Temperature and humidity are two important environmental factors in some places like pharmacies, granaries and greenhouses. The design for the humidity and temperature monitoring system based on the MSP430F149 Single-Chip Microcomputer is presented in this thesis. The design of the system is characterized by accuracy in mensuration, convenience in debugging and real time information-recording and also widely used in the places which are too harsh for people to enter. The design grounded on the MSP430F149 Single-Chip Microcomputer, considering exsiting climate characteristics in our country, is planned in detecting system about parameters of humidity and temperature on the premise that has analyzing the working principle and pin function. The design has completed the schemes of humidity and temperature monitoring system, including temperature detecting system and humidity detecting system, to make sure the data size of the detection can meet the precise request in production and other links. There are five major parts in the scheme of humidity and temperature monitoring system, comprising temperature detecting system, humidity detecting system,display circuit and power circuit. The design adopts the MSP430 Single-Chip Microcomputer configuration by Texas U.S in the configuration of humidity and temperature moni
