The measurement of temperature and humidity is critical to agricultural production. Therefore, by comparing a variety of temperature and humidity measurement methods, design a microcontroller-based tester of temperature and humidity . This design uses 51 single core processor STC89C51 by air temperature and humidity sensors of the measured data into the microcontroller, operation processing, culminating in LCD016L display the measurement result . System is based on a design of modular to determine each module unit, and select the appropriate electronic components, and circuit design further. System hardware circuit by the MCU peripheral circuit, sensor circuit, power circuit, liquid crystal display circuit and other components .On this basis, design system software; software parts includes module of On this basis, design system software; software part includes control module, the module of temperature and humidity sensor, the module of power and the module of human-machine interaction programming ,the module of temperature and humidity sensor, the module of power and the module of human-machine interaction programming. Schematic circuit is simulation in the proteus, and simulation results show that schematic is viable. According to design, the measuring instrument of air temperature and humidity may have the advantages of easy operating, easy reading and having precise measurements. Keywords:temperature
