In the realm of Agri IoT (Agricultural Internet of Things), communication is the cornerstone of efficient data exchange. Utilising a variety of wireless technologies and communication protocols, Agri IoT setups enable seamless transmission of data to centralised systems or cloud platforms for analysis and decision-making.

Understanding these communication methods is crucial for harnessing the full potential of sensors in Agri IoT setups and overcoming challenges associated with connectivity. By leveraging the capabilities of these technologies, Agri IoT revolutionises agricultural practices, enhancing efficiency, productivity, and sustainability.

Here's a closer look at the key points regarding how sensors typically communicate in Agri IoT setups:

IoT Devices

Sensors within the IoT ecosystem utilise a diverse array of protocols. The choice of protocol depends on factors such as power budget, cost constraints, physical size, security considerations, and geographic requirements.

Wireless Communication

Embracing wireless technologies like Wi-Fi, Bluetooth, cellular networks, and more, sensors gain flexibility and mobility, ensuring operation across diverse environments and scenarios.

Communication Protocols

Protocols like MQTT (Message Queuing Telemetry Transport), CoAP (Constrained Application Protocol), and HTTP (Hypertext Transfer Protocol) serve as the backbone for defining rules and formats for data transmission among IoT devices.

Interfacing Categories

Sensors interface directly with microcontrollers through methods like direct digital, direct analog, or protocol-based communications. This interface determines how sensor values are acquired and processed.

Smart Device Connectivity

Connectivity options such as WiFi, Zigbee, Z-Wave, and Bluetooth Low Energy (BLE) facilitate seamless communication among smart devices, enabling them to form interconnected networks for efficient data exchange.

Machine-to-Machine Communication

Sensors collect data and transmit it wirelessly to a network, where it's routed to a server for analysis and action. This machine-to-machine communication streamlines data flow and enables timely decision-making.
