Medição de Temperatura e Nível do Lençol Freático Utilizando Rede de Sensores Sem Fio

Abstract

This paper presents the development of a client node in wireless sensor network that performs the acquisition of temperature and level of groundwater. The network node was developed employing a routable XBeePro module, a temperature sensor LM35, a pressure sensor MPX5700DP and a microcontroller ATmega8. The system is able to monitor changes in the level of groundwater can be adapted for use in rivers and lakes for the issuance of alert for possible flooding. The network node operates autonomously and can be installed in locations with difficult access; it has autonomy to operate for long periods of time. The information obtained by the sensor node is sent to software installed on a portable microcomputer. This remote monitoring system will allow researchers to examine climate change in regions difficult to access through an online system.
