According to the principle of gases and infrared detection, a research of nodes control system which is based on wireless sensor network is proposed. The specific design and the operating principle of this system are described. What is more, details of the various parts of system , including gas detecting circuit, infrared detecting circuit, alarming circuit, signal encoding circuit, high-frequency signal generating and transmitting circuit and signal demodulating, decoding circuit, are given. Finally, experimental results were analyzed, and it did well in aspects of wireless transmission range, interference immunity and response sensitivity. This system processed wide range of utility value and had high social and economic benefits.
