Abstract:

Based on the principle of integral circuit and thermal element, the present study considers the application of 80C51 single-chip micro-computer into the design of intelligent temperature control system. In this paper, the main approach is to make the ambient temperature change in accordance with the pulse width variation. The process is realized through the integral circuit consisting of the thermal resistor, capacitor and operational amplifier. In this way, with the pulse width measurement, we can detect the ambient temperature as well as control the external circuit. The experiment indicated that the system simplifies the temperature measurement with high reliability, great convenience and wide applications.
