Now that you have an understanding of the basics of Arduino for IoT development, let’s take a look at some of the best projects that you can create.

Energy Bill Monitoring

Monitoring your energy bills is now easy with the help of Arduino IoT projects. With a few simple steps, you’ll be able to create an automated system that records and monitors your energy usage and sends data directly to your smartphone or computer.

To start, you’ll need:

  • Arduino Cloud IoT.
  • Arduino Create Agent.
  • Arduino Modbus library
  • Arduino® MKR WiFi 1010 board.
  • Arduino® MKR 485 Shield.
  • Finder Type 7E.64 Energy Meter.
  • Twisted single pair shielded cable.
  • Micro USB cable.

Energy meters are one of the most valuable components in any home monitoring system. They measure the amount of energy consumed by a given appliance or device, such as an air conditioner, refrigerator, oven, etc., and can be used to monitor energy consumption over time. With the right project setup, you can monitor your energy bills in real-time and track how much electricity you’re using throughout the day.

The first thing you need to do is connect an energy meter with the breaker box in your home. Install the meter using an appropriate current transformer, and according to the color convention. Remember, that at this step you will be working with electricity so make sure to use caution.

Next, connect the energy meter and our MKR WiFi 1010 board. The MKR WiFi 1010 board acts as a bridge between the energy meter and our Arduino Cloud IoT. The RS-485 conventions say that the places where the wires go are called A, B and COM. People usually call the TX+/RX+(or D+) terminal B (high for mark) and the TX-/RX-(or D-) terminal A (low for mark).

Now it’s time to install the MKR 485 shield. Connect the red cable to Y terminal and the white cable to Z terminal, the brown cable (COM) must go into ISOGND terminal. In order to achieve half-duplex communication, we must set the second switch OFF (2 to OFF) and third switch ON (3 to ON): The first one does not have a role in this form of communication. Furthermore, the third switch is responsible for setting up termination–a resistor which links both data terminals together and suppresses interferences.

Finally, connect the MKR 485 Shield and the MKR WiFi 1010 board. We will be using a micro USB cable. Now it’s time to connect the energy meter to Arduino Cloud IoT. To do this, we’ll use the Arduino Create Agent.

Once you’re in the Arduino Cloud IoT, add your device and create an account. On your PC, install the Arduino Create Agent and connect the Wi-Fi board to the computer. Use the agent to configure the device and connect it to your Arduino Cloud IoT account. Once you have done this, go to the configure thing page and add the variables to your project. Finally, you need to provide valid credentials for your energy meter and establish a connection.

Now it’s time to write a sketch in order to read data from our energy meter.

The Modbus library already contains functions which allow us to access several types of meters and make measurements more accurate. You can find some sketch ideas online on various Arduino forums.

After uploading your code to the board, you should head to the ‘Dashboard’ and visualize your energy meter data. You can also use it to find out which appliances in your home are consuming the most energy and set up alerts when it reaches a certain level. Proceed to link all the variables you previously added to the dashboard and select ‘Actuate’ if you want to control any of your devices as well

By using the Arduino Cloud IoT, you can now view your energy bills and monitor your data in real-time from anywhere. You can also set up alarms and notifications that alert you when certain thresholds have been reached.

You now have a full-fledged IoT system that not only monitors your energy consumption, but also allows you to remotely control it from anywhere in the world. With this guide, you should be able to create an easy and efficient Arduino IoT project with no prior experience! Good luck on your future projects!

Pushing Data to Google Docs Project

If you want to push data from an Arduino board to a Google Docs spreadsheet, the process is a bit more involved. You will need to create a script that translates your data into something readable by Google Docs and upload it to your Arduino. To do this, you will first need to set up an account with Google and pushingbox.com.

Once you have your account set up, create a google form and a form key. The key is the unique identifier for your form.

Next, go to the pushinbox and log-in using the form factor that you just created. Use the same form key when logging in. To create a custom service, head to My Services and fill out your Google form. Once you submit the response page of your form, simply copy that URL and paste it into the Pushingbox Service URL field. You can give this new service any name you’d like as well as set its method to GET for easy access!

Then, head to the ‘My scenarios’ tab and create a new scenario. In this scenario, you will specify the form key and the response page URL that you just created.

Paste the following into the scenarios field: FORMKEY=$status$&submit=Submit C. Replace the FORMKEY with your own form key.

Finally, click the ‘Add Action’ button and receive your Device ID. Copy this Device ID and remember it for later use in the code.

Speaking of which, now it’s time to code your Arduino board.

EthernetClient client;

void setup()
{
Serial.begin(9600);
Ethernet.begin(mac, ip);
delay(1000);
Serial.println(“connecting…”);
}

void loop(){

// average temp reading for ‘del’ time…………………………………..

for(int j=0; j<del;j++)
{
// Read local temp………………………………….
int chk = DHT11.read(DHT11PIN);
int temp = Fahrenheit(DHT11.temperature);
temp_av=temp_av+temp;
delay(1000);
}

int avtemp=temp_av/(del);
temp_av=0;

// Post to Google Form………………………………………
if (client.connect(server, 80))
{
k=0;
Serial.println(“connected”);
sprintf(postmsg,”GET /pushingbox?devid=%c&status=%d HTTP/1.1″,devid,avtemp);
client.println(postmsg);
client.println(“Host: api.pushingbox.com”);
client.println(“Connection: close”);
client.println();

Serial.println(postmsg);
Serial.println(“Host: api.pushingbox.com”);
Serial.println(“Connection: close”);
Serial.println();

delay(1000);
client.stop();
}
delay(1000);

if (!client.connected())
{
Serial.println();
Serial.println(“disconnecting.”);
client.stop();
k==1;
return;
}

}

double Fahrenheit(double celsius) // Function to convert to Fahrenheit
{
return 1.8 * celsius + 32;
}

Once your code is ready, compile it and upload it onto your board. Then, open up the Google Docs spreadsheet linked to your form and you should see all the data from your Arduino project uploaded in real-time. [2], [3], [4]
