MOES smart carbon monoxide (CO) detector: electrochemical sensor, 85 dB siren, NC alarm relay for ventilation or a valve, 110–230 V AC power (1.5 W), Wi-Fi notifications in the Smart Life / Tuya app.

Product description

Smart carbon monoxide (CO) detector | sensor | with relay | 1.5W | 110-230VAC | Wi-Fi | Smart Life | TUYA | MOES

The MOES smart carbon monoxide (CO) detector with an electrochemical sensor detects colourless and odourless CO gas, sounds an 85 dB siren and sends a phone notification over Wi-Fi. A built-in relay can control ventilation or a solenoid valve during an alarm.

Key idea:
Carbon monoxide cannot be smelled or seen. A detector near a boiler, fireplace or gas appliance warns with a local siren and a phone notification, while the relay can automatically start ventilation or close a valve.

Sensor
electrochemical CO

Siren
85 dB / 1 m

Relay
NC contact for alarm

Power
110–230 V AC, 1.5 W

How it works

The detector is powered from the 110–230 V AC mains, so it does not depend on battery condition. The electrochemical sensor continuously measures CO concentration in the air.

When the threshold is exceeded, the audible and visual alarm switches on and a notification is sent via Wi-Fi to the Smart Life / Tuya app. Alarm time depends on concentration: the higher, the faster.

The alarm relay (NC contact) can control extract ventilation or a solenoid valve (12 V control). The button is used for testing and muting.

Why choose MOES CO detector?
One device combines a local siren, a phone notification and an automatic action via the relay – protection works even when nobody is home.

Main functions

CO detection – the electrochemical sensor measures concentration continuously.
Local alarm – 85 dB siren and light indication.
Phone notifications – alarm in the Smart Life app.
Relay for automation – ventilation or valve control during an alarm.
Mains power – no batteries to replace.
Test button – periodic function check.

Where is it used?

Boiler rooms with gas or solid fuel boilers
Homes with fireplaces and stoves
Garages
Flats with gas cookers or water heaters
Country houses and summer cottages
Commercial premises with combustion appliances

Use by need

For homeowners.
CO notification even when away from home.

For boiler room owners.
The relay automatically starts ventilation or closes a valve.

For landlords.
Safety monitoring in a rental home.

Practical use

A house with a solid fuel boiler has a MOES CO detector in the boiler room. When CO concentration rises, the siren sounds, a notification arrives on the phone and the relay starts the extract fan.

Pros

Electrochemical CO sensor
Siren, phone notification and relay in one
Mains powered
Integration with Tuya scenes
Test and mute button

Cons / limitations

Requires 230 V supply at the installation spot
Does not detect natural gas or smoke
Notifications need 2.4 GHz Wi-Fi
The sensor has a limited service life – follow the manufacturer's instructions

Safety and installation notes

The detector supplements but does not replace mandatory safety measures and chimney maintenance.
Install according to the manufacturer's instructions – at the specified distance from the combustion appliance.
Electrical connection must be done by a qualified electrician.
Test the detector regularly with the button.
In an alarm, ventilate the room, leave and call for help – 112.

Quick selection guide

CO sensor

85 dB

NC relay

110–230 V AC

Wi-Fi 2.4 GHz

Smart Life

Suitable when you need:

to detect CO near a boiler, fireplace or stove
to get phone notifications
to control ventilation or a valve automatically

Check before use:

that 230 V supply is available at the location
that 2.4 GHz Wi-Fi reaches the location
that the manufacturer's distances to the combustion appliance are respected
that the relay wiring matches the ventilation or valve control

Important reminder: A CO detector does not replace proper chimney and boiler maintenance – in an alarm, ventilate the room immediately and call 112.

FAQ

What does this detector detect?
Carbon monoxide (CO). Natural gas and smoke require separate detectors.

How is it powered?
From 110–230 V AC mains, consuming about 1.5 W in standby.

What is the relay for?
During an alarm, the NC contact can control ventilation or a solenoid valve.

Will I get a phone notification?
Yes, via Wi-Fi to the Smart Life / Tuya Smart app.

How fast does the alarm trigger?
It depends on concentration: e.g. 300 ppm – within a few minutes, 100 ppm – within 10–40 min.

How to test it?
Press the test button – the siren and indication will switch on.
