This study applies wireless sensor network (WSN) techniques to monitor the sea temperature, water quality and micro climate of ocean condition in Penghu waters as well as the aquaculture tanks in Aquatic Germplasm Bank of Fisheries Research Institute. Results are summarized as follows:
1. Two bottom-anchored monitoring stations had been constructed at the north islet (Mudou) and the southeast islet (Dongji) islet of Penghu Islands. By using solar-energy, GPRS-communication and sensor technologies, water parameters including temperature, conductivity, salinity and depth can be real-time monitored and analyzed. They provide the water quality information of the northern and southern current with early impacts on the Penghu waters. Nevertheless, aquaculture farmer can receive warning alarms via web, cellphone message and email to take necessary efforts to minimize the damage.
2. Zigbee monitoring system, measuring three parameters of micro climate and seven parameters of water quality, had been improved its hardware and software. It with three end-device/routers and one coordinator installed was deployed in three FRP tanks at the Lukung Aquatic Germplasm Bank for preliminary validation. Furthermore, a brand new stand-alone LCD display with a touch-pad circuit device was designed for water-quality direct measurement.
