This invention is to establish a real-time and self-supporting environmental monitoring system using wireless sensor network and solar energy. First, the precipitation volume and groundwater level of monitoring nodes are transported to the gateway by the multi-hop topology of wireless sensor network. Secondly, the gateway transmits the information to a base station via the GPRS or GSM. Finally, the monitoring data are transposed into an established database. The user can inquire about the real-time monitoring information via the internet, and so as to prevent the disaster and to reduce the damage in advance.
