Multi-gas temperature, RH, CO2 and PM2.5 Air Quality Display/Monitor


In order to provide a multifunctional device covers both sensing and control functions, Aecl develop AQD-101 Air Quality display to measure four indoor air quality parameters which are Temperature, Relative humidity (RH), PM2.5 and Carbon dioxide. With huge, bright and clear 7 segments LED display, the air quality monitor can show the air quality, clock, and calendar information to the passengers in the public space. Meanwhile, it also equipped with one RS485 Modbus RTU signal output to send and keep the IEQ data in record. Additionally, three dry contacts which could be specified as optional temperature, RH, PM2.5 or CO2 are equipped in order to optimize the building performance efficiently in the building automation system. When the measurements are higher than the setting level, it can trigger alarm, activate ventilation system or activate ventilation devices in the air-conditioning system to introduce fresh air.

This four in one air quality monitor is widely used in shopping mall, train station, kindergarten and school to provide a general air quality index to the students or consumers. Users can record the data in the Air quality display with Micro SD card 8G,16G or 32G or send the data to the back end platform. To simplified the setting and calibration of the air quality display, we designed a software which users can directly set the maximum and minimum control standard of the Temperature, humidity, PM2.5 and CO2, read the data and calibrate.
