This project deals with Energy measurement and monitoring based on internet of things (IOT). In IOT, we can connect the physical world to the internet. Physical world means,like machines and home appliances which are being used in our day to day life.These tools can be changed into smart things by giving it unique identity in the world. These appliances can be shareing data and communicate with oneanother through web. the appliances can be analyzed and controlledby it anytime and anywhere from the world. The main objective in this project is to measure and control the electric power using IOT, Design and implementation of project is mainly based on NODEMCU using IOT concept. where power is sensed through the pzem module. The signal from this module is processed in nodemcu and communicated to the user’s smart phone through Nodemcu.
