AQD-100 Air Quality display indicates Temperature, humidity and CO2 parameters as well as the clock and calendar. It equipped with not only RS485 Modbus RTU signal output but also three dry contacts (relays) which can be specified as CO2, relative humidity, or temperature to control auxiliary devices for air quality improvement. Meanwhile, a special designed software for AQD series products enables the user to directly set and collect the indoor air quality data in the computer. With data analysis, process control and parameter display all rolled into one, this air quality display is widely deployed in train station, office, school or shopping mall to monitor and keep IEQ data in record for analysis. Meanwhile, its bright seven segment LED display provides a clear air quality indication to passengers, students and office staffs.
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.
The LoRa version AQD-101 Air Quality display wirelessly measures temperature, Relative humidity (RH), PM2.5 and Carbon dioxide, meanwhile, controls the ventilation devices through three dry contacts which could be specified as temperature, RH, PM2.5 or CO2 to optimize the building efficiency. The 4-in-1 air quality display impresses by its huge, bright and clear 7 segments LED display which allows the passengers in the public space to check the air quality, clock, and calendar information immediately. The wireless air quality display equipped with switchable RS485 interface and LoRa interface which could be easily changed by DIP switches. The LoRa frequency of the AQD-101 Air Quality display will follow the Aecl master gateway and will be adjustable under range 862 ~ 932 MHz. Combining four air quality measurements and three dry contacts in one device makes the 4-in-1 air quality display a cost and effective product. Thanks to the multiple functions, the users could achieve the wireless IAQ measurement and device control simultaneously in one device.
