Description
The ZOPT2202 Sensor integrates two types of ultra-violet optical sensors: one that is primarily sensitive in the UVA spectral range and one that is sensitive in the UVB spectral range.
The device is connected via an I²C interface to a microcontroller. Other I²C or SMBus devices can be connected to the same interface. The device has a programmable interrupt with hysteresis to respond to events and reduce the microcontroller tasks.

FEATUREs
◾ Very high sensitivity for UVA and UVB energy levels
◾ Superior visible light and infrared energy suppression
◾ Very stable spectral response over angle of light incidence
◾ Large dynamic range
◾ Excellent temperature compensation
◾ Lowest conversion repeat noise
◾ Parallel operation of UVA and UVB sensor
◾ I²C interface capable of standard mode (100kHz) or fast mode
   (400kHz) communication; 1.8V logic compatible
◾ Programmable interrupt function for UVA or UVB sensor with
   upper and lower thresholds

Sensor Features
