Air Quality Monitor

User Manual V1.0

SAWF-08P is a smart indoor air monitor that supports 2.4GHz Wi-Fi connectivity. It is equipped with a high-definition LCD screen and provides real-time monitoring and display of CO2 concentration as well as temperature and humidity data. By connecting to eWeLink, users can access features such as sound and light alarms, receive air quality improvement suggestions, and view historical records via the app. Additionally, the SAWF-08P is compatible with the Matter ecosystem and supports control through mainstream smart home platforms.

  1. Do not place the device in a highly polluted environment for an extended period to avoid damaging the sensor.
Menu Mode Operation Guide

The menu mode allows for manual calibration of temperature/humidity and switching temperature unit(℃/℉) to improve accuracy.

1. Enter “Menu Mode”

Short-press the “Settings Button”. When the temperature value on the screen starts flashing, it indicates that the device has entered “Menu Mode”.

2.Adjusting Local Display Data

  • Parameter Switching: Short-press the “⇌” button to cycle through the following adjustable parameters in sequence (the currently edited item will flash): Temperature Unit (°C/°F), Humidity Value, Detection Mode (PM2.5/PM10), Temperature Value.
  • Parameter Adjustment:

Short press the “+” or “-” button to:

    • Calibrate temperature and humidity.
    • Switch the temperature unit (℃/℉).

3. Saving Local Modifications

After cycling through all editable items, continue to short-press the “⇌” button to save all modifications and exit “Menu Mode”.

4. Restoring Original Settings

Long-press the “Settings Button” for 10 seconds to clear all locally modified parameters (including temperature value, humidity value, temperature unit, buzzer status, and indicator light status) that were edited in the “Menu Mode”, automatically restoring the device to its factory default state.
