Design of intelligent temperature reporting system based on wireless rmote control - hardware design Abstract
Along with societys development and progress, temperature measurement and control seems more and more important.So, developing good performance of temperature controlling system has a very important significance.Our wireless remote control intelligent temperature reporting system is made of the radio transmission circuit (PT2262,SP wireless transmitting module), and the main circuit (wireless receiving circuit, the core of single-chip microcomputer AT89C2051 control circuit) Its main circuit includes four parts: the first part is to adopt DS18B20 chip for data acquisition; The second part is receiving module and decoder chip wireless PT2272 composition wireless remote control receiving; The third part is composed of LED nixietube temperature display circuit; The fourth part is composed of pronunciation chip speech broadcast circuit. The system is a smart temperature reporting system. This design has a lot of advantages, such as high accuracy, high precision, simple structure and so on.
