Research on the Design of Wireless Sensor System for Soil Temperature Detection Based on Sensor Network

Abstract

The purpose of this paper is to research on the design of wireless sensor system for soil temperature detection based on sensor network. Based on the mathematical model and the state space equation which reflect the actual situation of system, the simulation calculation can be achieved as the basis of choosing control scheme and parameters. The control scheme of temperature control system proposed in the research has good control effects which are optimized by the particle swarm optimization. And the influence of environment temperature is smaller than the normal system. The temperature controller can be in heat preservation condition is not very good, and easy to affected by ambient temperature under the condition of constant temperature control.
