The AI-2003W 7-in-1 Multi-Sensor Indoor Air Quality Detector is your best air quality solution – with visible figures/display – that intuitively simplifies data reading to aid the improvement of indoor air quality for homes, schools, healthcare institutes, smart buildings and smart city projects. Embedded with multi-sensors for detecting pollutants such as PM2.5, PM10, HCHO, CO2, & TVOC, the AI-2003W lets you understand the pollution levels with a quick-glance OLED display and an intuitive app for real-time data. Its built-in wireless solution allows air quality data transmission over the cloud. SI or building administration department can find ways or patterns to improve air quality through in-depth and historical data analysis. 

Not only operating independently from the ventilation system to provide real-time air quality monitoring, but AI-2003W also works for air improvement in conjunction with an array of different air circulators. It supports Wi-Fi/RS485/BLE/Dry contact interface that can easily connect to air circulators to bring in fresh air when the pollution levels indoors are high. Moreover, with the aforementioned array of interfaces, the AI-2003W can be remotely controlOLED to turn on/off the connected air circulator by an app at the owner's behest.

Sensor-to-the-cloud | State-of-the-art IoT System 

The AI-2003W provides you an intuitive understanding of the indoor air quality where you are located, with a fully comprehensive analysis. 

The AI-2003W indoor air quality system consists of three essential components: it starts from the 7-in-1 multi-sensor to accurately sense temperature, humidity, fine dust (PM2.5 and PM10), carbon dioxide (CO2), total volatile organic compounds (TVOC), formaldehyde (HCHO), and more. Secondly, with a variety of network functions such as Wi-Fi, RS485 and Bluetooth technologies, the real-time data from the AI-2003W can immediately be fed to an air improvement system or transmitted to the cloud for further analysis. Each sensor can check the historical data, such as hourly, daily, weekly, and monthly conditions. 


Beyond Air Quality Monitoring | Infinite Possibilities for A Better Life 

It does not matter if owners choose an “air sensor ready” ventilation system or an independent external air sensor; the chances are that owners will not be fully satisfied in achieving a clean air environment.

Edimax came up with an innovative solution (AI-2003W) that combines the reliability of an external air sensor and versatile integration abilities found in all-in-one systems. This system provides real-time and historical data of the majority of air pollutants found in homes and offices while having the flexibility to integrate with a variety of air improvement equipment in order to quickly improve indoor air qualities. All these innovative functions also make the AI-2003W a real time and budget saver for its users.

Supporting multiple interfaces such as RS485/Bluetooth/Dry contact connections, the AI-2003W is compatible with many types of air circulation systems, such as window installations, ceiling-mount or through-the-wall air circulators, in order to fill rooms with sufficient fresh air. 


Intuitive Design | Effortless Management

The display and user interface of the AI-2003W includes an intuitive OLED display, an intuitive mobile app and a comprehensive web/app cloud management system that provides visual dashboards for greater details. The system can also be customized to meet SI or HVAC project requirements.

With a well placed OLED display, the AI-2003W shows live sensing data that can provide vital PM2.5/CO2 and more air quality insights right off the AI-2003W or monitor data of multiple AI-2003W through the powerful App (including specified push notification function).
The AI-2003W is not only designed for air quality monitoring, it is also designed with a robust, easy-to-use cloud management system for SI partners and HVAC operators by incorporating Edimax’s operational experiences and cloud technologies in the IoT sector. These include data visualization, user identification, device tracking/ranking, working device analysis and report, historical trend analysis, and more value-added services. The AI-2003W solution will help owners build a powerful indoor air quality improvement system, quickly and with quality service.

All the data collected from the mobile App or the web management system is synchronized through a secure cloud computing (EdiGreen Cloud) for 24/7 real-time observation and remote management.


Elegant yet Practical Design 

Built-in 7 sensor components (PM2.5, PM10, TVOC, CO2, HCHO, temperature, and humidity), Wi-Fi antennas, air quality data display, and other innovative functions, the AI-2003W maintains a compact and low-key appeal in a silver color tone. Thanks to Edimax innovative ID design, the AI-2003W air quality detector fits in any modern homes, offices, or professional healthcare institutions. Its stand/wall- mount design makes installation quick and easy.

PM2.5 / PM10 Sensor

Airborne particles affect our respiratory system every day. PM2.5 (particles less than 2.5 micrometers in diameter) fine particles can penetrate deep into our lungs and cause irreversible damages. The EdiGeen Home PM2.5/PM10 sensor uses a laser scattering method with a uniquely-designed airflow chamber that has the ability to calculate the concentration of near microscopic particles, such as PM2.5.

CO2 Sensor

CO2 (Carbon Dioxide) is an often-overlooked killer. The embedded CO2 sensor lets the AI-2003W accurately monitor the concentration of CO2, which is odorless, tasteless and colorless. Knowing CO2 concentration helps people respond to indoor air circulation problems and thus leading to a better air quality environment.

TVOC Sensor

TVOC (Total Volatile Organic Compound) or VOCs refer to thousands of organic chemicals. They come from household paint, furnishing, cleaning supplies and many other building materials. The AI-2003W shows the level of TVOC via its color OLED and mobile app.

HCHO Sensor

Formaldehyde (HCHO) can be found in various forms and are used in many furniture and household product manufacturing processes. People who are exposed to HCHO (such as from air diffusion) can experience symptoms such as immediate discomfort and an increased chance of developing cancer. Fitted with a built-in HCHO detector, the AI-2003W can detect real-time formaldehyde concentration in order to help people determine the best course of action to reduce the harming effect.

Temperature and Humidity Sensor

The sensors can monitor and display real-time environmental temperature and humidity data. Moreover, they also provide recent changes and historical information. Track your indoor air quality and create the most comfortable living environment possible.
