PIR vs. ʻO nā kukui ʻo Microwave Sensor Bulkhead: ʻO wai kahi e koho ai?

ʻOi aku ka maikaʻi o nā mea ʻike PIR ma nā wahi i hoʻopaʻa ʻia a i ʻole-paʻa i hiki iā lākou ke ʻike pono i ka wela o ke kino me ke keakea ʻole. Hiki i nā mea ʻike microwave ke ʻike i ka neʻe ʻana ma o kekahi mau pilikia a kūpono i nā wahi nui, ākea, a paʻakikī paha.

Inā makemake ʻoe e pale i ka hoʻoheheʻe ʻia ʻana ma muli o ka -neʻe kanaka ʻole (e like me ka lulu ʻana i nā lālā), e koho i kahi mea ʻike PIR. Inā makemake ʻoe i ka ʻike kiʻekiʻe a me kahi ākea ʻike ākea, ʻoi aku ka maikaʻi o ka mea ʻike microwave.

Ma nā wahi wela loa, hoʻokokoke ka ikaika o ka radiation infrared i ke kino o ke kanaka, e paʻakikī ana i nā mea ʻike PIR ke ʻike i nā loli i ka wela o ke kino, e alakaʻi ana i ka emi ʻana o ka naʻau a i ʻole nā ​​​​ʻike ʻike. Hana pono nā mea ʻike microwave i ka pōʻeleʻele, ka noe, a me nā kaiapuni ʻē aʻe, akā i ka makani a i ʻole ka ua, hiki ke hoʻopilikia ʻia e nā mea liʻiliʻi e neʻe nei e like me nā lau a me nā kulu ua, e hoʻopiʻi hewa ai a i ʻole nā ​​​​alaala.

He ʻano maʻalahi nā mea ʻike PIR a haʻahaʻa i nā kumukūʻai hana, e ʻoi aku ka maʻalahi o nā polokalamu. ʻO kā lākou kumu hana paʻa ka hopena i nā helu haʻahaʻa haʻahaʻa a me nā koi mālama. ʻO ka ʻokoʻa, pili nā mea ʻike microwave i ka ʻenehana paʻakikī a me nā kumukūʻai kiʻekiʻe. Hoʻohui, ʻoi aku ka maʻalahi o ka hoʻopili ʻana i ke kaiapuni a makemake paha i ka calibration pinepine a mālama ʻia paha e hōʻoia i ka pololei.
