Introduction

Air Quality Monitor

User Manual V1.0

The SAWF-07P is a smart indoor air quality monitor that supports 2.4GHz Wi-Fi connectivity and is equipped with a high-definition LCD screen. It provides real-time monitoring and displays data on PM2.5, PM10, as well as temperature and humidity. By connecting to eWeLink, users can access features such as sound and light alarms, receive air quality improvement suggestions, and view historical records through the app. Additionally, the SAWF-07P is compatible with the Matter protocol, enabling control via mainstream smart home platforms.

Menu Mode Operation Guide

The menu mode allows for manual calibration of temperature/humidity, switching temperature unit (℃/℉), and toggling PM2.5/PM10 detection to improve accuracy.

1. Enter “Menu Mode”

Short-press the “Settings Button”. When the “temperature unit” 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 (℃/℉).
    • Change the detection mode (PM2.5/PM10).

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.
