Empirical study of Power Supply unit for cooling and Heating system: Medical Refrigeration in rustic and downpour Affected Area

Abstract: Gold mining and Oring involves the science, technology, and business of the discovery of gold, in addition to its removal and sale in the marketplace. This Mining and ring process involves many issues and hazards to the workers of the mines. The health of the workers in the mines were affected by inhaling dust and toxic gas in the Gold mining environment. In this project we've come up with an idea to overcome the above problems. The blood oxygen level of the workers is continuously monitored by using Pulse OxiMeter and detects the abnormalities in pulse, so that the workers are under monitoring and any issues in health can be detected immediately. The emission of toxic gas is detected by a CH4 sensor which is used to detect methane gas, and dilutes the gas so that it won't affect the workers. The toxic gas is diluted by using an exhaust fan which is attached to our set up.
