Hi I wish to make a IR Flame sensor. I have made a schematic as below.
But I could not determine the values for R(x) & Rpot(y). I have tried x = 10K, y=10K , x=1K , y=10K,etc (randomly). But I could not fully control the output using the potentiometer.
I need to fully control the output using the potentiometer. Please help me calculate the values of x and y. Also let me know if anything else cold be added for the better functioning of the sensor.
