Carbon monoxide is the silent threat in your home. You cannot see it, smell it, or taste it. The YHOCO CO Detector with Digital Display solves that problem with clear, immediate information. The 3-digit LCD screen shows you the exact CO concentration in parts per million. That matters because knowing the number tells you if the situation is stable or worsening. This is a practical safety upgrade for anyone who wants more than a generic alarm that only screams when it is too late.

The sensitivity ratings are what make this unit trustworthy. At 70ppm, the alarm will sound between 60 to 240 minutes. At 150ppm, it triggers in 10 to 50 minutes. At 400ppm, you get a warning in 4 to 15 minutes. These response times match industry standards for giving you enough time to react. The 85dB alarm is loud enough to wake you from sleep at one meter. The standby current is under 50μA, meaning the battery-powered design will last a long time without frequent replacements. The LED indicators are simple: a green flash every 30 seconds in standby, and red flashes with chirping every 5 seconds during an alarm.

This two-pack covers the essential spots in your home. Place one near the bedrooms and one near the furnace or garage. The white casing blends into any room without looking like a piece of medical equipment. The only real limitation is the lack of smart home connectivity. There is no Wi-Fi or app integration here. That is fine for a straightforward, reliable detector. It does one job and does it well without complexity. For the price of two units, you get peace of mind backed by clear data and a loud, unmistakable alarm.
