Agri IoT :: Prototype 1 : Overview

This article is a part of a series that I’m doing to build agriculture based IoT system.

Objectives :: 

Create a remote sensor node that collects and sends data, a gateway that listens to the sensor and posts the data to Controller. The whole setup should be cost effective and at the same time should work to illustrate the concept. The idea is to have a Controller in intranet which can be used as a management platform for sensors deployed in a local area.

Components ::

Sensor node :  Arduino nano with soil sensor and nrf24l01+
Gateway : Nodemuc with nrf24l01+
Controller : Debian pc with OpenHab2 as controller software

Details :: 

Sensor node communicates with Gateway using RF network and Gateway posts the data to controller through local wifi network using MQTT protocol. Controller has a Mosquito broker which assists in communication between Gateway and Openhab2 software.
