Abstract：A new kind of instrument for weather measurement is designed and its main technical index and function are reported. The selection of working principle of electric circuit of sensor, software design and test results are analysed. The precision is compared with that of Vaisala PTU300,they are consistent with each other.By using high accuracy HD9008TR temperature and humidity sensors, MS5534C air pressure sensors, and advanced electronic circuitry design, the instrument’s characteristics is of high accuracy, stability, expansibility, high ratio of performance to price, to satisfy the conventional requirement of weather detecting department.
