A sort of CO2 concentration monitoring system based on energy efficiency for terminal

CO₂ concentration and temperature in terminals will all rise with the increment of passenger flow. As process control system is often a serious delayed system, it brings a big challenge for environmental quality control including CO₂ concentration and temperature regulation systems in terminals. As CO₂ concentration is more sensitive to the passenger flow than temperature, it is an important parameter for improving the efficiency of environmental quality in terminals. In the end, they all reflect the energy consumption. Therefore, a CO₂ concentration monitoring system with solar charging unit and wireless communication module is developed. Experiments showed that the system has advantages in energy conservation, environmental protection, and measurement accuracy.
