Prototype of a wireless sensor network for monitoring water quality for recreational use

Abstract:

A prototype network of electronic sensors for water quality monitoring was designed. The Fatima Monitoring Network (RMF) prototype is made up of a data collection and sampling module. The sampling module measures dissolved oxygen, temperature, pH, and turbidity. In this case, the data is sent through the wireless data collection module, where it is stored on a USB stick and Google Drive. The data is analyzed in Labview 2016. The dissolved oxygen sensor has an absolute error of +/-0.05 mg / l, the pH sensor +/-0.08 pH, the temperature and turbidity sensors have a minimum error. Using the repeatability test, it was verified that the data used was homogeneous. Wireless communication tests demonstrated sharpness at 160 meters, meet network design requirements. The RMF is efficient because it obtains reliable data and its implementation requires 50% of the price of specialized equipment.
