Sudden Unavailability of Water in Water Tank May Invite COVID-19 Improved Implementation of Low-Cost Internet of Things Solution

The way the COVID-19 circumstance has been advancing is very disturbing over the globe and apparently this battle will be a prolonged one. At least, till the mission for vaccination succeeds, we should figure out how to live safely alongside the infection. Along with all the safety measures we have recently incorporated into our daily lives, the provision of continuous availability of water in a water tank at households, schools, marketplaces, health care facilities, and all other public gathering places is essential for right time self-sanitation and for maintaining hygienic surroundings, which ensures protection from this pandemic. In this work, at first, we explore the important role of continuous water availability in this pandemic lifestyle. Secondly, we provide a brief survey of existing works which are closely related to proposed problem and thirdly, we have prepared an improved model overcoming the maximum limitations of surveyed models and also adding new feature of thought provoking GUI and applied it to a practical case study to demonstrate its need and effectiveness. Proposed model can be adopted immediately in a cost-effective manner, with applicability ranging from 1000 Litre plastic water tank serving a normal house hold to 1000000 Litre overhead water tank serving a small village or a big industry, promoting the continuous availability of water.
