Abstract: Most current society of granary temperature and humidity detection work experience or use personal judgment and manual control stage, because human experience is not accuracy, so can not accurate to test the temperature humidity in the granary and many times to collect more artificial experience control efficiency is low, the granary administrator is uneven, prone to uncertainty, and then cause grain storage and mildew. Aiming at the above problems, this paper gives a grain warehouse temperature and humidity monitoring system based on single chip microcomputer. The system mainly consists of single chip microcomputer, temperature and humidity sensor, display module and alarm module. The temperature and humidity sensor detects the temperature and humidity inside the granary in real time, and sends the temperature and humidity data to the SCM through a single bus. After processing the data, the temperature and humidity data are sent to LCD1602 for display. When the temperature and humidity exceed the preset upper and lower limits, the system will give a voice alarm. The experimental results show that the temperature deviation of the system is ± 1 ° and the humidity deviation is ± 3%, which basically meets the expected design requirements.
