Environmntal signals acquisition for an early warning system

This article presents a prototype of environmental signal acquisition system as part of an early warning system, in order to manage possible floods in the Manzanares river basin in Santa Marta, Colombia. The system aims to monitor the soil moisture, rainfall and water level of the site under study, as well as register, store and send these variables in real time through the cellular network. The prototype responds satisfactorily in different test conditions, acquiring the environmental signals and sending remotely to the server. With the performed configuration, sensors show stable output and good response to sudden changes in soil moisture and water level. The acquisition device represents an achievement in terms of low cost hardware integration for risk mitigation due to flooding.
