This research presents the development of a low rate wireless sensor. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. The purpose of this study is to develop the system for monitoring and flood warning. They will work with wireless sensor network (WSN) system. WSN has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them.

This paper presents a low cost wireless sensor network system which is developed to be an alerting system for relatives or caregivers when the elder is immobile for a long period. The alerting signal is sent via the Internet link and a mobile phone. Remote transducers capture input signal from the mobility subject. If the target subject has immobilized behavior for long period which is analyzed abnormal condition the system will send the alerting messages to a selected mobile phone or Internet link. After detection of motionless elder from the set–point periods the system immediately distributes messages via SMS on the mobile network and a server to warn a relative or a caregiver with the image option to send. The sensor modules have ease-ofinstallation with coverage area nearly 3 square meters 80 % of detection level suitable for a small room and a bathroom

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.

It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. When sensor node is not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode
