Implementation of WiFi-based single phase smart meter for Internet of Things (IoT)

With the advent of Internet and computational era, not only opportunity to send and receive data between humans, but also among the devices without human control over it. This is known as Internet of Things (IoTs) concept which can be applied for solving the growing issue of power/energy management. A solution is a cheap and easy to implement and manage energy monitoring system for our daily usage of electric power. In order to overcome the human errors, manual labor and cost reducing in energy consumption with more efficiency for the power management system, in this paper, we focus mainly on IoT's energy monitoring. The proposed design is to implement a very low cost wireless sensor network and protocol for smart energy and web application capable of automatically reading the unit and sending the data automatically for the power users to view their current energy meter reading. By using this system, the users will be aware of the electricity usage in his/her home to reduce the power wastage and cost of consumption. The system consists of a digital energy meter, ESP8266 WiFi module and web applications for management system. The ESP8266 WiFi module will be embedded into the meter and implement the TCP/IP protocol for the communications between the meter and web application. The experimental results show that the proposed system works very well with efficiency, and it is feasible to implement in practical applications for very low cost-build automatic energy meter reading.
