With the increasing prevalence of private vehicles and underground parking garages, carbon monoxide poisoning incidents are frequently reported in the news. In recent years, national and local governments have attached great importance to CO monitoring in underground parking garages.

    Carbon monoxide inhalation is extremely harmful to the human body. It combines with hemoglobin to form carboxyhemoglobin, leading to oxygen deficiency. Common symptoms of carbon monoxide poisoning include headache, nausea, vomiting, dizziness, fatigue, and weakness. Exposure to high concentrations of carbon monoxide can severely damage the heart and central nervous system, and even cause death.

    Carbon monoxide (CO) in underground parking garages primarily originates from car engines. When engines idle, incomplete combustion of gasoline produces exhaust fumes containing high levels of CO.

    Underground parking lots are enclosed environments with frequent vehicle traffic, making it difficult for exhaust fumes to dissipate. This leads to a buildup of CO gas, resulting in a pungent odor that can harm human health. Therefore, underground parking garages and parking lots should be equipped with ventilation systems to replace the CO with fresh air.

    The main purposes of installing a carbon monoxide (CMO) monitoring system in underground parking garages are twofold:

    1. To ensure that the CMO concentration in the garage remains below hazardous levels through regular ventilation, a safety consideration.

    2. To optimize ventilation based on the CMO concentration in the underground garage, avoiding energy waste caused by excessive ventilation frequency, a conservation consideration.

    The underground parking garage CMO detection and alarm system is designed with gas detection equipment tailored to different parking garage sizes and fire compartment numbers. Its core component—a carbon monoxide sensor—comprehensively detects the CMO concentration in the underground garage. When the CMO concentration exceeds the preset alarm value, it automatically triggers an alarm and activates the exhaust system for air replacement.

MQ-E2-CO-φ20 Electrochemical CO Sensor

    Our Tensensor's MQ-E2-CO is designed to detection the CO gas in the underground parking garages, besides CO, underground parking garages also contain other harmful gases such as nitrogen oxides and particulate matter (PM2.5/PM10). Appropriate sensors can be added to detect multiple parameters based on actual needs. For more sensor solutions, please contact us:
