In this paper we presented a prototype for storing and accessing electricity usage details in cloud using IoT energy meter. Proposed system used energy meter with microcontroller to monitor electricity usage and transmits energy consumed details and cost to server. Users check hourly or daily usage of electricity and their cost online using simple web application. Prototype is experimented to check the electricity consumption details of a class room for five days. Based on Tamil Nadu government electricity board tariff rate for private educational institutions, seven rupees fifty paisa is set as per unit cost for energy used. Results show proposed prototype is effective in monitoring, storing, and accessing electricity usage details in cloud. Energy consumed details and their cost is frequently updated to server and user can access their hourly or daily electricity usage details along with cost in cloud. Proposed system reduces human intervention in monitoring energy meter readings and can save significant amounts of time and money.
