UV Sensor

Measuring range: 55 -110 dB(A)

Resolution: 0.1 dB(A)



I. Working principle

When ultraviolet photons irradiate the surface of a material, it will excite electrons in the material to jump from atomic orbitals to neighboring atomic orbitals, forming electron-hole pairs. The number of these electron-hole pairs increases with increasing amounts of UV radiation. In the electrode of the sensor, the number of electron-hole pairs will cause a change in current. The circuit will amplify this current change and convert it into a digital signal. The output digital signal will be processed by relevant algorithms to obtain ultraviolet radiation data.
