Installation

Digital IAQ sensor installation

Open the transmitter by pressing the cover button under the back cover of the transmitter (as shown in Fig. 1 and 2).
Follow the wiring diagram to complete the electrical connections and introduce the cables through the crossing holes.
There are three mounting holes on the back cover of the transmitter, use expansion screws to fix it on the wall (as in Fig. 3), or you can use screws to fix it on top of the 86 box pre-buried on the wall (as in Fig. 4);.
Align and fasten the position of the front cover and the bottom shell to complete the installation (as shown in Figure 5).

FAQ

Q1: What are the typical applications for the digital IAQ sensor? ❯

Indoor Air Quality Monitoring: Common in offices, schools, and residential areas to ensure a healthy environment.
Industrial & Commercial Spaces: Helps in monitoring pollutants from machinery or chemicals.
HVAC Systems: Used in systems to adjust ventilation and filtration based on real-time air quality data.
Environmental Research: Assists in air quality studies, especially in urban planning or pollution control.

Q2: Can this air sensor be used in outdoor environments? ❯

While primarily designed for indoor use, the air quality sensor can be adapted for some outdoor monitoring environments, provided it's protected from extreme weather conditions. Additional protection, such as a weatherproof enclosure, may be required.

Q3: How often does the IAQ sensor need calibration? ❯

The digital IAQ sensor is designed for long-term stability. However, periodic calibration may be needed depending on usage and environmental conditions to maintain accuracy, especially for gases like CO2 and formaldehyde.

More Useful Than I Expected

Honestly bought this out of curiosity, but now I check it every day. It was interesting to see how PM10 and VOC levels changed depending on cooking, ventilation, or even having guests over. The display is clear, and the information actually helps make the house feel healthier. Great product overall.
