About - Carbon Monoxide Sensor
This industrial carbon monoxide sensor adopts an imported big brand electrochemical carbon monoxide sensor with high measurement accuracy. Carbon monoxide gas is relatively light and generally concentrated on the top. This co2 sensor is wall-mounted, and the installation height can be adjusted. The shell is made of high-strength waterproof and dustproof material, which can work normally in harsh environments. With our free cloud platform, unified monitoring of multiple locations can be realized.
This wall-mounted carbon monoxide sensor has two-measure ranges of 0~1000ppm and 0~2000ppm. It can measure temperature and humidity at the same time and can add an LCD display for real-time display of data. Support customization and secondary development.

FAQ - CO Sensor
Carbon monoxide (CO) is a colorless, odorless, and non-irritating toxic gas primarily produced by the incomplete combustion of fuels. Since it cannot be detected by human senses such as sight, smell, or taste, it poses a significant risk when inhaled. CO rapidly binds with hemoglobin in the blood to form carboxyhemoglobin, which inhibits the blood’s ability to carry oxygen. This can lead to tissue hypoxia. Exposure to low concentrations may cause symptoms such as headaches and nausea, while higher concentrations can result in unconsciousness or even death. The risk is especially high in enclosed or poorly ventilated environments.
In daily life, devices such as gas or liquefied petroleum gas (LPG) water heaters, coal stoves, and charcoal heating equipment can easily emit carbon monoxide (CO). In kitchens, gas stoves may also release small amounts of CO when combustion is incomplete. In the transportation sector, vehicle exhaust is a major source of CO in urban areas. In industrial, facilities such as boiler rooms, smelting furnaces, incinerators, gas plants, and chemical processing areas often rely heavily on carbon-based fuels. Incomplete combustion in these settings can result in significant CO production.
Because carbon monoxide (CO) is imperceptible to human senses, CO poisoning incidents often occur suddenly and with severe consequences. Installing a carbon monoxide sensor is one of the most effective measures for preventing such accidents. These sensors continuously monitor the ambient CO concentration and trigger an alarm when levels exceed safety thresholds, prompting personnel to evacuate and implement emergency measures in a timely manner.
Mainstream carbon monoxide (CO) sensors primarily operate based on electrochemical principles. When CO gas passes through a diffusion membrane into the sensing chamber, it reacts with the electrodes to generate an electric current. The magnitude of this current is directly proportional to the concentration of CO in the environment. This sensing method offers high accuracy, strong stability, and excellent anti-interference performance, making it particularly suitable for high-reliability monitoring scenarios such as underground parking garages and industrial sites.

When an alarm is triggered, the following actions should be taken immediately:
Quickly open doors and windows to ventilate the area.
Evacuate all personnel to a safe outdoor location.
Turn off all suspicious combustion devices or gas sources.
Call emergency services and seek professional assistance.
Wait for the CO concentration to decrease before re-entering the area.
Never underestimate the alarm or attempt to handle the leak source by yourself.
According to the World Health Organization (WHO) and national standards:
The 8-hour average exposure concentration should not exceed 9 ppm.
The 1-hour exposure concentration should not exceed 35 ppm.
When CO concentration reaches 50 ppm or higher, long-term exposure can pose a serious health risk. Industrial or specialized industry standards may be more stringent and should be set according to the specific application scenario.
The installation location of the sensor significantly impacts its detection effectiveness. It is generally recommended to install the sensor 1.5 to 2 meters above the ground, close to combustion equipment or potential leakage sources. Avoid installing the sensor near ventilation openings, air conditioning vents, or in areas with high humidity or heavy oil fumes.
For residential environments, it is recommended to install the sensor between the bedroom and kitchen. In industrial environments, a distributed installation strategy should be employed to ensure comprehensive coverage for monitoring.
