摘要：

Extended research on the design and development of a smart nitrate sensor for monitoring nitrate concentration in surface and groundwater are reported in this paper. The developed portable sensing system consists of a planar interdigital sensor, associated electronics, instrumentation, and electrochemical impedance spectroscopy based analysis. The system is capable of measuring nitrate concentrations in the range of 0.01-0.5 mg/L in ground and surface water. This paper extends our earlierwork by including a temperature compensation capacity within the sensor. WiFi-based Internet of Things (IoT) has been included, making it a connected sensing system. The system is capable of sending data directly to an IoT-based web server, which will be useful to develop distributed monitoring systems in the future. The developed system has the potential to monitor the impact of industrial, agricultural, or urban activity on water quality, in real time.
