Abstract
A CO2 concentration monitoring system for agricultural greenhouses comprises a CO2 concentration sensor, a CO2 concentration signal processing unit, a wireless transmitting unit, a wireless receiving unit, a microprocessor, and a PC. The CO2 concentration sensor, the CO2 concentration signal processing unit and the wireless transmitting unit are electrically connected in sequence. The wireless receiving unit, the microprocessor and the PC are electrically connected in sequence. The PC is equipped with a piece of CO2 concentration monitoring software. The CO2 concentration sensor acquires the CO2 concentration of an agricultural greenhouse and transmits the CO2 concentration to the CO2 concentration signal processing unit. The CO2 concentration signal processing unit processes a CO2 concentration signal and wirelessly transmits the CO2 concentration signal through the wireless transmitting unit. The wireless receiving unit receives the CO2 concentration signal, which is then processed by the microprocessor and output to the PC. The PC is equipped with the CO2 concentration monitoring software, and monitors the CO2 concentration of the agricultural greenhouse in real time. The CO2 concentration monitoring system for agricultural greenhouses has high real-time performance and high efficiency. Moreover, CO2 concentration signals are transmitted wirelessly, so that no complicated wiring is needed.
