摘要
Abstract
The PT100 temperature sensor is widely used in the industrial field, this article introduce a temperature collection system based on PT100,using Wheatstone bridge circuit and Three wire connection method, STC80C52RC MCU is used as control core, the 12 bit serial chip MAX1270 is used as the AD conversion chip. The system can work steadily and reliably by testing and ± 0.1℃control precision is ensured.关键词
