Water, the primary source of human existence, vastly occurs in the earth, our home. The major share of water resource comes from ocean and sea which is saline in nature. The remaining constitutes the freshwater or surface water resources on which we depend for our day to day life for domestic uses and consumption. In this context it is very necessary that better quality water ensure for human population and the environmental protection. Among various quality indices, Total Dissolved Solvents are considered as predominant that accounts for hardness and salinity, for the salt organic and inorganic constituents present. The lack of knowledge about the contents prevents common man to use such water or ill treatment of water bodies results in misuse of water resources. The work focuses on an alternative by identifying the solvents present in the water body ensuring to desalinate the particular ionic compound or metal.

The monitoring of a patient can be carried out by continually measuring the vital parameters by using a pulse oximeter. SpO2 (Oxygen saturation) and the heart rate are the certain parameters for the critical patients to be monitored continuously. In this monitoring system, parameters of the patient are monitored by using pulse oximeter having two Light Emitting Diodes (LED’s) with dissimilar wavelengths. Continuous Pain free monitoring is achieved by a non-invasive monitoring procedure. In this paper, the measured values of SpO2 and the heart rate are wirelessly sent to the doctor through Wi-Fi. These measurements provide early caution to the person to avoid the possible problems in the body.
