Product Introduction
I.Digital UV SensorGUVB-C31SM Product Description
The digital UV sensor GUVB-C31SM can be easily connected to an MCU in applications to achieve desired functions. The digital UV sensor itself integrates
a photodiode, amplifier, ADC, digital control logic, and I2C interface circuit for measuring UVB radiation.
The digital UV sensor GUVB-C31SM can separately measure the intensity of medium-wave ultraviolet and calculate digital output based on each intensity. According to specific application requirements,
reasonable use of power management modes can reduce power consumption.
II. Applications of Digital UV Sensor GUVB-C31SM
Smartphones, watches, weather stations
Bicycle navigation, games, accessories
