Hi,
I'm just getting back in to Electronics and am not progressing as well as I would hope. I have been playing around with a pressure sensor I bought trying to come up with the correct output when pressure is applied.
Attached is the circuit I am currently running with.
What I am hoping is that the output I measure can be between 0 and 5 volts but I can't seem to get the 0 pressure reading to be 0 volts or the max pressure to be 5V. I have played around with the final 1k resistor on the output but it doesn't seem to do much. As you can see the current output is between 1.49V and 1.52V based on the pressure applied. Eventually the output needs to go to a PIC components ADC input so I can evaluate the pressure. I'm not sure if this small voltage range is going to work when the ADC converts.
Can someone give me some help as to what I should change on the circuit to get a better voltage range at the output?
Thanks,
Craig
