CO2 Sensor


A CO2 sensor for greenhouses monitors the levels of carbon dioxide (CO2) within the growing environment. CO2 is essential for photosynthesis, and maintaining optimal levels can improve plant growth, development, and yield. CO2 sensor work by detecting changes in the amount of CO2 in the air surrounding the plants, typically by measuring changes in the infrared light absorption or conductivity. The sensor data can be used to adjust ventilation or CO2 injection systems to maintain optimal growing conditions. Overall, CO2 sensors are an important tool for horticulturists to optimize plant growth and yield in controlled environments.

AI (Machine Learning)

  • Our AI is constantly analyzing every data point from every sensor. That data is provided as valuable and timely insights about growing conditions that enable you to make better decisions and reduce errors.
  • Can control the entire operation on its own based on the parameters you have set, so you don't have to constantly update and configure all your different growing conditions across your various climate zones and crop areas.
  • Automatically protects your crops by informing you when any devices or sensors have stopped working so you can provide replace the item or resolve the issue.
  • Prevents major errors and oversights by providing warnings and notifications when it determines that conditions are not optimal.
