Hoʻohana nui ʻia ka sensor moisture lepo, ʻike ʻia ʻo ka hygrometer lepo, e ana i ka nui o ka wai o ka lepo,
e nānā i ka mākū o ka lepo, ka irrigation mahiʻai, ka mālama ulu lāʻau, etc.
I kēia manawa, ʻo FDR a me TDR ka mea maʻamau i hoʻohana ʻia, ʻo ia hoʻi, ka domain frequency a me ka manawa
domain.Like HENGKO ht-706 seriesmea ʻike maka lepo,
ua ana ia e ka FDR frequency domain method. Ua kūkulu ʻia ka mea ʻike i ka hōʻailona hōʻailona a me ka hoʻonui ʻana,
zero drift a me nā hana uku wela,
a he maʻalahi a maʻalahi ka mea hoʻohana. Ke ana ʻana i ka laulā: 0 ~ 100%, ke ana ʻana i ka pololei: ± 3%.
He liʻiliʻi ka huahana, pale i ka corrosion, pololei a maʻalahi ke ana.
ʻO ka mea hoʻoheheʻe lepo i kēia manawa ʻo ia ka mea ana i ka lepo
nā ʻōnaehana irrigation e kōkua i ka hoʻonohonoho pono ʻana i nā lako wai.Kōkua kēia mika e hoʻemi a hoʻomaikaʻi paha i ka irrigation
no ka ulu maikaʻi loa.
He aha ke kumu oAna ʻana o ka mākū lepo? E ʻoluʻolu e nānā e like me ka hahai ʻana:
1. Ka mana
ʻO ka hoʻohana ʻana i nā waiwai dielectric o ka lepo no ke ana ʻana i ka makū o ka lepo he mea maikaʻi, wikiwiki, maʻalahi a
ʻano hilinaʻi.
No ka capacitive soil moisture sensor me kekahi ʻano geometric, ua like kona capacitance me
ka dielectric mauma waena o nā pou ʻelua o ka mea i ana ʻia. No ka mea, ʻo ka dielectric mau o
ʻoi aku ka nui o ka wai ma mua o nā mea maʻamau,ke mahuahua ka wai o ka lepo, kona dielectric
piʻi mau nō hoʻi e like me ia, a me ka waiwai capacitance i hāʻawi ʻia e ka humidityʻike pū kekahi
piʻi i ka wā ana. Hiki ke ana ʻia ka makū o ka lepo e ka pilina pili ma waena
ka capacitanceo ka mea ike a me ka lepo lepo.Capacitivemea ʻike maka lepoloaʻa nā ʻano o
pololei kiʻekiʻe, ākea ākea, nui nā ʻanoana mea a me ka wikiwiki pane wikiwiki, hiki ke
hoʻohana ʻia i ka nānā ʻana ma ka pūnaewele e ʻike i ka hoʻololi kaomi IJI.
2. Hoʻoholo ʻia ʻo Neutron Moisture
Hoʻokomo ʻia ke kumu neutron i loko o ka lepo e hoʻāʻo ʻia ma o ka paipu ʻimi, a me nā neutrons wikiwiki.
hoʻokuʻi mau ʻia e iame nā mea like ʻole i loko o ka lepo a nalowale ka ikehu, i mea e lohi ai.
I ka wā e hui ai nā neutron wikiwiki me nā ʻātoma hydrogen, nalowale lākou i kaka nui o ka ikehu a me ka maalahi.
No laila, ʻoi aku ka kiʻekiʻe o ka wai o ka lepo, ʻo ia hoʻi, ʻoi aku ka nui o nā mana hydrogen, ʻoi aku ka denser o kaneutron mālie
ao.Ma ke ana ana i ka pilina ma waena o ka neutron lohi ka nui o ke ao a me ka wai o ka lepo, ka wai
mea i loko o ka lepohiki ke ho'oholo 'ia, a 'o ka hewa ana 'ana ma kahi o ± 1%.
hana i nā ana pinepinei nā hohonu like ʻole o ke kūlana kumu, akā ʻo ka hoʻonā kū
ʻilihune o ka mea kani, a ʻo ka hewa ana o ka ʻilinui ma muli o ka maʻalahi o ka hemo ʻana o ka wikiwiki
nā neutrons i ka lewa.No laila, ua hoʻolālā ʻia kahi ʻano mea hana neutron kūikawā, ʻo ia ka palea i ʻole
Hoʻohana ʻia nā ʻano hana no ka calibration.
Loaʻa nā nīnau e like me ka ʻike i nā kikoʻī hou aku no ka Soil Moisture Sensor a me nā mahiʻai ʻē aʻe
ʻO ka mea ʻike ʻike ,E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēia manawa.
Hiki iā ʻoeE hoʻouna mai iā mākou i ka leka uilaE like me ka hahai pololei ʻana:ka@hengko.com
E hoʻihoʻi mākou me nā hola 24, mahalo no kou hoʻomanawanui!
Ka manawa hoʻouna: Mar-21-2022
