Abstract. A UAV-assisted water quality measurement system (UAMS) was developed for in-situ water quality measurements on surface waters. A custom-built hexacopter was equipped with an open-source electronic sensors platform to collect water quality data. The electronic components of the system were coated with a water-resistant film and assembled with flotation attachments. Water quality measurements were made with open-source multi-probe meter (OSMM) and commercial multi-probe meter (CMM). The parameters measured with the developed system included water temperature, electrical conductivity (EC), dissolved oxygen (DO), and pH. Percent differences between the two sensors for DO, EC, pH, and temperature measurements were 2.1%, 3.43%, 3.76%, and <1%, respectively. The system can be used for rapid water quality measurements with temporal and spatial resolution. The system would be more beneficial for water quality measurements from difficult to access water sources.
