Infrared temperature measurement technology in the production process, product quality control and monitoring equipment, on-line fault diagnosis and safety protection and energy saving has played an important role. It has broken the traditional temperature measurement mode, and has no influence to the temperature of the measured object is the temperature field, high resolution, fast response, high accuracy, wide measuring range, is not affected by the temperature upper limit, good stability and can measure the environment temperature and target temperature measurement, the longest distance is 30 meters.
Infrared thermometer is the blackbody radiation law as the theoretical basis, is the product of development of optics theory and microelectronics. Compared with the way of traditional temperature measurement, has the advantages of short response time, non-contact, no interference by temperature field, long service life, convenient operation and a series of advantages. Infrared temperature measurement system of the design is a kind of convenient temperature measurement tool, the function is stable, fast running speed, can be used as a simple non-contact temperature measuring meter. The system can real-time detection, display the temperature information of the current environment. This system is mainly used MLX90614 infrared temperature sensor and STC89C52 SCM
At present, microcontroller communicates with MLX90614 through IIC, the temperature for reading data processing, after driving LCD5110 module temperature measurement
