A brief study this year showed a 100% increase in the price of tomatoes in Africa. Greenworld Co. Ltd, a leading agricultural company in Mauritius, has over 4,000 m2 of greenhouses for the production of tomatoes and pepper and provided Link Valleys team with their expertise.
A greenhouse can be defined as a closed structure that is used to protect the plants from external factors such as climatic conditions, pollution, etc. Basic factors affecting plant growth are indoor air quality, sunlight, the water content in the soil, temperature, humidity, etc.
The LoRaWAN® based sensors, controllers and gateway has helped in bringing solutions to many of the existing practical problems over the years. The sensors used here are soil moisture and electrical conductivity sensor and CO2, barometric pressure, temperature, and humidity sensor.
From the data received, the UG65 gateway automatically controls climate parameters efficiently inside the greenhouse by actuating motors, cooling fans, and sliding plastics respectively according to the required conditions of the plants to achieve maximum growth and yield. For example, if the greenhouse temperature is above 30 degrees Celsius and the luminosity of the sun is above 50,000 lux, then a command will be triggered to close the internal shading of the greenhouse for more scientific environmental monitoring.
