Description

The ZOPT2201 Sensor integrates an ambient light sensor (ALS) and ultraviolet energy sensor (UVS). The device can be connected via an I2C interface to an external 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 brightness control of display panels (ALS) and diverse health care applications or contextual awareness algorithms (UV).
