To proper manage water resources a key component is the data acquisition through environmental monitoring. However, the cost of professional sophisticated hydrological monitoring equipment’s may be prohibitive for many locations around the world. This work aimed to develop and test a low-cost data collection platform (PCD-B) to be used to densify the hydrological monitoring network for rainfall, small rivers level and water temperature. Low cost sensors were compared to professional ones and presented an excellent result, with 100% of the tipping bucket rain records, distance sensor recorded correctly 97.3% and the coefficient of determination greater than 0.99 for water and air temperature. The PCD-B was kept active and collecting data over 150 days without serious problems. The low-cost solution parts have, approximately, 9% of the cost of a professional solution.
