The intelligent multi-span polycarbonate greenhouse in Bangladesh uses hydroponic system to cultivate tomatoes

The factors such as temperature, humidity, light intensity, soil temperature and moisture content within the greenhouse play a crucial role in the growth of crops in the greenhouse. The greenhouse automation control system is based on PLC and adopts a computer distributed network control structure to automatically adjust and detect real-time parameters such as air temperature, soil temperature, relative humidity, CO2 concentration, soil moisture, light intensity, water flow rate, pH value, and EC value. It creates the best environment for plant growth, making the environment within the greenhouse close to the ideal values envisioned by humans, thus meeting the needs of the growth and development of greenhouse crops. It is applicable to sites for seedling breeding, high-yield planting, and cultivation of rare and precious flowers, etc., to increase the output of greenhouse products and improve labor productivity. It is a successful example of how high-tech achievements serve large-scale modern agriculture.
