waveshare UV Detection Sensor Module 200nm370nm Wavelength Ultraviolet Ray Detector Module for Arduino Support DC 3V and 5V

Overview Output voltage boosts along with the ambient ultraviolet intensity increases Onboard amplifier circuit with adjustable amplification factor Specifications Response spectrum: 200nm-370nm Dimension: 22.0mm * 16.0mm Mounting holes size: 2.0mm Applications Ultraviolet tester Outdoor ultraviolet detector How to Use In the case of working with a MCU: VCC ? 3.3V ~ 5.0V GND ? power supply ground AOUT ? MCU.IO (analog output) Downloads Development resources: demo codes, schematic, datasheets, etc. Wiki:www.waveshare.com/wiki/UV_Sensor?Amazon Package Content UV Sensor x1 3-pin custom connector jumper wire x1 FAQ The output voltage of the UV sensor is very low. Why? The output voltage of the UV sensor increases with the enhancement of the ultraviolet intensity. And the maximum output voltage of UV sensor is 2-3V. When the ultraviolet intensity is not strong, the output voltage may be in the range of 0.01-0.1V. It's recommended to test the module outdoor or irradiate the module with UV LED.
