UVA and UVB Light Sensor with I
2
C 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 I
2
C (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.
FEATURES
• Package type: surface mount
• Dimensions (L x W x H in mm): 2.0 x 1.25 x 1.0
• Integrated modules: ultraviolet sensor (UV), and
