The aplication is to replace the thermostat.
Simulate the circuit to act as thermostat, and for the sensor to read resitance of circuit(in replace of thermostat). The resitance of thermostat goes higher as the temperature goes down. The sensor reads resistance of thermostat as it varies and...
Anyone,
I need a voltage controlled resistor that can produce 0 to 1M ohms resistence with 0 to 15vdc or 0 to 28vdc input power. Any suggestions? I heard FET can be used but how can I produce 0 to 1M?
