This paper studies the outcomes of new application on smart phones to solve smoke haze problem in Chiang Rai. In this application, there are three main parts including web server,android application, and users. For the web server, the automatic filter program downloads the hotspot data of only Chiang Rai every five minutes from the Earth Science Data and Information System (ESDIS) of NASA. After that, the web server updates the new hotspot data in the application installed on smart phones. This proposed application is tested between 1 January 2016 and 30 April 2016 by Protected areas regional office 15 of National Park, Wildlife and Plant Conservation Department. If the users receive warning voice from the hotspot monitoring application on their smart phone, they will plan to control fire area in this application for surveying. In surveyed results, this application can show the number of hotspots, geographic location of hotspots, land use map of burned area and 99 percent of detected hotspots are true fire. The top number of hotspots is 322 in Mae Suai district. The average PM10 of Muean Chiang Rai and Mae Sai stations are to 128 μg/m3and 186.74 μg/m3which are higher than the normal AQI (Air Quantity Index of the United States Environment Protection Agency (EPA), 120 μg/m3) in April 2016. Moreover, the maximun PM10is to 317 μg/m3at Mae Sai station. The moderate-resolution imaging spectroradiometer (MODIS) is used to study hotspots in Chiang Rai.
