1. UV Sensor User Manual UV Sensor User Manual 1 Features Boost convertor chip SGM8521 Operating voltage 3 0V 5 5V Output type TTL level output Responsive 200nm 370nm wavelength Dimensions 21 0mm 13 0mm Fixing hole size 2 0mm Operating principle Waveshare This module has an UV sensor GUVA which is a ideal device for detecting the amount of UV ray without wavelength filter since it is UV ray sensitive only In other word the wavelengths of 365nm UV A and 320nm UV B are the cut off thresholds of GUVA 2 Applications This module can be applied to UV ray detecting system outdoors UV monitoring device sterilizing lamp and etc 3 Interfaces Pin No Symbol Descriptions 1 AOUT Analog output 2 GND Power ground Positive power YOC supply 3 0V 5 5V 4 How to use We will illustrate the usage of the module with an example of UV ray testing by connecting a development board Download the relative codes to the development board 2 Connect the module to the development board via a serial wire then power up the development board and start the serial debugging software Here is the configuration of the connection between the module and the development board Port STM32 MUC pin AOUT GPIOA 6 GND GND VCC 3 3V UV Sensor User Manual Port Arduino pin AOUT AO GND GND VCC 5V Here is the configur2. ation of the serial port Baud rate 115200 Data bits 8 Stop bit 1 Parity bit None Waveshare Turn on a currency detector and illuminate its UV ray to the UV sensor You will find that the serial port outputs relative data from the test
