1. Introduction
The SMART SENSOR AS8807 is a portable carbon monoxide (CO) gas detector designed for real-time monitoring of CO concentration. This instrument features an LCD screen for displaying gas concentration readings and incorporates a triple alarm system (sound, light, and vibration) to alert users when CO levels exceed preset thresholds. It is suitable for comprehensive inspection in various environments, including home use and industrial applications.

Setting Alarm Values: Use the Up Key (4) and Down Key (6) to navigate through settings and adjust the low and high alarm thresholds. Press the Confirm Key (7) to save your settings. Refer to the on-screen prompts for detailed navigation.
5. Maintenance
5.1 Battery Care
- Recharge the device when the battery indicator on the LCD shows low power.
- Avoid fully discharging the battery frequently to prolong its lifespan.
- Use only the provided charger or a compatible USB charger.
5.2 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
5.3 Sensor Lifespan
The electrochemical sensor in the AS8807 has an estimated lifespan of 2 years. After this period, the sensor's accuracy may degrade, and replacement or recalibration by a qualified service center may be necessary.
6. Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect to the charger and try again.
- Inaccurate readings: Ensure the sensor area is clear of obstructions. Avoid using the device in extreme temperatures or humidity outside its specified operating range. Consider sensor lifespan if the device is old.
- Alarm not sounding/vibrating: Check if alarm settings are enabled and thresholds are correctly set. Ensure the device is not in a silent mode (if applicable, refer to advanced settings in the full manual).
