Farmer Charlie brings connectivity and information to farmers, who receive tailored agronomic data to improve their agricultural practice. Farmer Charlie is based on on-site sensors through which soil data can be detected, gathered, and processed by a dedicated server. Broadband communication allows farmers to receive real-time, localised information on tablet or mobile phone. Farmer Charlie is a low-cost solution, it can be adapted to various crops and to detect soil humidity, pH, temperature, which in turn permit to limit the use of fertilisers, pesticides, and irrigation. These advantages can therefore positively impact the environment, which will benefit from lower carbon emissions, less waste, less pollutants. Farmer Charlie is a climate-friendly, sustainable solutions, which is also going to be tested in least developed countries – especially in remote areas – favouring fair trade and equitable commerce. Broadband dual communication also allows direct contact with farmers and efficient traceability, so that transparency is ensured over the supply chain. Tailored applications can also be hosted by the system, which offers a flexible open platform that can be integrated for multiple aims. Overall, Farmer Charlie can be defined as a micro-agricultural solution that can be exploited on a big scale.
