I need help with interfacing resistive sensor
(OP)
Hi!
I need help with interfacing resistive sensor to microcontroller. Sensor resistance changing between 100kohm to 2Megaohm. I must use only one pin on controller. That mean I need some kind of relay output circuit. But which kind of circuit give me good results.

RE: I need help with interfacing resistive sensor
What you need is a temperature transmitter. The device will take the sensor output and give you a control signal (i.e. 4-20ma or 0-10v) that the controller will recognize. Check out www.kele.com. They have transmitters for a variety of sensors and applications. I hope this helps.
