Chulalongkorn and the PM 2.5 dust laboratory in the LoRaWAN network



Today, February 3, Assoc. Prof. Pissut Pennonkol, Associate Professor of Innovation Strategy and Professor of Ecological Engineering Engineering, Chulalongkorn University said that the Chulalongkorn University of Engineering, which has collaborated with CAT Telecom Public Company Limited (CAT) to install the LoRaWAN communication network for the development of IoT innovation in air quality control I have seen the problems in the area of ​​the Chula which has both hospitals Communities and universities affected by PM 2.5 dust have begun the research of PM 2.5 Sensor for All "to develop a system for measuring and analyzing the formation of small particles PM 2.5 from the application of the body Knowing the innovation of the Internet sensors of things and the use of CAT communication networks The first phase of the prototype test is to install a 20 point sensor surface prototype about 3 kilometers around Chula.

"Dense sensor networks collect data with frequencies and are constantly coming to the CAT cloud server to analyze the data from a team of Big Data Analytics experts who analyze the weather effects. This causes dust, such as wind or rain, which are associated factors and used to create an air model by a specialist to meet the needs of dust and other air pollutants PM 2.5 Including predicting the weather conditions in the area between each point of installation of the sensor, which is the first set of information we have completed and will be a research methodology for air quality testing that can be adapted to suit any area to expand the results to prevent dust contamination in different areas. Then, Chulalongkorn will plan to continue the research along with CAT and TRF to expand into other areas.

Mr. Viрой Tocarrovanvat, Chief Executive Vice President of the Wireless Business Line, Kat said Cat was ready to continue supporting the PM 2.5 Sensor for All project in the next phase. Currently, the LoRAWAN network is installed in 33 provinces and will cover the whole country in the middle of this year. To support the rapid expansion of the Thai Internet of Things in Different Sectors, "IoT Case Case devices are now being used, including more intelligent CAT services. For application of air quality and dust measurement, Smoke Cat collaborates with Chulalongkorn University. In addition to the network, there are CAT engineers, ST Microelectronics and AVANET, which will help with the development of sensors according to the problems in every field, such as Nan, who is interested in a big smoke powder. Or Bangkok, who is interested in fine dust like PM 2.5 "

The PM 2.5 Sensor for All research project is scheduled to open a dialogue and seminar on February 15, 2019 at the Chulalongkorn University's Engineering Faculty, which will lead the associated countries to join the Sensor prototype kit Together with the awareness of the research and the development of social innovation for air quality in the country.
