Smart Energy Meter Circuit Diagram. The meter count is 100 pulses kwh i e 100 pulses will be required to register one unit. To explain the hardware part of the project i am going to break the circuit into small parts so that it will be easy to understand.
Let s start with the energizing circuit of the system. Connect tx of esp12 rx of arduino. Energy meter or watt hour meter is an electrical instrument that measures the amount of electrical energy used by the consumers.
You can use this solution even for individual appliances to see how much energy they are consuming.
There is one analog pin available in nodemcu esp12 we could use that pin but esp series can take upto 3 3 volts on their pins. Iot internet of things based smart energy meter is a type of energy meter that not only shift the consumer supply form one grid station to another grid station automatically although also calculate the cost of their consumed energy beside this it also gives the intimation to energy supply company during any energy theft condition. You can use this solution even for individual appliances to see how much energy they are consuming. In this project we are building a automated system by using arduino and gsm module you can recharge the electricity balance through this system just by sending a sms.
