How it works
Smart farming agriculture kit
eCO-Sense offers an ultra low-cost smart farming kit. Sensors in the soil measure metrics such as temperature, humidity, moisture and carbon dioxide emissions as well as nutrients. The sensors are sustainably powered using a biophotovoltaic cell. These cells generate electricity from photosynthetic materials such as vascular plants and can be placed directly in the field making batteries redundant. The data is transmitted wirelessly and stored in a connected cloud platform.
A healthy soil is the key parameter for optimium crop growth and long-term sustainable yields. Our quantitative model optimises the soil around its health. It takes into account the data from the soil sensors and based on the crop type it can recommend ideal irrigation levels. Nutrient concentrations (nitrate, ammonia) are analysed and translated into required fertiliser amounts. Ideal nutrient levels can boost crop output as well as avoiding overuse of fertilisers.
Power source: A biophotovoltaic cell
Typical power sources rely on batteries or solar panels, which are not well suited to operate within agriultural fields.
We use the growth of the plants in order to generate electricity. This can be achieved with a biophotovoltaic cell.
Once illuminated, plants generate protons and electrons through photosynthesis. The electrons can be collected by an electrode (anode) and travel to a connected cathode, generating an electrical current. This electricity powers the soil sensors and wireless transmitter. At the cathode the reverse reactions converts the electrons with oxygen into water and closes the charge cycle.
