AQD-WM300 (RS485)

Applications

• Residential ventilation system.

• Business ventilation system

• Industrial ventilation system

Description

AQD-WM300 (RS485) is an indoor air quality controller with screen provides customers with visual indoor air
quality readings, such as PM2.5, CO2, temperature, humidity, etc. It is widely used in residential, commercial and
industrial applications, and can eectively improve air quality and create a healthy, comfortable, ecient,
environmentally friendly, energy-saving living and working environment.

Features

Compatible with embedded and wall-mounted xing methods;
Compatible with push-button and touch-screen operation;
Using standard 86 box size, thickness <24mm;
PM2.5, CO2, temperature and humidity etc., multiple sensors can be optionally selected.

Working Principle

The built-in dust sensor uses the principle of laser scattering technology to detect the indoor PM2.5 mass
concentration in real time (μg/m³).
The built-in carbon dioxide sensor uses the principle of NDIR technology to detect indoor CO2 concentration in
real time (ppm).
The temperature and humidity sensor use capacitor resistance material to detect the indoor temperature
(° C) and humidity (%) in real time.
