The AS7331 Evluation Kit enables initial sensor measurements with the AS7331 spectral UV-sensor. The AS7331 EVK hardware is split in two parts, the sensorboard with an I2C interface and a communication board with USB output where the sensorboard is connected to. Additional to this the EVK provides a comfortable GUI which enables the access to all sensor settings. Furthermore measurements can be recorded and exported via csv file for further analysises. Also a source development kit (SDK) is included in the EVK. This SDK provides prepared libraries and sample codes to support comfortable firmware design-ins.
