Hi there,
i want to ask you how can i connect a smoke detector who is giving me an output voltage of 2.20V to 2.50V (which is not constant) when it detect smoke and 0V when it doesn't detect smoke.
for the PIC16F877A, i need a constant voltage of either 0V or 5V
Can anyone help me with this problem, PLEASE !
