Carbon Monoxide Detector MOES WSS-CO-EU-MS Wi‑Fi 230V AC

MOES WSS-CO-EU-MS is a Wi‑Fi enabled carbon monoxide detector designed for 230 V AC mains. It uses a high-performance electrochemical sensor to continuously monitor ambient CO levels and provides both local audible/visual alarms and remote notifications via a cloud-connected app. The device also offers relay output and a 12 V solenoid valve control output for integration with ventilation or shut-off systems.

Advantages

The detector combines an electrochemical sensor with 2.4 GHz Wi‑Fi connectivity to deliver stable, sensitive CO detection and remote alerting. It provides a built-in 85 dB alarm at 1 m, relay output (NC) and a dedicated 12 V solenoid valve control for automatic control of connected equipment. The unit supports simple app-based notifications through common platforms and includes test/mute controls for easy local operation.

Suitable for

• Private homes — bedrooms and living areas
• Multi-storey residential buildings — bedrooms and basements
• Small businesses with indoor gas appliances or heating systems
• Integration with ventilation or gas shut-off systems using relay/solenoid outputs

When it may not be suitable

This detector is intended specifically for carbon monoxide (CO) detection and will not detect combustible gases such as methane, propane or butane. It is not recommended for installation in very dusty, greasy, or otherwise contaminated environments where the sensor may be damaged or give false readings. Avoid placing the unit inside garages, directly in kitchens or boiler rooms where nuisance alarms are more likely.

Key specifications

• Power supply: 110–230 VAC, 50 Hz
• Standby power consumption: 1.5 W
• Alarm volume: 85 dB at 1 m
• Alarm thresholds and response times: 30 ppm (alarm within 2 min), 50 ppm (alarm within 60–90 min), 100 ppm (alarm within 10–40 min), 300 ppm (alarm within 3 min)
• Alarm output: Relay output (normally closed)
• Control output: 12 V solenoid valve output
• Wireless: 2.4 GHz Wi‑Fi (802.11 b/g/n)
• Controls: Test/Mute button
• Operating temperature: -10 to 50 °C
• Operating humidity: 10%–95% RH

How to use

Install the detector on a wall or ceiling near bedrooms or living areas where occupants sleep, and within hearing distance of the alarm. Connect the unit to the local 2.4 GHz Wi‑Fi network and configure notifications in the compatible app (Tuya / Smart Life). Use the test/mute button to check alarm function and silence nuisance alarms temporarily. If integrated with a solenoid valve or external control equipment, wire the relay and 12 V output according to the installer instructions and local electrical codes.

What to consider before purchase

• Device detects only carbon monoxide (CO); it does not detect combustible gases like methane, propane, or butane
• Requires 2.4 GHz Wi‑Fi network and smartphone app for remote notifications
• Not intended for very dirty, dusty, greasy, or corrosive environments
• Placement should ensure alarm audibility while avoiding direct installation in kitchens, garages or boiler rooms

Usage recommendations

Clean the detector monthly using a household vacuum and soft brush. Do not use detergents or solvents on the unit and avoid spraying aerosols on or near the device. If the alarm sounds, shut off gas supply if applicable, ventilate the area by opening windows and follow emergency procedures.
