Methods: Single chip microcomputer (ATMEGA16) was used to programme for driving sensor (AM2311) and other periphery components so as to make a temperature and humidity meter of digital display. Results: As"verification regulation of digital temperature JJG(Su)99-2010" that was issued by Jiangsu quality and technical supervision bureau, the precision dew-point instrument YGM-2610 was adopted to test the temperature and humidity meter. The result indicated that it can achieve practical requirement, and its temperature and humidity data can output at the same time and they can be clearly display by using LED. Conclusion: The electric measurement of temperature and humidity obtains the advantages of digitization measurement. And it can enhance the accuracy through flexible twice calibrate procedure. Besides, the programming of microprocessor has good flexibility and programmability. It has abundant internal resources, while its cost and power consumption were low. And its expandability was well, and it can be repeatedly programmed.
