【正文】 the TN9 sensor which bring about a simple infrared thermodetector. SPCE061A is a 16 monolithic single chip which produced by Ling Yang Science and Technology Company. In this singlechip 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 pletely guaranteeing each kind of requirement, at the same time obtaining the system stability .
