Automated Oxygen Monitoring System for Hospitals

More than 60 children have died due to lack of oxygen at a hospital in India recently because suppliers' bills have not been paid, thus triggering a massive outcry across the nation. Such similar incidents are taking place across the country, which are not being broadcasted by the media. Owing to such a situation, a revolutionary step has to be taken in order to prevent similar situations in the future. This work discusses the design and implementation of a prototype system, which monitors real time pressure of the oxygen cylinder using a pressure sensor, thereby uploading the data to a web interface using NodeMCU Development Board. An alarm is activated and an email is sent to District Medical Officer in emergency situations, when pressure goes below a critical value. The prototype is developed in such a way that it suits both private and government hospitals, having both centralized and manual oxygen supply system, which can be developed further by automating the oxygen supply system with a closed loop control. Thus, installing an oxygen monitoring system in hospitals would help in reducing further tragedies in hospitals due to lack of oxygen.
