In this paper, a remote submersion warning system based on multi-mode optical fiber(MMF) sensors and a wireless sensor network(WSN) are proposed. To improve the reliability and stability of the sensors, the dual optical fiber sensors combined to the optical coupler are demonstrated. A slave zigbee as a wireless sensor module was used as a platform to monitor and record the signal from the MMF sensors and then transmits these information to a master zigbee wirelessly. The monitoring system running the LabVIEW® software was connected to the internet to support the short message service(SMS) through extensible markup language(XML) web service. No matter where the managers are, they can always receive the real-time remote-monitoring data for safety check.

In this paper, we proposed a zigbee-based sensor-network systems for remote monitoring of a parking area and a ship submersion. The sensor is composed of a set of infrared LED and photo detector. The wireless zigbee was used as a platform to monitor and record the signal from the optical sensors. A zigbee module as a master was connected serially to PC running the Lab VIEW software.
