Design of Formaldehyde Monitoring System in Wireless Network

The monitoring of indoor formaldehyde and other harmful gases has attracted more and more attention. In this paper, the wireless sensor technology was introduced into the monitoring of formaldehyde gas. The realization of the hardware and software design of wireless sensor nodes, the design of the real-time monitoring software of the host computer, the development of the communication protocol, and finally achieve the goal of the successful operation of indoor formaldehyde concentration monitoring network. The formaldehyde monitoring system mainly consisted of the formaldehyde concentration collection system, the data of the wireless transceiver system and the host computer monitoring system. The system can effectively complete the data acquisition and processing, and can be real-time monitoring of the site.
