Product Introduction
CM232W is a smart carbon monoxide alarm designed for connected home safety and residential CO monitoring.
Carbon monoxide cannot be seen or smelled, which makes early detection important in everyday indoor spaces. CM232W helps monitor CO concentration through an electrochemical sensor and displays the reading clearly on the LCD screen.
When alarm conditions are reached, the device provides sound and light alerts directly from the alarm body. With Wi-Fi and Bluetooth support, CM232W can also fit into smart home product lines and app-connected safety solutions.
Its compact wall-mounted design, battery-powered structure and long sensor life make it suitable for homes, apartments, rental properties, smart home brands, online retail stores, wholesale distribution and private label projects.
1. Wi-Fi & Bluetooth Connection,Smart connection for modern home safety.
CM232W supports Wi-Fi networking and Bluetooth pairing, making device setup and connected safety management more convenient for smart home users.
2. Real-Time LCD CO Display,See the CO level clearly on the device.
The front LCD screen displays CO concentration in PPM, helping users understand the current device status more directly.
3. Electrochemical CO Sensor,Focused sensing for carbon monoxide detection.
CM232W uses an electrochemical CO sensor, designed for detecting carbon monoxide in ordinary indoor residential environments.
4. Audible and Visual Alarm,A direct warning when attention is needed.
When CO concentration reaches alarm conditions, CM232W gives both sound and light reminders, helping users notice the warning from the device itself.
5. 10-Year Sensor Life,Built for long-term residential use.
With a long sensor life design, CM232W is suitable for home safety product lines, replacement-cycle sales and property safety projects.
