Data Access
VEML6075 has 16-bit high resolution sensitivity for each UV channel. One byte is the LSB and the other byte is the MSB. The
host needs to follow the read word protocol as shown in fig. 7. The data format shows as below.
Note
• Data byte low represents LSB and data byte high represents MSB.
Data Auto-Memorization
VEML6075 keeps the last results read. These values will remain in the registers, and can be read from these registers, until the
device wakes up and a new measurement is made.
UV-Index Calculation
In order to use the result data to calculate the UV-Index, please refer to the “Designing the VEML6075 into an Application”
application note (www.vishay.com/doc?84339
).
