Arduino IoT refers to the integration of Arduino micro controllers with Internet of Things (IoT) technologies. It allows you to build connected devices that can collect data from sensors, send it to the cloud, and control devices remotely using the internet.
Key Components of Arduino IoT:
- Arduino Board: Microcontrollers like Arduino Uno, Nano, MKR WiFi 1010, and Arduino IoT-specific boards.
- Arduino IoT Cloud: A platform by Arduino to simplify IoT development, allowing easy device management, data visualization, and remote control.
- Sensors & Actuators: Components like temperature sensors, humidity sensors, relays, and motors that interact with the environment.
- Connectivity Modules: Modules like ESP8266, ESP32, and built-in Wi-Fi or LoRa support on boards such as MKR series.
- Programming: Usually done using the Arduino IDE with C/C++ or through Arduino IoT Cloud’s visual coding tools.
- Communication Protocols: Common protocols include MQTT, HTTP, and WebSockets for data transmission.
Features of Arduino IoT Cloud:
- Device Management: Easily connect and manage multiple Arduino boards.
- Dashboard Creation: Build custom dashboards for data visualization and control.
- Data Logging: Store and analyze sensor data in the cloud.
- Secure Communication: TLS encryption and secure device identification.
Automation: Create automated workflows based on sensor data (e.g., turn off lights when no motion is detected).
