Dahua DHI-HY-GC21B-W2(868) wireless carbon monoxide sensor — a reliable solution for protecting residential and commercial premises from an invisible and deadly threat. The high-performance electrochemical CO sensor provides accurate detection of carbon monoxide concentration and rapid response even before the level exceeds the permissible norm. It operates at a frequency of 868 MHz and easily integrates into the Dahua wireless security system without running cables.

Advantages

The electrochemical CO sensor provides high measurement accuracy and a minimum of false triggers
Wireless connection at 868 MHz simplifies installation and allows the sensor to be placed where needed, rather than where a cable reaches
Display of the current CO concentration on the built-in screen — the real value is always visible, not just the alarm status
Low battery alert eliminates the risk of the sensor suddenly shutting off
The mute function allows the signal to be temporarily silenced without resetting the settings
Integration into the Dahua ecosystem provides centralized monitoring and management

Applications

Residential apartments and private houses with gas boilers or water heaters
