Design and implementation of indoor environmental monitoring wireless sensor networks based on JN5139

In order to better meet the demand of monitoring indoor environmental quality in some applications, this paper presents a scheme of design and implementation of indoor environmental monitoring system based on JN5139 SOC. The system takes full advantages of ZigBee technology of JN5139 SOC chip in wireless sensor network design and implementation to realize the hardware design of wireless sensor nodes and construct Mesh-type sensor network using JENNIC ZigBee protocol stack. Based on above design, PC monitoring control terminal is expanded so as to realize the configuration of operation mode of sensor networks and sensor nodes. The test results show that the proposed system realizes the accurate monitoring of indoor environmental quality parameters such as temperature and humidity, density of carbon dioxide.
