Analog UV Light Sensor Breakout — GUVA-S12SD

designed for detect­ing and mea­sur­ing ultra­vi­o­let radi­a­tion. It can be used in a wide range of appli­ca­tions includ­ing UV index mon­i­tor­ing for wear­able devices, smart­phones, and out­door UV detec­tors, as well as UV inten­si­ty mon­i­tor­ing, flame detec­tion, and dis­in­fec­tion sys­tems.The mod­ule is ful­ly com­pat­i­ble with pop­u­lar MCU plat­forms such as the Arduino series, mak­ing it ide­al for devel­op­ers, hob­by­ists, and researchers. It sup­ports two con­nec­tion options: an anti-reverse plug inter­face and a nee­dle pin inter­face, both with a 2.54 mm pitch. An addi­tion­al expan­sion board ensures seam­less inte­gra­tion with Arduino Uno R3 and oth­er MCU boards, sim­pli­fy­ing wiring and pro­to­typ­ing.Specification :Work­ing Volt­age: DC 3.3V ~ 5VInter­faces: Anti-reverse plug / Nee­dle pin inter­face (2.54 mm pitch)Mount­ing Hole Size: 3 mm diam­e­terCon­duc­tor Length: 200 mmOut­put Sig­nal: Ana­logSpec­tral Detec­tion Range: 240 nm – 370 nmActive Area: 0.076 mm²Response Rate: 0.14 A/WDark Cur­rent: 1 nAPho­tocur­rent: 101 ~ 125 nA (under UVA lamp, 1 mW/cm²)YouTube link :
