Real-Time Electricity, Water, Gas, bill Monitoring 

This IoT project is called as Energy Meter, where it measures 3 things, namely electricity, water flow and Gas flow.

Working:

    

        All the components are connected as shown in the above fig. We first supply the power to the system, OLED screen is turned on with all the values set as Zero initially. Then in the first test, air flow sensor is activated by blowing through it. The turbines run inside the sensor when the air is blown and the data is displayed on the OLED screen. All the calculations are embedded in Arduino, so the processing part will be carried out by Arduino.

        Similarly, other two sensors are tested in the same way. For water sensor, we use water to turn the turbine inside the sensor, while the Electricity is tested with the help of 9V battery. so when the sensors run, it indicates with the color green when its running, and the data gets converted and the value is displayed on the OLED screen. 

        This data can also be viewed by our android app which shows the values of the output generated from the main unit.

Features:

• All the calculations are done in real-time and sent to your phone.
• The system sends you warning messages for paying your bill.
• If the bill is not paid, then the system shuts the flow completely.
• Only after paying the bill will you be able to reactivated the system.
