Using the bridge circuit, instrumentation amplifier, AD converter, microcontroller, control relays and boil-off cup, realizes control temperature control system to achieve the design requirements. Design requirements are as follows: 1, requires the ability to measure the temperature range is the ambient temperature to 100oC. 2, a digital thermometer, whichever is required maximum deviation of the measured temperature 1oC. 3, it is possible to control the temperature of the glass in the control of temperature deviation maximum 2oC, namely temperature fluctuations may not exceed 2oC, the accuracy of measurement is higher than the control accuracy. 4, the control target is 400W electric mug. 5, the implementation of the device for the relay, to control the temperature of the relay-off. 6, temperature measurement element is a platinum RTD Pt100 sensors. 7, the design of the circuit board and the use of single-chip learning program to achieve these requirements, and through the keyboard int
