描述
The ZOPT2202 Sensor integrates two types of ultra-violet light 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. A major application of the device is in smart phones or other mobile devices to enable UVA and UVB light measurements in support of diverse health care applications or contextual awareness algorithms.
特性
- Very high UVA and UVB light sensitivity combined with superior visible light and infrared light suppression
- UVA / UVB sensor in a matrix array arrangement; very stable spectral response over angle of light incidence
- Parallel operation of UVA and UVB sensor
- Configurable output resolution: 13 to 20 bits
- Configurable analog gain: x1 to x18
- Linear output code; large dynamic range
- Excellent temperature compensation
- Lowest conversion repeat noise
- Fluorescent light flicker immunity
- Programmable interrupt function for UVA or UVB sensor with upper and lower thresholds
- I2C interface capable of standard mode (100kHz) or fast mode (400kHz) communication; 1.8V logic compatible
