This section provide tutorials on connecting various arduino device to FAVORIOT IoT. This easy tutorial helps you build a system for turning LED ON and OFF based in the light sensor reading (LDR sensor) and send an email alert. For this, a Arduino able to measure the light is used. In this tutorial you will learn how to:

• Connect an Arduino to FAVORIOT to send data streams using FAVORIOT HTTP REST API.
• Build an Notification system on FAVORIOT by writing Event Rule to send an email.

Components used

• 1 x Arduino Uno.
• 1 x Ethernet Shield.
• 1 x Breadboard
• 1 x Light sensor (LDR)
• 1 x Resistance. Value of 10 KΩ
• 1 x Resistance. Value of 220Ω
• 1 x Led

Arduino is programmed to send a data stream to FAVORIOT depending on the intensity of light.

All the data streams sent by Arduino is stored in FAVORIOT platform.

In addition to storing data, the true power of FAVORIOT is to let you build Apps quickly with a simple rule based on if-else logic. In this scenario, we are going to build a Alert App that sends an email to you in case that Arduino detects the lights are ON or OFF.

The connections in Arduino are extremely simple. Refer to the diagram below.

If you are registered in FAVORIOT, you have a default device already created for you. Go to the right platform on https://platform.favoriot.com and see the device panel to see the devices that are present. Basically, you need the device_developer_id that might be something like defaultDevice@myusername. But if you want, you can create a new device and use it in this example.

Apikey

Now, go to your “account setting” which is available on the top right corner in the dropdown and check your Apikey. It’s a big alphanumeric token like:
“98346673a6377ef1fde2357ebdcb0da582b150b00cabcd5a0d83045425407ab4”.
You need this apikey to complete the example.

From Arduino you have to build a HTTP request and send the data.

HTTP request
POST /streams HTTP/1.1
Host: api.favoriot.com
Accept: application/json
Content-Type: application/json
apiKey: YOUR APIKEY HERE
Content-Length: YOUR CONTENT LENGTH HERE
Connection: close
Data

{ { "device_developer_id": "deviceDefault@FAVORIOT", "data": {"light":"ON"} } }

Alright then now your device must be sending streams when you turn on and turn off the lights.

It’s time to see whether you can view the data on the platform and check if we have new streams. Login to you account on https://platform.favoriot.com and go to data stream tab.

You will see data like this in the data stream tab.

Great! Now as we are receiving data on our platform let’s send an email whenever new data comes. Go to the Rules tab below the data stream tab.

When inside the Rule tab click on Add New Rule button. A form will appear and fill in the details as described:

The rule should be described as follows:

(stream.Light === "ON") || (stream.Light === "OFF")

The syntax should be followed while describing the rule. stream. prefix (adding stream.is required) is followed the data field sent by device which is light in this case (the data sent by the device is temperature then you will write stream.temperature). You can multiple rule using || (OR) && (AND) logical operators.

Now, whenever the data comes to the platform the rule will be triggered and alert will be sent.

Congratulations! you have just created an IoT project from scratch. Now go ahead and let your imagination run wild. Show us what great things you can build.

If you are having trouble with connecting your device to our platform please contact us at support@favoriot.com.

FAVORIOT offered a very affordable pricing plan as shown below:

The Beginner Plan is very suitable for University students who have been assigned or chose IoT project as their Final Year Project. A single device such as Raspberry Pi or Arduino that collects from several connected sensors can stream to the IoT platform. A simple dashboard is provided to visualize the measurements. This plan is also suitable for an individual developer or hobbyist that would like to familiarize with IoT platform, conduct self-learning or participate in IoT Hackathons. At RM 8.33 (or less than USD 2.00) per month, you can become the next Generation-IoT and on your way to be one of the rare talents in the job market today!

The Startup Plan is perfect for Freelancers or SMEs or Startups to provide IoT solution for a medium size project up to 150 devices. In fact, they can also create multiple projects or applications but limited to the total number of 150 devices.

The Business Plan is great for developing big commercial IoT project. It can support up to 300 devices for many smart applications.

However, if a company requires connecting thousands of devices, they may contact/email their customized requirements to sales@favoriot.com
