Quality Monitoring of Water Through Electromagnetic Sensor

摘要

The proposed sensor is designed on the principle of electromagnetic. The sensor structure is capable of generating electromagnetic field; this field is used for sensing contaminations in water. This electromagnetic sensor is a hexagonal-shaped coil surrounding the interdigital capacitor, implemented for monitoring the quality of water. The modelling and simulation results are experimentally tested. The experiments were performed to find out the behaviour characteristics of sensor and also to observe the response of sensor to materials involving air and distilled water. The sensor is capable of differentiating the presence of material. The sensor is tested for phosphate detection. The ammonium dihydrogen phosphate is added to distilled water so that solution of varying phosphate concentration is prepared. The sensor is immersed in the solution and its varying characteristics were obtained. The experimental results and future improvements that will be considered are also incorporated in the paper.
