I2C

The is an advanced ultraviolet 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 an UVI alert message. Under a strong solar UVI condition, the smart ACK signal can be easily implemented by the software programming. This light sensors incorporates a photodiode, amplifiers and analog/digital circuits into a single chip. 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. 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 1µA.
