An Intelligent Ammonia Sensor Based on Multi-Parameter for Aquaculture

This paper presents an intelligent ammonia sensor based on multi-parameter for aquaculture. Against the ammonia sensors based on the electrochemistry have the problems of complex detection process, high cost of use and maintenance and difficult to realize quick measurement in situ, according to the solution of intelligent sensor, a sensor which integrates Ammonia sensitive, Ammonia ion, pH and temperature probes is developed, using the method of hardware filtering combination with software filtering, solved the problem of output signal weak of ion selective electrode and easy to be interfered. Used multi-sensor data fusion algorithm, and achieved In-situ fast detection of ammonia nitrogen content of water, achieving a quick detection of content of Ammonia and Nitrogen of water in site. This sensor has the characteristics of not requiring the pretreatment of water sample, easy operation, low cost and no pollution.
