A Design of Flood Monitoring System with Low Rate Wireless Sensor Network Coordinator with Multi-Network Using Single Processor
This article presents a design and development of a low rate wireless sensor network coordinator controller. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. In this study develops the system for monitoring and flood warning. This research used small embedded micro controller. The system can expand into multi network and work with single processor. This design will reduce components and power assumption. The research use Propeller Chip by Parrallax Inc. This chip contains eight processors inside. All eight processors can perform tasks simultaneously or with coordination from other processors. A designed of system works together with wireless sensor networks. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. Experimental results show that we can use single microcontroller work with multi-network. It can monitor result of network directly from Propeller chip by generating computer monitor signal.

Low Rate Wireless Sensor Network Data Logger with Multi-core Microcontroller
This paper presents the development of a data logger which collects interesting data via low rate wireless sensor network not expensive low power consumed sensor node. The system is wireless and more flexible to expand and substitute sensor nodes by add proper configuration wireless sensor node. System controller uses embedded small multi-code microcontroller Propeller Chip by Parrallax Inc. This chip contains eight processors (Cogs) inside. All eight processors can perform tasks simultaneously or with coordination from other processors. It comprised of Xbee chip to perform wireless sensor network that work with 802.15.4 protocol. Data is collected and stored in Micro SD memory small size and not expensive. It transfer data from data logger to master computer system via wireless network. The experimental results show that we can use single microcontroller based on data logger system small size and flexible. To expand this system with Propeller chip it can monitor data collected by system directly from this chip by generating computer screen monitor signal.
