This system is better than analogue thermostat system which has poor accuracy. A digital temperature controller circuit is a precise temperature controller in medical industrial and home applications. The controller has been designed and fabricated using the op amp ic 741 and a 1k thermistor as the temperature sensor.
You can build a temperature controller circuit with the 555 ic together with a thermistor resistor divider.
The ratio arms r1 and r2 of the bridge are kept fixed say unity. With these types of sensors stabilities of 0 01 c to 0 001 c are commonly achievable. The ratio arms r1 and r2 of the bridge are kept fixed say unity. The temperature sensors are typically thermistors rtds or linear devices such as the lm335 or ad590.
