4.1 Display and Indicators
Image: The monitor's 3.5-inch LCD screen provides a clear, color-coded display of all measurements.
The monitor features a 3.5-inch LCD screen that displays all measured parameters simultaneously. Readings include CO2 (in ppm), TVOC (in mg/m³), HCHO (in mg/m³), temperature (in °F or °C), and relative humidity (in %). Battery status and air quality level indicators are also visible.
4.2 Physical Design
Image: The monitor features an anti-slip bottom for stable placement and a hook design for versatile mounting options.
The device is designed with ventilation grilles on the sides for optimal air circulation to the sensors. It includes an anti-slip bottom for stable placement on surfaces and a hook design for hanging, offering flexible placement options.
5. Setup
5.1 Charging the Device
Image: The monitor being charged via its USB port.
Before initial use, fully charge the monitor. Connect the provided USB charging cable to the device's charging port and a standard USB power adapter (not included). A full charge takes approximately 2.5 hours and provides 6 to 8 hours of operation. The device can be used while charging.
5.2 Powering On/Off
- To power on, press and hold the power button until the display illuminates.
- To power off, press and hold the power button until the display turns off.
6. Operation
6.1 Understanding the Display
The monitor's colorful display provides real-time readings for:
- CO2 (Carbon Dioxide): Measured in parts per million (ppm).
- TVOC (Total Volatile Organic Compounds): Measured in milligrams per cubic meter (mg/m³).
- HCHO (Formaldehyde): Measured in milligrams per cubic meter (mg/m³).
- Temperature: Measured in degrees Fahrenheit (°F) or Celsius (°C).
- Humidity: Measured in relative humidity (%).
The display also shows a battery indicator and a color-coded air quality level (GOOD, OK, POOR).
6.2 Smart Alarm Function
The device features a smart alarm system to alert you to changes in air quality:
- GOOD: Air quality is optimal. The indicator will typically be green.
- OK: Air quality is acceptable but warrants attention. The indicator will turn YELLOW, and the device will emit two "Bee--Bee" sounds.
- POOR: Air quality is unhealthy. The indicator will turn RED, and the device will emit two "Bee--Bee--Bee" sounds.
6.3 Calibration
To trigger the calibration function, long press the switch button and release it after hearing two beeps. Refer to the on-screen prompts for further instructions during calibration.
7. Understanding Air Quality Parameters
Image: Common sources of indoor and outdoor air pollutants.
- Carbon Dioxide (CO2): A natural component of the atmosphere, but high indoor levels can indicate poor ventilation and lead to drowsiness or headaches.
- Total Volatile Organic Compounds (TVOC): A group of chemicals that can be emitted from paints, cleaning supplies, furniture, and other household products. High levels can cause irritation and other health issues.
- Formaldehyde (HCHO): A common VOC found in building materials, furniture, and some fabrics. It can cause respiratory and skin irritation.
Air quality can change constantly. For a comprehensive understanding of your environment's air quality, focus on measurements taken over longer periods (e.g., over 60 minutes).
