In-Situ Water Monitoring Using Portable Sensor

Pathogen screening is very important in water quality monitoring in water quality monitoring, because the presence of dangerous bacteria can seriously endanger human health. There are different methods for in-situ water monitoring. But this system has more advantages when compared to different methods. The advantages of this method are the time taken to find purity of the water is reduced when compared to other methods. Periodic checking is available in this method. The operations which is takes place in this system is completely automatic and thereby reduces manual work. This system consists of a thermoregulation board and impedance measure board. Both boards were connected with the incubation chamber which consist of sample under test which is directly in contact with stainless steel electrodes. The pH, turbidity and temperature of sample under test(SUT) is measured separately by using sensors. GPRS is used to collect data from impedance measure board, pH sensor, turbidity sensor and temperature sensor and sends the information to the user. The input from the waveform generator in the impedance measure board is given to the electrode which is directly contact with sample in the chamber. The resistive and capacitive components of electrode which is directly contact with the sample is calculated by controller and sent to the user by GPRS.
