Abstract
Low cost temperature sensor for thermostats utilizing a calibration resistor and a microprocessor with switchable ports wherein said microprocessor selects between high impedance input or an output for a temperature sensing element and a calibration resistor where by selecting the input, the temperature sensing element or the calibration resistor are effectively removed from the circuit thus allowing the low cost temperature sensor to self calibrate itself.
