# Octopus Analog UV sensor (GUVA-S12SD)(EF04093) ## Introduction Octopus Analog UV sensor (GUVA-S12SD) is the UV electric brick in our Octopus series, the basic design is from the Octopus electric bricks and the setting of its outlook, the PCB fixing hole and the connectors are the same. It can measure the total UV intensity of the sunlight; linear signal voltage output; and it can be used as UV dosimeters, UV index instrument and flame detection,etc,. ![](https://raw.githubusercontent.com/elecfreaks/learn-cn/master/microbitSensor/sensor/images/04093_00.jpg) ## Products Link [ELECFREAKS Octopus Analog UV Sensor (GUVA-S12SD)](https://shop.elecfreaks.com/products/elecfreaks-octopus-analog-uv-sensor-guva-s12sd?_pos=1&_sid=cae0131c1&_ss=r) ## Characteristics Design for the occasions need reliable and concise UV index. Support micro:bit in 3V. Easy and convenient for connection. ## Parameter Name: Octopus Analog UV sensor (GUVA-S12SD) SKU:EF04093 Working Voltage: DC 3~5.5V Connection Mode: G-GND,V-VCC,S-signal pin Test Precision: ±1 UV INDEX Wave length: 200nm-370nm Response Time: Below 0.5 second Size: 38.9x23.5mm Net Weight: 5g ## Dimensions and Outlook ![](https://raw.githubusercontent.com/elecfreaks/learn-cn/master/microbitSensor/output/images/eNbM5Kz.png) ## Quick to Start ### Hardware Connection Connect the module with the wire(with buckle) to the PI pins on the Octopus:bit, insert the micro:bit to the Octopus:bit. ![](https://raw.githubusercontent.com/elecfreaks/learn-cn/master/microbitSensor/output/images/04095_2.png) ### Software Programming Programme in the makecode and analog read P1 to get the intensity of the UV that would be displayed on the micro:bit.
