Water quality is crucial for public health, especially in areas with water scarcity, such as remote islands. Although reliable measuring devices are available, on-site manual testing, tanks, still necessary. In order to determine the of drinking water, a set measurements should be carried out automatically, at regular intervals and without delay, thus ensuring monitoring its suitability. this research work, an integrated low-cost system presented. The proposed consists stations information system. Each station includes microcontroller sensors, installed reservoir, while used capture, store, visualize measurement data. Data transmission over long-range (LoRa) network, providing extensive coverage receiving data from Internet Things (IoT) devices. Additionally, linear non-linear correction factors improve accuracy resulting more way, end users, local authorities or citizens, given possibility immediate on via web.
