Carbon Monoxide Detector TUYA HS082604 Smart Home compatible — carbon monoxide sensor, model HS082604

The TUYA HS082604 carbon monoxide (CO) detector is a standalone sensor for continuous monitoring of indoor CO levels. It uses an electrochemical sensor to detect colorless, odorless CO released by fuel-burning appliances, chimneys, furnaces, gas stoves and other sources. When elevated CO is detected the device sounds an acoustic alarm and flashes LEDs; it also displays CO concentration on an LCD and provides three-color LED status indication. The detector is compatible with TUYA Smart Home systems and supports 2.4 GHz Wi‑Fi for integration and remote notifications.

Advantages

This model employs an electrochemical CO sensor for reliable detection of low concentrations, offers a clear LCD readout of CO levels and three-color LED indicators for quick status checks, and triggers a loud acoustic alarm (>70 dB at 1 m) plus a flashing light for immediate warning. It includes test and mute functions for weekly functional checks and temporary alarm silencing, supports battery operation for installation flexibility, and is TUYA-compatible for smart home integration.

How to use

Install three AAA batteries (not included) and mount the detector on a ceiling or high on a wall in the room to be monitored, following manufacturer spacing and placement guidance relative to fuel-burning appliances. After power-up the device performs self-checks and shows current CO concentration on the LCD. Use the test function weekly to verify correct operation. If the alarm sounds, follow safety procedures: ventilate the area, turn off potential CO sources, and evacuate if necessary. Re-enable monitoring after resolving the source and replacing batteries if indicated.

Usage recommendations

Place the detector at least 1–3 meters from fuel-burning appliances but not too close to vents or very drafty locations. Avoid installing in extremely humid or dusty areas. Replace batteries promptly when low-battery indication appears and test the unit weekly. Integrate the device into your TUYA smart home system using 2.4 GHz Wi‑Fi to receive remote alerts and event logs.
