Arduino Oplà IoT Kit

Overview

Arduino Oplà IoT Kit allows you to build your next smart project. Ever wanted an automated house? Or a smart garden? Well, now it’s easy with the Arduino IoT Cloud compatible boards. It means: you can connect devices, visualize data, control and share your projects from anywhere in the world. Whether you’re a beginner or a pro, we have a wide range of plans to make sure you get the features you need.

The Oplà IoT Kit allows you to add connectivity to devices around the home or workplace. It comes complete with a set of 8 Internet of Things self assemble projects ready to show you how to turn everyday appliances into ‘smart appliances’ and build custom connected devices that can be controlled with your mobile phone.

  • Remote Controlled Lights – change color, light modes and switch on/off via your mobile
  • Personal Weather Station – record and monitor local weather conditions
  • Home Security Alarm – Detect motions and trigger warnings
  • Solar System Tracker – retrieve data from planets and moons in the Solar System
  • Inventory Control – track goods in & out
  • Smart Garden – monitor and control the environment for your plants
  • Thermostat Control – smart control for heating and cooling systems
  • Thinking About You – send messages between the Oplà and the Arduino IoT Cloud

For more advanced users the kit provides them with the potential to create their own connected devices and IoT applications through the open programmable platform providing the ultimate control.

The Oplà unit acts as the physical interface with the Arduino IoT Cloud providing you with total control at your fingertips via the Arduino IoT Remote app. Configure and manage all the settings via the Arduino IoT Cloud, with easy to create dashboards providing real-time readings from your smart devices around the home or workplace. Adjusting settings, switching devices on/off, watering plants etc is all controllable on the go with the Arduino IoT Remote app or fully automate the set-up then sit back and enjoy!
