Galvanic pH sensor for continuous monitoring of soil parameters in agriculture

Abstract

Abstract The article discusses trends in agriculture development in digitalization direction, substantiates need for monitoring pH level throughout year. The main solutions existing on market at moment are given, as well as need to develop a pH sensor for USKD-Agro hardware and software complex. The article discusses in detail the ongoing physical and chemical processes, on them basis pH level is determined, circuitry solutions used, as well as pH sensor implementation. The article describes the sensor calibration process, methodology and test results.
