HuiDeonne 4-in-1 CO & Gas Detector with Temp/Humidity Display | Plug-in Alarm for Home & Travel

HuiDeonne 4-in-1 CO & Gas Detector

This compact, plug-in safety companion brings four essential readings into one device. It monitors carbon monoxide, natural gas, temperature, and humidity, delivering real-time data on a bright LCD and sounding a clear alarm when levels rise. Designed for homes, RVs, and travel, it blends reliable sensing with an easy-to-read interface that fits seamlessly into daily life.

What it detects and how it helps

The detector covers CO from 0 to 1000 PPM and combustible gas from 0 to 10,000 PPM. Alarm thresholds are tiered: CO 70 PPM for a Safe Zone, 150 PPM for an Alert Zone, and 400 PPM for a Hazard Zone, with faster alarms at higher levels. For gas, a threshold of 3,000 PPM prompts a quick response. It also reads ambient temperature from -32 to 212°F (0–99°C) and relative humidity from 0 to 99% RH.

• Combustible gases include LNG/LPG, propane, methane, and butane
• Four-in-one coverage reduces the need for multiple devices

UL standards compliance adds assurance of tested performance in common home environments.

Real-time readings at a glance

The built-in LCD displays CO (ppm), combustible gas (ppm), temperature (°F), and humidity (%RH) so you can monitor changes as they happen, helping you interpret ventilation needs and comfort levels.

Smart alerts with sound and light

When levels cross thresholds, you’ll hear a loud alarm (>85 dB) and see a flashing red LED. The dual-alert system provides both acoustic and visual cues, even in busy or noisy rooms.

Energy-smart and portable design

Powered by AC 90V–240V with standby power under 2W, this detector is designed for long-term use in homes, rentals, or while traveling. Its compact, portable form makes relocation between rooms, vans, hotels, or other accommodations straightforward.

Setup tips and what’s in the box

Plug and play: remove the protective film, plug in, and wait for a green light after about 60 seconds. For the most accurate readings at first use, allow a few minutes for humidity and temperature stabilization. Includes 1x detector and 1x User Manual.

Real-life use scenarios

Whether you’re cooking in a kitchen, resting in a bedroom, or staying in an RV, HuiDeonne 4-in-1 keeps you informed with intuitive visuals and immediate alerts. The LCD simplifies monitoring, while the loud alarm and flashing light provide clear warnings across different environments.

Where to use

Ideal for homes, apartments, basements, and outdoor-adjacent spaces, as well as travel in RVs, hotels, ships, or any enclosed area where gas leaks or CO buildup may occur. Its plug-in design supports versatile deployment.
