VEML6075
Vishay Semiconductors
UVA and UVB Light Sensor with I2C Interface
DESCRIPTION
The VEML6075 senses UVA and UVB light and incorporates
photodiode, amplifiers, and analog / digital circuits into a
single chip using a CMOS process. When the UV sensor is
applied, it is able to detect UVA and UVB intensity to provide
a measure of the signal strength as well as allowing for UVI
measurement.
The VEML6075 provides excellent temperature compensation
capability for keeping the output stable under changing
temperature. VEML6075’s functionality is easily operated via
the simple command format of I2C (SMBus compatible)
interface protocol. VEML6075’s operating voltage ranges
from 1.7 V to 3.6 V. VEML6075 is packaged in a lead (Pb)-free
4 pin OPLGA package which offers the best market-proven
reliability.

VEML6075
Vishay Semiconductors
Digital Interface
The VEML6075 contains a CONF register (00h) used for operation control and parameter setup. Measurement results are stored
in four separate registers, one each for UVA, UVD, UVB, UVcomp1, and UVcomp2 (07h to 0Bh respectively). All registers are
accessible via I2C communication. Fig. 7 shows the basic I2C communication with the VEML6075. Each of the registers in the
VEML6075 are 16 bit wide, so 16 bit should be written when a write command is sent, and 16 bit should be read when a read
command is sent.
The built in I2C interface is compatible with I2C modes “standard” and “fast”: 100 kHz to 400 kHz
