The Heiman CO Sensor Zigbee (SKU: 4251295715353) is a high-precision safety device designed to protect your household from carbon monoxide, often referred to as the 'silent killer'. This compact, battery-powered sensor monitors air quality in real-time, detecting dangerous CO concentrations at an early stage to allow for a swift response before levels become life-threatening.

Advanced Detection and Warning System
Equipped with a high-sensitivity electrochemical sensor, the device ensures reliable detection across a range of concentrations. Upon identifying hazardous CO levels, it triggers a powerful 85 dB audible alarm alongside a flashing red LED visual indicator.
