He aha ka ʻokoʻa ma waena o Proximity Sensor a me Photoelectric Sensor?

I loko o ka honua o ka mīkini a me nā noi ʻoihana, hana nā mea ʻike i ka hana koʻikoʻi i ka ʻimi ʻana i nā mea, ke ana ʻana i nā mamao, a me ka hōʻoia ʻana i ka holo ʻana. ʻElua mau mea ʻike maʻamau i hoʻohana ʻia ʻo ia nā mea ʻike pili a me nā mea ʻike photoelectric. ʻOiai lawelawe lākou i nā kumu like, hana lākou ma nā loina like ʻole a kūpono i nā noi ʻokoʻa. ʻO ka hoʻomaopopo ʻana i kā lākou ʻokoʻa hiki ke kōkua i ke koho ʻana i ka sensor kūpono no kāu mau pono.

 

Nā Mea Nani Pili

 

ʻIke nā mea ʻike pili i ke alo o kahi mea me ka ʻole o ka hoʻopili kino ʻana. Hoʻokaʻawale ʻia lākou i nā ʻano like ʻole e pili ana i kā lākou mau loina hana, e like me ka inductive, capacitive, magnetic, a me nā mea kani ultrasonic.

 

Nā Mea Nani Hoʻokokoke Inductive: Hoʻohana ʻia kēia mau mea ʻike e ʻike i nā mea metala. Hana lākou ma ka hana ʻana i kahi kahua electromagnetic a me ka ʻike ʻana i nā loli i kēia kahua ma muli o ke ʻano o kahi mea metala.

 

Nā Mea Nani Hoʻokiʻekiʻe Capacitive: Hiki i kēia mau mea ʻike ke ʻike i nā mea metala a me nā mea ʻole. Hana lākou ma ka ʻike ʻana i nā loli i ka capacitance i hoʻokumu ʻia e ke alo o ka mea.

 

Nā Mea Nani Hoʻokiʻekiʻe Mākēneki: ʻIke kēia mau mea ʻike i nā kahua mākēneki a hoʻohana mau ʻia no ka ʻike ʻana i ke kūlana o nā mea makeke.

 

Nā Nani Hoʻokiʻekiʻe Ultrasonic: Hoʻohana kēia mau mea ʻike i nā hawewe kani ultrasonic e ʻike i nā mea. He kūpono lākou no ke ana ʻana i ka mamao a me ka ʻike ʻana i kahi ākea o nā mea.

 

Pōmaikaʻi o nā mea ʻike kokoke:

 

ʻIke Hoʻokaʻaʻole: Hiki i nā mea ʻike kokoke ke ʻike i nā mea me ka ʻole o ka pili kino ʻana, e hōʻemi ana i ka ʻaʻahu a me ka waimaka.

 

Paʻa: Paʻa lākou a hiki ke hana ma nā wahi ʻino.

 

Maʻalahi: Hiki ke ʻike i nā ʻano mea ʻike like ʻole o nā ʻano mea like ʻole.

 

Nā Ki‘i Ki‘i Ki‘i

 

Hoʻohana nā mea ʻike kiʻi kiʻi, i ʻike ʻia ʻo opto-isolators, i ka mālamalama no ka ʻike ʻana i ke alo a i ʻole ka ʻole o kahi mea. Aia lākou i kahi emitter (kumu kukui) a me kahi mea hoʻokipa (ʻike kukui). ʻEkolu ʻano nui o nā mea ʻike photoelectric: through-beam, retro-reflective, a diffuse.

 

Nā Nani Kikowaena Kuu: Loaʻa i kēia mau mea ʻike nā ʻāpana emitter a me nā ʻāpana hoʻokipa. ʻIke ka mea ʻike i kahi mea ke hoʻopau ʻia ke kukui uila ma waena o ka mea hoʻopuka a me ka mea hoʻokipa.

 

Nā Nani Hoʻohāhā: Loaʻa i kēia mau mea ʻike ka emitter a me ka mea hoʻokipa i loko o kahi ʻāpana hoʻokahi a hoʻohana i ka mea hoʻomālamalama e hoʻihoʻi i ke kukui i ka mea hoʻokipa. ʻIke ʻia kahi mea ke hoʻopau ʻo ia i ke kukui kukui.

 

Nā Nani Ho'olaha: Loa'a i kēia mau mea 'ike ka emitter a me ka mea ho'okipa ma ka 'āpana ho'okahi. ʻIke ka mea ʻike i kahi mea i ka wā e hōʻike ai ke kukui i hoʻokuʻu ʻia mai ka mea a hoʻi i ka mea hoʻokipa.

 

Nā Pōmaikaʻi o nā Kiʻi Kiʻi Kiʻi:

 

Lōʻihi ʻimi: Hiki i nā mea ʻike kiʻi uila ke ʻike i nā mea ma kahi lōʻihi.

 

Pono Kiʻekiʻe: Hāʻawi lākou i ka ʻike pololei a kūpono i nā noi e koi ana i ka pololei kiʻekiʻe.

 

Maikaʻi: Hiki iā lākou ke ʻike i nā ʻano mea like ʻole a me nā kala.

 

Nā ʻokoʻa koʻikoʻi

 

Manaʻo Hana:

 

Hoʻohana nā mea ʻike pili i nā māla electromagnetic, capacitance, magnetic field, a i ʻole nā ​​hawewe kani ultrasonic.

 

Hoʻohana nā mea ʻike kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi kiʻi e hoʻohana i nā kukui kukui (infrared a i ʻole ke kukui ʻike ʻia).

 

Laulā ʻIke:

 

ʻOi aku ka pōkole o ka ʻike maka ʻana o nā mea ʻike pili, a hiki i kekahi mau kenimika.

 

Hiki i nā mea ʻike kiʻi kiʻi ke ʻike i nā mea ma kahi lōʻihi loa, mai kekahi mau kenimika a i kekahi mau mika.

 

Nānā Mea:

 

He mea kūpono nā mea ʻike pili no ka ʻike ʻana i nā mea metala a me nā mea hao ʻole ma muli o ke ʻano.

 

Hiki i nā mea ʻike kiʻi kiʻi ke ʻike i nā mea a pau me ka nānā ʻole ʻana i nā mea, inā hiki iā ia ke hoʻomālamalama a hoʻopau paha i ka mālamalama.

 

Nā noi:

 

Hoʻohana mau ʻia nā mea ʻike kokoke i ka hana ʻana, ka ʻeke, a me nā ʻoihana kaʻa no ka ʻike kūlana, ʻike mea, a me ka ʻike pae.

 

Hoʻohana nui ʻia nā mea ʻike kiʻi kiʻi kiʻi i ka automation, robotics, a me nā ʻōnaehana palekana no ka ʻike mea, ana mamao, a me nā noi palekana.

 

I ka hopena, he mea koʻikoʻi nā mea ʻike pili a me nā mea ʻike kiʻi kiʻi i nā noi ʻenehana a me ka automation, hāʻawi kēlā me kēia i nā pono kūʻokoʻa e pili ana i kā lākou mau loina hana. ʻOi aku ka maikaʻi o nā mea ʻike kokoke i ka wā pōkole, ka ʻike ikaika o nā mea like ʻole, ʻoiai nā mea ʻike kiʻi kiʻi e hāʻawi i ka ʻike lōʻihi, kiʻekiʻe-pololei kūpono no nā kaiapuni like ʻole. ʻO ka hoʻomaopopo ʻana i kā lākou ʻokoʻa e hōʻoia i ke koho ʻana i ka sensor kūpono no nā noi kikoʻī, hoʻonui i ka pono a me ka hilinaʻi i nā kaʻina hana ʻenehana.
