This article has designed a Z-temperature sensor contained Z-sensitive component and temperature Sensor meter has been designed. The sensor uses the excellent quality of Z-sensor

which is high export amplitude and frequency export. The sensor overcomes the imperfection of Z-sensor

which is nonlinear and disperse quality. The Z-temperature sensor and single-chip processor have been inosculated each other. The sensor has many func- tions

such as small volume

low cost and standard digit export. The experimental results showed that the maximum error between the export designed of Z-temperature sensor and the linear export expected is less than ±1 ℃

this meets common application. The method in this paoer can be used in other design which contains analog signal.
