Digital Display Thermometer Design Dased on single chip puter
Aiming at disadvantages of the traditional temperature measurement instrument own existence and exposure of difficult to use in real life, the lack of security, this paper proposes a non-contact infrared temperature measurement system design. The system is based on STC89C52 as infrared measuring temperature sensor data transmission and control core. In addition, design the function of liquid crystal displays, buttons and other peripheral modules. The biggest innovation in the system realizes the basic contactless temperature measurement function, its safety, convenience is more advantageous to the use of mon people. The infrared temperature measurement system is designed to simplify the circuit structure, improves the stability and reliability of measuring temperature. The system response speed, high transmission efficiency, high measurement precision, high reliability, etc. Will be petition and the traditional temperature measurement instruments, in the near future will have broad market prospects.
