UV 4 click is a powerful Ultra Violet (UV) sensing device and Ambient Light Sensor (ALS) Click board™, featuring a sensor with a very wide dynamic range of detectable light intensity, across two ADC range settings. The UV diodes are matched to CIE erythema action spectrum, allowing a very accurate calculation of the UV index. The UV Index is standardized by the World Health Organization and it represents the strength of sunburn-producing (UV) radiation.High accuracy UV index sensor (0 to > 20uV) Matches erythermal curve Ambient light sensor <100 mlx resolution possible, allowing operation under dark glass Up to 128 klx dynamic range possible across two ADC range settings Industry’s lowest power consumption 1.62 to 3.6 V supply voltage <500 nA standby current Internal and external wake support Built-in voltage supply monitor and power-on reset controller Wearables Handsets Display backlighting control Consumer electronics
