Functional Features：

---

The carbon monoxide (CO) concentration detector monitors the concentration of CO gas in the environment in real time through built-in electrochemical or infrared sensors. When the detection value exceeds the preset safety threshold (such as 50ppm), it immediately triggers an audible and visual alarm and can transmit abnormal signals to the monitoring platform through wired communication. Its core function is to provide early warning of the risk of CO poisoning caused by gas leaks, industrial emissions, motor vehicle exhaust, etc., and to link ventilation equipment to automatically open ventilation or cut off gas valves to avoid safety accidents; Simultaneously supporting data storage and historical curve queries, it helps users analyze concentration trends and is commonly used in scenarios such as home kitchens, underground parking lots, industrial workshops, boiler rooms, etc. It is a key equipment to ensure the safety of life and property.
