A Temperature and Humidity Monitoring System of Grain Depot Based on WSN

Abstract:

The traditional temperature and humidity monitoring system of grain depot used to realize in wired network which needs to deploy a large number of cables. The maintainability and scalability is poor. We present a solution of monitoring temperature and humidity of grain depot based on wireless sensor network (WSN). The temperature and humidity data acquisition and control node is composed of digital temperature and humidity sensor and RF wireless chip and the main control chip. Based on the Zigbee technology, these nodes construct a WSN in Ad Hoc in order to collect, monitor and control the temperature and humidity in the monitoring area. The convergence node in the WSN will packed acquisition data from other nodes and then transmit them to a remote monitoring host through the GPRS wireless mobile network. By means of the statistical analysis of the real-time data collected, the monitoring host can alarm and feedback control the temperature and humidity of grain depot. The experimental results show that the system has strong scalability, low power consumption and high efficiency.
