在物聯網的應用中，環境變化的即時監測是很重要的一個領域，這包括空氣品質、大地防災（如土石流預警）、公共建設監控（如橋樑）等，都對監控系統有很大的需求。
不過，這些系統大多是由官方或特定機構主導來設置的，一般民眾並沒法得到這些資訊。相較之下，LASS就是希望從Bottom up建置一套環境感測系統，任何人都可以自己輕易地架設起來，再把所得資訊分享出去；任何想知道某地環境狀況的人，都可以在地圖上看的到。
LASS：Location Aware Sensing system 就是基於公益性、開源建立的環境品質感測網路平台，系統完成度高、門檻低，支援硬體眾多，所有開發組織來自於網路社群的結合，所有程式採公開方式開放原始碼(Open Source)，賦予Maker自行客製各種感測能力，讓更多社群人員參與，並將空氣品質資訊透過網路公開，感測資料採取OPEN DATA的方式開放，讓更多的創新應用及分析能被創造。
LASS是由網路上一位名叫「哈爸」社群達人所發起的開源公益計畫，透過臉書、共筆、Github等方式串連社群和分享成果，目前參與社群不斷成長，此計畫的架構也不斷深化和廣化，並與國際夥伴接軌。
本研究探討自造者(Maker或稱創客)透過網路社群發起公益性開源計畫，利用物聯網時代各種裝置開發板，結合溫溼度、PM2.5感測元件，自己開發環境空氣品質偵測裝置，並以開放硬體(Open Hardware)、開放軟體(Open Software)之開源型式(Open Source)於網路上公開，利用網路臉書串連社群同好，共同開發、共同分享，將資料公開於網路。再發動社群力量將空氣品質偵測裝置，安裝於全國各地，以物聯網技術將感測資料上傳到雲端，再結合雲端大數據技術統計分析環境空氣品質，資料採開放資料(Open Data)架構，可透過訂閱方式將環境資訊分享至社群網站或手機存取。
期盼透過本公益社群空污監測系統網路服務，提供政府環保單位更多空氣品質資訊，並帶動民眾對空氣品質的重視及防制警覺，也可利用自製簡易、開源、親民價格的裝置，向下紮根推廣至各級學校的環境教育及校園空氣品監測，更能透過自己動手做的自造者運動，帶動技職翻轉教育的風潮。

In the application of IoT, real-time monitoring on environmental change is an essential domain, including the air quality, public construction monitoring (e.g. bridges), and the mitigation of mud flow and instability sliding (e.g. mud-sliding pre-warning), all of which is extreme demands onto monitoring system.
These systems are, nevertheless, set and dominated by official authorities or specific institutions, which means, the general public may not be able to obtain these information. In comparison, LASS is expecting to establish a set of environmental sensing system from the bottom; anyone can easily set up (the said system), share the secured information with others who want to know the environmental conditions in a certain area, and let them see the practical status on the map.
LASS: Location Aware Sensing system is a platform of environmental quality-sensing network basic upon commonweal. It has good completeness, low threshold, and multiple supporting hardware; all developing organization is deriving from integration of the internet communities, and all programs are adopting the Open Source, with an open process, allowing makers able to customize various sensing capabilities, not only to have more communities and personnel joining in, but also to disclose the information of air quality onto the network. For the sensing information is using the Open Data for public access, more creative applications and analyses can surely be found or created.
LASS is an open-resource and public-welfare project launched by an internet community pro named as “Ha Pa” who links communities and shares achievements through APPs of Facebook, Github, and Collaborative Writing. To date the joined communities have continuously grown, and the project structure unceasingly deepened and spread to connect with international associations.
This study is to explore the maker who uses the public-welfare and open-resource project (launched by internet community) and the diverse device development boards (in the IoT era), to connect with PM2.5 sensing component (temperature and humidity/ humiture) and air-quality sensing device developed by himself, so as to make public on the network by a method of Open Source (i.e. Open Hardware and Open Software), and to use Facebook to link communities and jointly develop and share the information to make know to the public. The said maker is also launching the community force to install the air-quality sensing device all over the country, using IOT technology to upload the sensed information to Cloud Database, and linking the Cloud Big Data to analyze environmental air quality or gather statistics. The information is adopting the framework of Open Data, and through the approach of subscription, can be sharing the environmental data with community network or accessed by cellular phone.
Through the network system such as the air-pollution monitoring system (public-welfare community), we expect to provide more information about air quality for environmental protecting units of the government, and enhance the populace’s precautious consciousness to value our air quality. We may use the self-made, simple, open-resource, and inexpensive devices to promote them into schools’ environmental education, so as to monitor campus air quality, or through the (self-made) Maker Campaign, to evolve a wave of the flipped education in relation to craftsmanship.
