So, data collection system study is very important. This paper introduces a kind of based on single chip microcomputer temperature data acquisition system, using single-chip microcomputer and temperature sensor for distributed multi-channel data collection, and the collected temperature are shown through liquid crystal, also can use the buttons to set the value of the abnormal temperature, when measuring temperature beyond this unusual value can start a buzzer alarm prompt. This paper puts forward the design method of the circuit is simple to understand, low cost, measurement results are accurate, high stability.
