UV 3 Click Board™

Product Code: MIKROE-2736

The UV 3 Click Board™ is an advanced ultraviolet (UV) light sensor with I2C protocol interface. The click carries VEML6070 UVA light sensor designed by the CMOS process. UV 3 click runs on either 3.3V or 5V power supply. VEML6070 sensor features VEML6070 is an advanced ultraviolet (UV) light sensor with I2C protocol interface and designed by the CMOS process. The active acknowledge (ACK) feature with threshold windows setting allows the UV sensor to send out a UVI alert message. VEML6070 incorporates a photodiode, amplifiers, and analog/digital circuits into a single chip. VEML6070's 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. Specifications Type Optical Applications The UV 3 Click Board™ be used for UV measurement applications, sun exposure protection devices, display backlighting control, prototyping of wearables, handsets, and various consumer electronics based on received ambient or UV light On-board modules VEML6070 UVA light sensor Key Features Converts solar UV light intensity to digital data, excellent performance of UV radiation measurement under long time solar UV exposure Interface I2C Compatibility mikroBUS Click board size S (28.6 x 25.4 mm) Input Voltage 3.3V or 5V Pinout diagram This table shows how the pinout on the UV 3 Click Board™ corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
