description: Temperature measurement systems are used in a wide range of applications, covering all aspects of the industry and occupying important positions in a variety of fields. Starting from lowering development cost, expanding application range, stability and reliability of system operation, designing a temperature measurement device with PT100 platinum thermal resistance as temperature signal acquisition component, EW78E58 single-chip microcomputer as control core and OCMJ4@8C liquid crystal display as display device system. The measuring system not only can measure the temperature in the room, but also measure the temperature in liquid, seed, etc. In practical applications, the system is stable and reliable, and the circuit design is simple and practical. The accessories are part of the system circuit of the system.
