Sustainable Smart Agriculture yokhala ndi Biodegradable Soil Moisture Sensor

Kuchulukirachulukira kwa malo okhala ndi madzi kwalimbikitsa chitukuko cha ulimi wolondola, womwe umagwiritsa ntchito umisiri wozindikira zakutali kuwunika momwe mpweya ndi nthaka zimayendera munthawi yeniyeni kuti zithandizire kukulitsa zokolola.Kukulitsa kukhazikika kwa matekinoloje oterowo ndikofunikira kuti muzitha kuyendetsa bwino chilengedwe ndikuchepetsa ndalama.
Tsopano, mu kafukufuku wofalitsidwa posachedwapa m'magazini ya Advanced Sustainable Systems, ofufuza a ku yunivesite ya Osaka apanga teknoloji yowona chinyezi cha nthaka yopanda zingwe yomwe imatha kuwonongeka kwambiri.Ntchitoyi ndi yofunika kwambiri pothana ndi zovuta zaukadaulo zomwe zatsala paulimi wolondola, monga kutayika bwino kwa zida za sensa zomwe zagwiritsidwa kale ntchito.
Pamene chiwerengero cha anthu padziko lonse chikukwera, kuonjezera zokolola zaulimi ndi kuchepetsa kugwiritsa ntchito nthaka ndi madzi ndikofunikira.Precision Agriculture ikufuna kuthana ndi zosemphana izi pogwiritsa ntchito ma sensa network kusonkhanitsa zidziwitso za chilengedwe kuti chuma chigawidwe moyenera kumunda nthawi ndi komwe zikufunika.
Drones ndi ma satellite amatha kusonkhanitsa zambiri, koma sizoyenera kudziwa chinyezi cha nthaka ndi kuchuluka kwa chinyezi.Kuti deta ikhale yabwino kwambiri, zida zoyezera chinyezi ziyenera kuikidwa pansi pamtunda waukulu.Ngati sensa si biodegradable, iyenera kusonkhanitsidwa kumapeto kwa moyo wake, zomwe zingakhale zogwira ntchito kwambiri komanso zopanda ntchito.Kukwaniritsa magwiridwe antchito amagetsi ndi biodegradability muukadaulo umodzi ndiye cholinga cha ntchito yomwe ilipo.
"Dongosolo lathu limaphatikizapo masensa ambiri, magetsi opanda zingwe, ndi kamera yojambula yotentha kuti asonkhanitse ndi kutumiza chidziwitso ndi malo," akufotokoza motero Takaaki Kasuga, mlembi wamkulu wa phunziroli."Zinthu zomwe zili m'nthaka nthawi zambiri zimakhala zosagwirizana ndi chilengedwe ndipo zimakhala ndi nanopaper.gawo lapansi, zokutira zoteteza phula zachilengedwe, chotenthetsera mpweya ndi waya wokonda malata."
Tekinolojeyi imachokera pa mfundo yakuti mphamvu ya kutengera mphamvu zopanda zingwe ku sensa ikufanana ndi kutentha kwa chotenthetsera cha sensor ndi chinyezi cha nthaka yozungulira.Mwachitsanzo, kukhathamiritsa malo a sensa ndi ngodya pa nthaka yosalala, kuwonjezera chinyezi cha nthaka kuchoka pa 5% kufika pa 30% kumachepetsa kufala kwachangu kuchoka pa ~ 46% mpaka ~ 3%.Kamera yojambula yotentha imajambula zithunzi za derali kuti nthawi imodzi itolere chinyezi cha nthaka ndi deta ya malo a sensor.Kumapeto kwa nyengo yokolola, masensa amatha kukwiriridwa m'nthaka kuti biodegrade.
"Tidajambula bwino madera okhala ndi chinyezi chosakwanira cha nthaka pogwiritsa ntchito masensa 12 m'malo owonetsera 0.4 x 0.6 mita," adatero Kasuga."Chotsatira chake, makina athu amatha kuthana ndi kachulukidwe kakang'ono kamene kamafunikira paulimi wolondola."
Ntchitoyi ili ndi kuthekera kopititsa patsogolo ulimi wolondola m'dziko lomwe likuchulukirachulukira chifukwa chosowa zofunikira.Kukulitsa luso laukadaulo wa ochita kafukufuku pamikhalidwe yomwe si yabwino, monga kusayika bwino kwa sensa ndi ma ngodya otsetsereka pa dothi lolimba komanso zizindikiro zina za chilengedwe cha nthaka kupitilira kuchuluka kwa chinyezi cha nthaka, zitha kuchititsa kuti ukadaulo waulimi wapadziko lonse lapansi ugwiritsidwe ntchito. mudzi.
