PT 100 To ADC
Hi all,
I have connected my PT 100 sensor to the bridge circuit which i added here gives the variations in Milli volts. I have used the ADC 0804 with AT 89S52 microcontroller.
I have the problem of the ADC did'nt give the value to the controller..
Is that the reason of the PT 100 output voltage is in mv?
Also the output of the bridge is two terminals. One terminal i have connected to +vin another terminal in which pin I have connect?
Is there any amplifier needed?
Kindly give me the solution..
Thank you.
