Carbon dioxide sensors are machines that are used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis in green plants and 95% of the dry weight of a crop comes from photosynthesis. Therefore, the use of CO2 sensors to control the concentration also becomes an important factor in crop yield.

Introduction to carbon dioxide sensors.

Vegetables generally require a CO2 concentration of 1000-1500 ppm. Therefore, the CO2 deficit in plastic greenhouses is quite serious and becomes an important factor affecting the yield of vegetables in plastic greenhouses. The installation of carbon dioxide sensors in plastic greenhouses can ensure a timely alarm in case of insufficient carbon dioxide concentration.

The CO2 sensor collects CO2 data in real time, both indoors and outdoors, and reports the collected data to a cloud server for storage and management. Users can view the CO2 data online in real time and the data is more accurate and efficient, thus avoiding major accidents caused by changes in CO2 concentration.

The wireless CO2 sensor transmits data wirelessly. Rain and snow resistant, corrosion resistant, and can be adapted to high temperatures and cold weather. Real-time data collection and uploading to cloud data platform. Unlimited transmission distance in the networked state, so you can view the data on your mobile phone both inside and outside the shed, even in the field.
