VEML6070 SENSOR BOARD AND DEMO SOFTWARE
The small blue VEML6070 sensor board fits to the SensorXplorer
TM
demonstration kit.

With the help of the VEML6070 sensor board and the demo software, one can easily test the UV sensor. Four possible
integration times are selectable. Associated result counts are strictly linear, meaning a factor of 2 in integration time results in
a factor of 2 in output data counts.

In addition to the raw data read out of registers 0x71 and 0x73, the corresponding UV-index is shown, as well as the risk level
indicated with the changing color (fig. 6).
