The array is composed of four SAW sensors, a wireless communication network module, and a global positioning system (GPS) module. The four SAW sensors of the array are coated with triethanolamine, polyepichlorohydrin, fluoroalcoholpolysiloxane, and L-glutamic acid hydrochloride to detect hydrogen sulfide (H2S), 2-chloroethyl ethyl sulfide (CEES), dimethylmethylphosphonate (DMMP), and ammonia (NH3) at film thicknesses of 50\u2013100 nm. The wireless communication network module consists of an acquisition unit, a wireless control unit, and a microcontroller unit. By means of Zigbee and Lora technologies, the module receives and transmits the collected data to a PC work station in real-time; moreover, the module can control the sensor array\u2019s working mode and monitor the working status. Simultaneously, the testing location is determined by the GPS module integrated into the SAW sensor array. H2S, CEES, DMMP, and NH3 are detected in 300 m at different concentrations. Given the practical future application in environment in the future, the low, safe concentrations of 1.08, 0.59, 0.10, and 5.02 ppm for H2S, CEES, DMMP, and NH3, respectively, are detected at the lowest concentration, and the sensitivities of different sensors of the sensor array are 32.4, 14.9, 78.1 and 22.6 Hz\/ppm, respectively. With the obtained fingerprints and pattern recognition technology, the detected gases can be recognized.<\/jats:p>","DOI":"10.3390\/s18092977","type":"journal-article","created":{"date-parts":[[2018,9,6]],"date-time":"2018-09-06T10:38:38Z","timestamp":1536230318000},"page":"2977","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["A Novel Surface Acoustic Wave Sensor Array Based on Wireless Communication Network"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0494-6915","authenticated-orcid":false,"given":"Yong","family":"Pan","sequence":"first","affiliation":[{"name":"State Key Laboratory of NBC Protection for Civilian, Beijing 102205, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Mu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of NBC Protection for Civilian, Beijing 102205, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bo","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of NBC Protection for Civilian, Beijing 102205, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bingqing","family":"Cao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of NBC Protection for Civilian, Beijing 102205, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Acoustics, Institute of Acoustics, Chinese Academy of Sciences, Beijing 100190, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liu","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of NBC Protection for Civilian, Beijing 102205, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"73","DOI":"10.1016\/j.snb.2008.10.037","article-title":"A new analytical system, based on an acoustic wave sensor for halitosis evaluation","volume":"136","author":"Daniel","year":"2009","journal-title":"Sens.
