AQD-WM300 (RS485) CO2 Sensor and Air Quality Controller for Integrators

Air quality CO2 sensors can be literally applied to every industry. ZKTeco Europe is releasing AQD-WM300 (RS485), the ideal wall-mounted CO2 Sensor and Indoor Air Quality Controller that features the ability to measure up to four-following key IAQ parameters: PM2.5, CO2, temperature, and humidity.

A demo and communications protocol are available for integration of AQD-WM300 (RS485) Indoor Air Quality Controller with Smart Home and Building Management Networks, thanks to RS485 connectivity.

An ideal solution for system integrators and manufacturers, to create better solutions for their clients in all kinds of application scenarios:

Residential ventilation systems
Business ventilation systems
Industrial ventilation systems

Wall-mounted integrated air quality controller
RS485 communication protocol
Multiple sensors: PM2.5, CO2, temperature, and humidity
