ʻEkolu Mahana a me ʻEkolu Humidity Soil Moisture Recorder
1. Hoʻolauna
ʻO ka mea hoʻoheheʻe lepo he mea kiʻekiʻe kiʻekiʻe, kiʻekiʻe-sensitivity sensor e ana i ka wela o ka lepo.ʻO kāna kumu hana, ʻo ke ana ʻana i ka makū o ka lepo ma o FDR (frequency domain method) hiki ke kūlike me ka lepo volumetric moisture content, ʻo ia ke ʻano o ke ana ʻana i ka lepo e kūlike me nā kūlana honua o kēia manawa.Loaʻa i ka transmitter ka hōʻailona loaʻa, zero drift a me nā hana uku wela.He kūpono kēia sensor no nā māla e pono ai ke ana i ka lepo lepo, e like me meteorology, environment, mahiʻai, ululāʻau, mālama wai, uila, etc.
2. Nā hiʻohiʻona
ʻO ka pololei ana kiʻekiʻe, pane wikiwiki a me ka hoʻololi maikaʻi
Me ka mana hoʻohuli pili i ka hana pale
ʻO ka hoʻolei ʻana i ka epoxy resin, hoʻopaʻa maikaʻi a me ka pale ʻana i ka corrosion, hiki ke kanu ʻia i ka lepo no ka manawa lōʻihi.
ʻO ka hoʻolālā liʻiliʻi liʻiliʻi, maʻalahi ke lawe, maʻalahi ka hoʻokomo, hana a mālama.
Hōʻoiaʻiʻo ʻia ka lōʻihi o ke ola ʻana o nā mea hao kila kila.
ʻO ka hana hilinaʻi, liʻiliʻi i ka paʻakai o ka lepo, kūpono no nā ʻano lepo like ʻole
