Research of Grain Temperature and Humidity Monitoring System

摘要

This paper describes a control system design of d grain temperature and humidity measurement, and discusses b currently often used temperature sensors and communications. Thermistor and digital temperature sensor are used simultaneously in this system for enhancing the use of the system. The main objective is intelligent detection and control for granary situation of the country's large and medium grain depot Upon completion, the system was tested in a number of grain storage. The result is s atisfactory. The system hardware connection is simple and reliable, while software is convenient for manipulation and friendly interface.
