Convenience and flexibility were key considerations for the Arduino IoT Cloud. A major benefit is its ability to program Arduino boards, whereas previously users were required to program them via Arduino Sketch.
“Arduino now offers a complete platform with the MKR family, providing a streamlined way to create local IoT nodes and edge devices. These use a range of connectivity options and compatibility with third-party hardware, gateway, and cloud systems. The Arduino IoT Cloud allows users to manage, configure and connect not only Arduino hardware but also the vast majority of Linux-based devices – truly democratizing IoT development“, commented Massimo Banzi, CTO and Co-founder of Arduino.
To highlight how the Arduino IoT Cloud would work in tandem with the MKR family in a real-world solution, Banzi cites an agricultural example, where low power and alternative connectivity options are essential:
“Suppose we want to build an IoT greenhouse, the goal is to control this greenhouse remotely, i.e., to be able to turn on and off the lights, start the irrigation system, and read and adjust the temperature inside the greenhouse, all without the need for human intervention. The complete system can be automated and controlled using an Arduino MKR WIFI 1010 board along with the Arduino IoT Cloud.”
“Simply attach the relevant sensors (e.g. temperature, light, and humidity sensors), actuators (e.g. irrigation pump), and switches (lights and fan) to the board. Upload the software (Arduino Sketch) and it will be ready in minutes to automatically control the properties of the actuators (e.g. activate the ventilation fans when there is too much humidity in the greenhouse) via a simple web interface.”
“The properties are stored in the Arduino IoT Cloud and can be remotely changed from there without the need to visit the greenhouse. Once this is all in place, the system will wait for events and react to them as necessary – perfectly controlling the environment within the greenhouse. It’s even possible to take this automation one step further, as we’ve seen a solution developed based on Arduino to establish and indicate when the fruit is perfectly ripe for harvest on a commercial farm.”
The Arduino IoT Cloud was designed with security in mind, from product development through its entire life cycle, enabling users to securely provision, connect and authenticate devices to the IoT Cloud while they are deployed in the wild, and ensuring all data transmitted between the device and Arduino’s cloud is confidential and tamper-proof.
Client authentication (X.509 certificates) is adopted for asymmetric-key based authentication, while Transport Layer Security (TLS) is used for securing all traffic to and from IoT Cloud. There is also a way to use webhooks to let the Arduino Things interact with other services like IFTT, Google Spreadsheet, and Zapier.
