He aha ka Passive Sensor?

Ua kapa ʻia hoʻi ka sensor passive he sensor hoʻololi ikehu. E like me ka Internet of Things, ʻaʻole pono ia i ka lako mana waho, ʻo ia hoʻi, he sensor ia ʻaʻole pono e hoʻohana i ka lako mana waho, akā hiki nō hoʻi ke loaʻa ka ikehu ma o ka sensor waho.

Ua ʻike mākou a pau e hiki ke hoʻokaʻawale ʻia nā sensor i nā sensor pā, nā sensor kiʻi, nā sensor mahana, nā sensor neʻe, nā sensor kūlana, nā sensor kinoea, nā sensor kukui a me nā sensor kaomi e like me nā nui kino like ʻole o ka ʻike a me ka ʻike ʻana. No nā sensor passive, ʻo ka ikehu kukui, ka radiation electromagnetic, ka mahana, ka ikehu neʻe kanaka a me ke kumu haʻalulu i ʻike ʻia e nā sensor he mau kumu ikehu hiki.

Ua hoʻomaopopo ʻia hiki ke hoʻokaʻawale ʻia nā sensor passive i ʻekolu mau māhele: optical fiber passive sensor, surface acoustic wave passive sensor a me passive sensor e pili ana i nā mea ikehu.

• Mea ʻike fiber optical

ʻO ke sensor fiber optical kahi ʻano sensor e pili ana i kekahi mau ʻano o ka fiber optical i hoʻomohala ʻia i ka waena o nā makahiki 1970. He mea hana ia e hoʻololi i kahi kūlana i ana ʻia i kahi hōʻailona kukui hiki ke ana ʻia. Loaʻa iā ia ke kumu kukui, sensor, mea ʻike kukui, kaapuni hoʻoponopono hōʻailona a me ka fiber optical.

Loaʻa iā ia nā ʻano o ke kiʻekiʻe o ka ʻike, ke kūpaʻa ikaika o ka hoʻopilikia electromagnetic, ka insulation uila maikaʻi, ka hoʻololi ikaika i ke kaiapuni, ke ana mamao, ka hoʻohana ʻana i ka mana haʻahaʻa, a ke oʻo nei i ka hoʻohana ʻana o ka Pūnaewele o nā mea. No ka laʻana, ʻo ka optical fiber hydrophone kahi ʻano sensor leo e lawe ana i ka optical fiber ma ke ʻano he mea koʻikoʻi, a me ka optical fiber temperature sensor.

• ʻIke Nalu Leo ʻIli

ʻO ka sensor Surface Acoustic Wave (SAW) kahi sensor e hoʻohana ana i kahi mea hana nalu acoustic o luna ma ke ʻano he mea ʻike. Hōʻike ʻia ka ʻike i ana ʻia e ka loli o ka wikiwiki a i ʻole ke alapine (frequency) o ka nalu acoustic o luna i loko o ka mea hana nalu acoustic SURFACE, a ua hoʻololi ʻia i mea ʻike hoʻopuka hōʻailona uila. He sensor paʻakikī ia me kahi ākea o nā sensor. Hoʻokomo nui ia i ka sensor kaomi nalu acoustic o luna, ka sensor mahana nalu acoustic o luna, ka sensor gene biological nalu acoustic o luna, ka sensor kinoea kemika nalu acoustic o luna a me ka sensor akamai, a pēlā aku.

Ma waho aʻe o ke sensor fiber optical passive me ke kiʻekiʻe o ka ʻike, hiki ke ana i ka mamao, nā ʻano o ka hoʻohana ʻana i ka mana haʻahaʻa, hoʻohana nā sensor nalu acoustic surface passive i ka hoʻololi pinepine ʻana o ka wikiwiki o ka Hui, no laila hiki ke pololei loa ka hoʻololi ʻana o ka nānā ʻana i ke ana o waho, i ka manawa like me nā ʻano o ka liʻiliʻi o ka leo, ke kaumaha māmā, ka hoʻohana ʻana i ka mana haʻahaʻa e hiki ai iā ia ke loaʻa nā waiwai thermal a me nā mechanical maikaʻi, a ua alakaʻi i kahi au hou o nā sensor uea ʻole, liʻiliʻi. Hoʻohana nui ʻia ia ma nā kahua substation, kaʻaahi, aerospace a me nā kahua ʻē aʻe.

• Sensor Passive i hoʻokumu ʻia ma nā mea ikehu

ʻO nā sensor passive e pili ana i nā mea ikehu, e like me ka inoa e hōʻike nei, hoʻohana i ka ikehu maʻamau i ke ola e hoʻololi i ka ikehu uila, e like me ka ikehu māmā, ka ikehu wela, ka ikehu mechanical a pēlā aku. ʻO ka sensor passive e pili ana i nā mea ikehu he mau pono o ka laulā ākea, ka hiki ke pale i ke komo ʻana, ka liʻiliʻi o ka hoʻopilikia ʻana i ka mea i ana ʻia, ka ʻike kiʻekiʻe, a hoʻohana nui ʻia i nā kahua ana electromagnetic e like me ke kiʻekiʻe o ka voltage, ka uila, ka ikaika o ke kahua radiation ikaika, ka microwave mana kiʻekiʻe a pēlā aku.

ʻO ka hui pū ʻana o nā Sensor Passive me nā ʻenehana ʻē aʻe

Ma ke kahua o ka Pūnaewele o nā Mea, ua hoʻohana nui ʻia nā sensor passive, a ua paʻi ʻia nā ʻano sensor passive like ʻole. No ka laʻana, ua hānau ʻia nā sensor i hui pū ʻia me NFC, RFID a me wifi, Bluetooth, UWB, 5G a me nā ʻenehana uea ʻole ʻē aʻe. Ma ke ʻano passive, loaʻa i ka sensor ka ikehu mai nā hōʻailona lekiō i ke kaiapuni ma o ka antenna, a mālama ʻia ka ʻikepili sensor i loko o ka hoʻomanaʻo non-volatile, kahi e mālama ʻia ke hāʻawi ʻole ʻia ka mana.

A me nā mea ʻike kaula uila passive textile e pili ana i ka ʻenehana RFID, Hoʻohui ia i ka ʻenehana RFID me nā mea lole e hana i nā lako me ka hana ʻike ʻana i ke ʻano. Hoʻohana ka mea ʻike kaula RFID textile i ke ʻano kamaʻilio a me ka hoʻokomo ʻana o ka ʻenehana tag UHF RFID passive, hilinaʻi i ka ikehu electromagnetic e hana, loaʻa ka hiki ke miniaturize a me ka maʻalahi, a lilo i koho kūpono o nā mea hiki ke hoʻohana ʻia.

I ka hopena

ʻO ka Passive Internet of Things ke kuhikuhi hoʻomohala o ka Internet of Things i ka wā e hiki mai ana. Ma ke ʻano he loulou o ka passive Internet of Things, ʻaʻole i kaupalena ʻia nā koi no nā sensor i ka hoʻohana ʻana i ka mana liʻiliʻi a me ka haʻahaʻa. ʻO ka Passive Internet of Things kekahi kuhikuhi hoʻomohala e pono ke hoʻomohala hou ʻia. Me ka hoʻomau ʻana o ka oʻo a me ka hana hou o ka ʻenehana sensor passive, e ʻoi aku ka laulā o ka hoʻohana ʻana i ka ʻenehana sensor passive.
