(3) its working power both can be introduced at far-end, also can adopt the parasite power mode to produce.
(4) Du Te one-wire interface mode.DS18B20 only needs a Tiaokou line can realize the both-way communication of microprocessor and DS18B20 when being connected with microprocessor.
(5) DS18B20 supports the multiple spot networking function.A plurality of DS18B20 can be connected in parallel on unique three-way on, realize multi-point temperature measurement, can save a large amount of lead-in wires and logical circuit
Keyboard 6 is a matrix keyboard, adopts ranks parallel lines layout type, and the alignment staggered place of being expert at embeds a button.
The model that PIC single-chip computer control system 2 adopts is the PIC16F877 single-chip microcomputer.
The utility model is to utilize single-chip microcomputer to make up the hardware platform architecture that a distributed temperature is gathered, and utilizes computing machine to carry out centralized control as the upper strata.Parameter settings such as temperature can be carried out two-stage by single-chip microcomputer or computing machine and freely set.
Though through the utility model is described in conjunction with specific embodiments, for the skilled personage in present technique field, according to substituting of making of narration above, revise with variation will be conspicuous.Therefore, such substituting, in the spirit and scope that modifications and variations fall into attached claim the time, should be included in the utility model.
