Muulimi wamakono ndi kuyang'anira chilengedwe, masensa a nthaka, monga zida zazikulu, akulandira chidwi chowonjezeka. Amathandizira alimi ndi ochita kafukufuku kupeza zambiri za momwe dothi limagwirira ntchito komanso mankhwala, potero zimakulitsa kukula kwa mbewu ndi kasamalidwe kazinthu. Komabe, mitundu yosiyanasiyana ya masensa a nthaka yomwe ilipo pamsika yasiya anthu ambiri asokonezeka. Zotsatirazi ndi zina zofunika kuziganizira posankha akatswiri odziwa nthaka.
1. Zoyezera magawo
Posankha sensa ya nthaka, choyamba ndikofunika kufotokozera magawo omwe ayenera kuyeza. Zodziwika bwino za dothi ndi izi:
Chinyezi cha nthaka: Chizindikiro chachikulu chomwe chingathandize kudziwa nthawi yothirira.
Kutentha kwa nthaka: Kumakhudza kameredwe ka mbewu ndi kukula kwa mizu.
Phindu la pH: Imakhudza kuyamwa kwa michere ndi zomera.
Mphamvu yamagetsi: Imawonetsa mchere wambiri m'nthaka ndipo imakhudza kukula kwa mbewu.
Posankha masensa, dziwani magawo oyezera ofunikira potengera zosowa za mbewu ndi zolinga za kafukufuku.
2. Mtundu waukadaulo
Pakali pano, pali makamaka mitundu iwiri ya masensa nthaka pa msika
Resistive sensor: Imawonetsa chinyezi cha nthaka poyesa kusintha kwa kukana, imakhala ndi mtengo wochepa, ndipo ndiyoyenera kugwiritsa ntchito pang'ono.
Sensor ya Time-domain Reflectometry (TDR): Imayesa nthawi yofalikira ya mafunde amagetsi munthaka, yokhala ndi kulondola kwambiri komanso kukwanira kwamitundu yosiyanasiyana ya dothi. Ndi yabwino kwa minda yayikulu kapena ntchito zofufuza zasayansi.
Sankhani mtundu woyenera waukadaulo kutengera momwe zinthu ziliri komanso bajeti yanu.
3. Kutumiza kwa Data ndi kugwirizana
Masensa amakono a nthaka nthawi zambiri amakhala ndi mphamvu zotumizira deta ndikuthandizira ma protocol opanda zingwe monga Wi-Fi, Bluetooth kapena LoRa. Ntchitoyi imathandiza ogwiritsa ntchito kuyang'anira nthaka mu nthawi yeniyeni ndikugwirizanitsa deta pamtambo wamtambo kapena pulogalamu ya foni. Musanagule, onetsetsani kuti sensor yosankhidwayo ikugwirizana ndi zida zomwe zilipo kuti zithandizire kugwiritsa ntchito komanso kusanthula deta.
4. Kulondola ndi nthawi yoyankha
Posankha masensa a nthaka, kulondola ndikofunikira kwambiri. Masensa olondola kwambiri amatha kupereka deta yodalirika komanso kuthandiza ogwiritsa ntchito kupanga zisankho zasayansi. Kuonjezera apo, nthawi yoyankhira imakhalanso yofunika kwambiri, makamaka m'malo osintha mofulumira. Zomverera zomwe zimayankha mwachangu zimatha kupereka chidziwitso mwachangu.
5. Mtengo ndi chithandizo pambuyo pa malonda
Mitengo ya masensa a nthaka yamitundu yosiyanasiyana ndi mitundu imasiyana kwambiri. Pamene bajeti ili yochepa, tikulimbikitsidwa kusankha mankhwala omwe ali ndi mtengo wapamwamba. Panthawi imodzimodziyo, chithandizo chabwino chotsatira pambuyo pa malonda ndi ntchito zaumisiri ndizofunikanso pakusankhidwa. Onetsetsani kuti chithandizo chaukadaulo choperekedwa ndi wogulitsa chikhoza kukwaniritsa zofunikira pakugwiritsa ntchito.
Mapeto
Kufunika kosankha sensa yoyenera ya nthaka kuti ipititse patsogolo ntchito zaulimi komanso kuyang'anira chilengedwe ndizodziwikiratu. Pambuyo pomvetsetsa zosowa zanu, mtundu wa teknoloji, kugwirizanitsa deta, kulondola ndi zina, zidzakuthandizani kusankha mwanzeru. Tikuyembekeza kuti chiwerengero chachikulu cha alimi ndi ofufuza asayansi angapeze "othandizira abwino" oyenera pakuwunika nthaka.
Ndi chitukuko chaukadaulo, kugwiritsa ntchito masensa a nthaka kudzafalikira kwambiri, kukulitsa luso laumisiri waulimi ndikulimbikitsa chitukuko chokhazikika.
