- Connect the USB power cable to the DC adapter input port on the side of the device.
- Plug the other end of the USB cable into a compatible 5V DC power adapter or USB port.
- Press the Power On/Off button to turn on the device.
5.2 Wall Mounting
The device is designed for wall mounting to ensure stable and continuous monitoring.
Figure 5.2: Wall Mounting Guide. This image illustrates the use of the drilling guide sticker for precise wall mounting and shows the decibel meter successfully installed on a wall.
- Choose a suitable location on a wall, away from direct heat sources or strong vibrations, for accurate readings.
- Use the provided wall drilling guide sticker to mark the positions for drilling.
- Drill two holes at the marked positions.
- Insert wall anchors (if necessary, depending on wall material) and then the provided screws, leaving a small portion protruding.
- Align the mounting holes on the back of the decibel meter with the screws and slide the device down to secure it.
6. Operating Instructions
6.1 Basic Operation
- Power On/Off: Press the power button (labeled with a circle and vertical line) to turn the device on or off.
- Brightness Adjustment: Use the "Up" (triangle pointing up) and "Down" (triangle pointing down) buttons to increase or decrease the brightness of the LED display.
- Sampling Rate: Press the "M" button to cycle through different sampling rates: Fast, Medium, and Slow. The sampling rate determines how quickly the device updates its readings.
6.2 Understanding the Display
The large LED display shows multiple parameters simultaneously:
Figure 6.1: Temperature and Humidity Display. This image focuses on the temperature and humidity readings, indicating their respective measurement ranges.
- Decibel (dBA): The main large number indicates the current sound pressure level in decibels, A-weighted.
- Temperature (°C): Displays the ambient temperature. The operating temperature range is -10°C to 60°C.
- Humidity (%): Shows the relative ambient humidity. The operating humidity range is 20% to 85% RH.
- Battery Indicator: Located at the top right, shows the current battery level.
6.3 Decibel Level Indicators
The device features visual indicators (emojis) to quickly convey the current sound level status.
Figure 6.2: Decibel Level Indicators. This image illustrates the visual alarm icons that change based on the detected sound level, providing an immediate understanding of the noise environment.
| Decibel Range | Indicator | Description |
|---|---|---|
| Less than 60dB | Green Happy Face | Quiet environment, comfortable sound level. |
| 60dB ~ 75dB | Yellow Neutral Face | Moderate noise level, generally acceptable. |
| 75dB ~ 85dB | Orange Sad Face | Elevated noise level, prolonged exposure may be uncomfortable. |
| More than 85dB | Red Angry Face | High noise level, potentially harmful with prolonged exposure. |
