The infrared temperature measurement technology plays an important role in the production process, the product quality control and the monitor, the equipment online breakdown diagnosis and the safe-keeping of security, as well as saved energy and so on. It broke the tradition measure pattern, and have many characteristics: quick response speed, high measuring accuracy, wide survey scope, and can simultaneously surveys the ambient temperature and the goal temperature, the survey distance amounts to 30 meters.
This design adopts to the SPCE061A single-chip and the TN9 sensor which bring about a simple infrared thermo-detector. SPCE061A is a 16 monolithic single- chip which produced by Ling Yang Science and Technology Company. In this single-chip sets two road DA transformation, eight road AD transformation, and the online simulation and so on. This has provides a convenient condition for the infrared thermo -detector which has the r pronunciation broadcast function. The system includes: SPCE061A, TN9 infrared temperature sensor, Keys and audio output part and so on. This precisely designing causes the electric circuit structure to be reasonable, and completely guaranteeing each kind of requirement, at the same time obtaining the system stability .
