Autonomní solární systém pro sledování kvality vody s dálkovým přístupem

Abstract

Water constituents are often event-driven so concentrations and properties vary strongly in time. Due to this, there is a high demand for devices which can get accurate and real time measurements as these changes occur. Current methods of monitoring water quality mostly involve a team of people who collect samples which are later analyzed in a laboratory. This process is time consuming, expensive and has a slow reaction time which may lead to missing out on important changes in the water parameters. This paper describes a prototype solution which is affordable and capable of producing quick and accurate results in real time. This prototype measures the water quality using various sensors which record the pH level, temperature, total dissolved solids, conductivity and changes in the level of water. These sensors are connected to the ESP32 DevKit V4 microcontroller which processes and transmits the data in real time using Wi-Fi to the thinger.io online monitoring dashboard. This dashboard also stores all the data so it can be for analyzing the trends in changes of water quality. In addition to that, this prototype utilizes solar energy harvesting allowing it to be self-sufficiently powered throughout the year.Water constituents are often event-driven so concentrations and properties vary strongly in time.
