<Energy monitoring 120V>


How to do 

1. Arduino circuit is coupled with the system controller TK-7Y for solar water heater, using an operational amplifier MCP601.

2. To remotely control and monitor the house with a smartphone or tablet using Internet, an Android application was developed using MIT App Inventor 2.

3. The applications are created without writing code in the typical programming languages like java or php.
