| Abstract: | It is the key to measure resistance of thermo - resistance accurately in order to obtain exact temperature in use of thermo - resistance measuring temperature The paper gives a novel approach of thermo - resistance measuring in view of the disadvantage of tradition method. Using of single - chip computer AT89C51 achieve the idea with less other components, Experimental result shows the performance of system is reliable and high accurate of measure. |
| Keywords: | Thermo- resistance Measure Single - chip computer |
