Yes FvM. You are correct. The UVTron send the pulse to PIC when the fire are detected. If no fire, the pulse also gone. Maybe you have any ideas how to developed a program using CCS to count the frequ ...
Hi..... i have a uvtron flame sensor to detect the flame / fire. I set this sensor to RB0 as a input. The problem is the PIC16F877A detect on of. After check datasheet, this sensor send a pulse when f ...
