Greenhouse Control

CO2 control | humidity and temperature

What are transducers used for in greenhouses?

A greenhouse enables the cultivation and growing of plants that could not be grown naturally in its location due to the unsuitable climatic conditions. Furthermore, it can accelerate the growth of plants and food. This is achieved by creating a microclimate that promotes optimal growth for each plant. The selective translucent construction creates the glasshouse effect, which warms up the atmosphere in the greenhouse. However, depending on the external climatic conditions, this can lead to temperatures that are harmful to plants, which is why the temperature and humidity must be monitored and regulated with the help of a ventilation system. In addition to humidity and temperature, the CO2 concentration within the microclimate plays a decisive role in plant growth. By absorbing carbon dioxide, water and light, plants produce glucose, which is responsible for plant growth. This process is called photosynthesis. As the plants bind the CO2, the CO2 concentration in the greenhouse decreases and decelerates the growth processes. For this reason, greenhouses are usually fumigated with CO2. To monitor the concentration and control the CO2 fumigation, CO2 transmitters are used that can determine the CO2 level with high accuracy.
