arunadri.mj Posted July 23, 2005 Report Share Posted July 23, 2005 Hi all,I want to mesure the UV light using PIC16F877. Inturn i want to mesure the power output of a UV source. How can i achieve this?Any ideas, pointers, clues in this regard, no need to say i'd love to hear them.Thanks in advance,arun Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted August 6, 2005 Report Share Posted August 6, 2005 hi arun!are u interested in measuring its intensity? ;D Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted August 6, 2005 Report Share Posted August 6, 2005 I've UV LEDs produce a small voltage when exposed to UV light, connect one to a high impedance amplifier (an op-amp will do) and use an ADC or comparatoras the input for your PIC.
