1. Precision Detection with Scientific Alarm Thresholds

The sensor triggers alarms at different CO concentration levels following standard safety logic:

30 PPM: no alarm within 30 days (low safe level, long-term monitoring reminder)
70 PPM: alarm activates after 60–240 minutes
150 PPM: alarm activates after 10–50 minutes
400 PPM: alarm activates after 4–15 minutes
It gives progressive warning before toxic CO builds to lethal levels, helping you evacuate or ventilate in time.

2. Intuitive Visual Status Feedback

LCD Digital Display: shows real-time CO concentration (unit: PPM) directly for you to view gas level at a glance
3 color LED indicators:
- Green (OPERATE): normal working status
- Red (ALARM): dangerous CO concentration detected, alarm triggered
- Yellow (FAULT): device malfunction reminder
Independent TEST button: perform manual system testing regularly to confirm the sensor, speaker and circuitry work properly

3. 85dB Loud Audible Alert

When carbon monoxide exceeds safety limits, the unit outputs piercing 85dB repeated beeping alarms. The loud sound can easily wake sleeping residents and spread across adjacent rooms to ensure everyone receives the hazard warning promptly.
