Pick The temperature and humidity is suitable for human survival and growth of animals and all the necessary for the two most basic environmental parameters in modern life, the temperature and humidity of monitoring and control is very important meaning. The traditional test methods of temperature and humidity is through the test instrument, the method of artificial detection, low efficiency and accuracy. The paper introduced testing devices not only has can automatically detect temperature and humidity function, but also can control and display circuit by the CPU, alarm prompt etc. Function. This will improve the traditional detection performance of temperature and humidity. This system consists of 89S51 microcontroller, A/D circuit, temperature detection circuit, humidity display circuit, detection circuit, alarm circuit. Temperature and humidity detection circuit is will detect the temperature and humidity of the simulation, convert voltage ADC0809 conversion, the voltage 89S51 single-chip microcontroller, enter through input temperature and humidity and temperature and humidity compared to judge whether beyond the scope stipulated in the warehouse, when the temperature and humidity in set range, SCM wrong alarm circuit, signal. When the temperature or humidity is not set, microcontroller is within the scope of the alarming circuit, signal issued a warning signal hint carers to handle. Keywords: 89S51 microcontroller, A/D conversion, Wen/moisture detection. Display, alarm
