Rainwater harvesting is one of the oldest practices used to conserve and optimize water resources. Nowadays, there are a lot of public and private facilities which have well-constructed Rainwater Harvesting systems. Still, they usually can't test the quality of the water preserved and has no mechanism to purify the impure content to make them consumable. Many known techniques are primitive and conventional for today's standards. The existing systems don't provide connective features, water treatment or contingency measures to counteract any problem. Usually, these systems are integrated onto blockchains, AI, and some other domains to innovate a new paradigm. Still, the results are generally considered a gimmick and are not helpful for general usage. This lack of compatibility and features with no effective solution needs to be rectified, and a real-world upgrade is required to construct a connected, safe and effortless system is imminent. Therefore, an integrative domain approach is necessary to facilitate the process to tackle these problems, where one of the major domains in technology, such as IoT, is used. The proposed model addresses the issues native to the conventional method and provides a connective environment with water treatment capabilities to establish an effortless and connected Rainwater Harvesting system through IoT with precise results and scopes that help the said challenges.

The banking system in India has more than one lakh plus Automated Teller Machines (ATMs) in our country. According to the Reserve Bank of India (RBI) data, India had 215,039 ATMs at the end of June 2017. The average daily power consumption comes around 5520W in small bank ATM’s. Our proposed system “SEMS (Smart Energy Management System)” is a system to manage the domestic and industrial energy consumption and save electricity usage and money by using IOT (internet of things). It enhances productivity and efficiency, improve real-time decision making, solve critical problems, and create new and innovative experiences. Our proposed idea is the implementation of “Smart Energy Management Solution” at ATMs across India to save the energy, cost and to find out the power tampering in that area. Email Alerts will be sent in case of Power Tampering. Energy Automation improves enhanced usage of energy. Simple analysis reports on current and history of energy usages. Thus our proposed system helps to achieve remarkable savings on energy and money.
