CO2 sensors for ventilation

With the increased awareness of environmental protection and the emphasis on indoor air quality, heating, ventilation, and air conditioning (HVAC) systems have become a worldwide necessity for monitoring and regulating the environmental conditions of various properties and vehicles, etc. Indoor air quality is a key factor affecting people’s health. Lack of indoor air circulation, depletion of O2 in the environment, and elevated CO2 concentrations exceeding the limit will gradually produce symptoms such as headaches and drowsiness, and severe lung infections may occur. Severe cases may produce lung infections, etc. Even more serious consequences may occur if exposure to poor-quality air is prolonged. Oxygen (O2) sensors and carbon dioxide (CO2) sensors are commonly used in HVAC systems. CO2 gas sensors are usually used to measure the composition of the air in the ventilation unit, and as a device that can monitor the concentration of carbon dioxide in real time, it not only greatly assists in the purification of equipment to improve the quality of the air, but also brings about a new enhancement of the operational efficiency of the HVAC system.
