With the continuous development of science and technology, smartwatches, as one of the representatives of smart wearable devices, have been playing an increasingly important role in our daily life. Smartwatches are able to realize a variety of functions, such as step counting, heart rate monitoring, sleep monitoring, etc., through the built-in various sensors and algorithms. Among them, digital barometric pressure sensor is one of the important sensors in smartwatch, which provides information such as barometric pressure and altitude for smartwatch. In this paper, we will analyze the principle and function of digital barometric pressure sensor applied to smartwatch in detail.

Ke kumu o ka mīkini paʻi kikohoʻe barometric
Digital barometric pressure sensor he ʻano ʻike i hoʻohana ʻia e ana i ke kaomi kinoea, e hoʻohuli ana i ke kaomi kinoea waho i hōʻailona uila ma o ka hale liʻiliʻi o loko a hoʻopuka iā ia i ke kaʻina hana o ka smartwatch ma o ke kikowaena kikohoʻe, a penei kāna mau kumu kumu:
(1) Piezoresistive hopena
Aia ka loko o ka mea ʻike maʻamau i nā mea ʻike piezoresistive liʻiliʻi. I ka hana ʻana o ke kaomi kinoea waho ma ka ʻili o ka mea ʻike, e hoʻololi ʻia ka waiwai kūʻē o ka sensor piezoresistive. ʻO kēia hopena piezoresistive ke kumu o ka hiki i ka sensor barometric pressure sensor ke ʻike i ke kaomi kinoea.
(2) Kaapuni alahaka
I mea e hoʻomaikaʻi ai i ka naʻau a me ka pololei o ka mea ʻike, hoʻohana maʻamau nā mea ʻike kaomi barometric digital i kahi kaapuni alahaka. ʻO kahi kaapuni alahaka he ʻupena kūʻē i loaʻa i nā mea ʻike piezoresistive lehulehu. Ma ke ana ʻana i ka ʻokoʻa kūʻē ma waena o nā mea ʻike like ʻole, hiki ke loaʻa pololei ka ʻike kaomi kinoea.
(3) Hoʻololi A/D
ʻO nā hōʻailona uila i hoʻopuka ʻia mai nā mea ʻike he mau hōʻailona analog, pono e hoʻololi ʻia i nā hōʻailona kikohoʻe e kahi mea hoʻololi A/D i hiki ke hoʻoponopono ʻia a nānā ʻia e ka mea hana o ka smartwatch.
(4) Uku Pāhana
Ma muli o ka hopena nui o ka ea e ka wela, pono nō hoʻi nā mea ʻike ea kaomi i ka uku wela e hoʻopau i ka hopena o ka wela ma nā hopena ana.
Nā hana o Digital Barometric Pressure Sensor no ka polokalamu Smartwatch
Hiki ke hoʻomaopopo i nā hana he nui, a e hoʻokomo ʻia kāna mau noi nui ma lalo nei.
(1) Ana kiʻekiʻe a me ka hana altimeter
Ma ka loaʻa ʻana o ka waiwai kaomi barometric o kēia manawa ma o ka mīkini paʻi barometric kikohoʻe a hui pū me ka uku wela, hiki i ka wati akamai ke helu pololei i ke kiʻekiʻe o kēia manawa. Hāʻawi kēia i ka ʻike hoʻokele koʻikoʻi a me ka hoʻonohonoho ʻana no ka poʻe hauʻoli o waho, a me ka ʻikepili kuhikuhi pono no nā haʻuki e like me ka piʻi mauna a me ka piʻi.
(2) Ka wanana au o ke kaomi ea
Hoʻohana ka wati akamai i kahi ʻenekona kaomi barometric kikohoʻe e nānā mau i nā loli i ka kaomi barometric a no laila e wānana i nā ʻano o ka wā. Ma ka nānā ʻana i ka piʻi ʻana a me ka hāʻule ʻana o ke kaomi ea, hiki i ka smartwatch ke hoʻomaopopo i ka hiki ke hoʻololi i ka wā ma mua a kōkua i nā mea hoʻohana e hoʻomākaukau e like me ia.
(3) Moʻolelo mōʻaukala Barometric Pressure Kūloko
Hiki i ka wati akamai ke hoʻopaʻa i ka hoʻololi ʻana o ke ea i kekahi manawa, pēlā e hana ai i ka ʻikepili mōʻaukala kūloko. He kōkua nui kēia i nā mea hoʻohana e hoʻomaopopo i ke ʻano hoʻololi o ke aniau kūloko.
(4)Comfort Assessment
Hiki i ka smartwatch ke hoʻohui i nā ʻikepili e like me ka barometric pressure a me ka mahana e helu ai i kahi hōʻoluʻolu hōʻoluʻolu e hāʻawi ana i kahi loiloi hōʻoluʻolu o ke kaiapuni o ka mea hoʻohana i kēia manawa, e hāʻawi ana i kahi ʻike ola maikaʻi.
(5)Altitude Training
No kekahi poʻe haʻuki o waho a me ka poʻe ʻoliʻoli mauna, hiki i nā wati akamai ke kōkua iā lākou me ka hoʻomaʻamaʻa kiʻekiʻe ma o ka hoʻohana ʻana i nā mea ʻike kaomi barometric digital. Ma ka nānā ʻana i nā loli i ke kiʻekiʻe i ka manawa maoli, hiki i nā mea hoʻohana ke hoʻomalu i ka ikaika o ka hoʻomaʻamaʻa a me ka manawa hoʻihoʻi e hoʻokō i nā hopena hoʻomaʻamaʻa maikaʻi aʻe.
Hōʻuluʻulu
No ka hōʻuluʻulu ʻana i ka noi smartwatch digital barometric pressure sensor e hāʻawi i nā mea hoʻohana i nā hana kūpono, e hana ana i ka wati ʻaʻole he mea hōʻike manawa a me ka mea hoʻomanaʻo hoʻomanaʻo, akā he mea ʻoi aku ka piha a me ka naʻauao. ʻO ka hoʻohana ʻana i ke kumu a me ka hana o ka sensor barometric pressure sensor e lawe mai i kahi manaʻo hoʻomohala ākea no nā wati akamai, a hāʻawi pū i ka ʻoluʻolu a me ka palekana no nā mea hoʻohana.’ ke ola o kēlā me kēia lā a me nā haʻuki waho. I ka wā e hiki mai ana, me ka holomua mau ʻana o ka ʻepekema a me ka ʻenehana, e hoʻomau mau ʻia ka hana o ka sensor barometric pressure sensor, e lawe mai i nā hiʻohiʻona noi hou a me nā ʻike no nā wati akamai.
ʻO ka mea i luna nei e pili ana i ka noiʻi wati akamai digital barometric pressure sensor loina a me ka hana o ka hoʻolauna kūpono no ka manawa e pili ana i kēia, inā makemake ʻoe e ʻike hou aʻe e pili ana i nā sensors, nā noi uila uila uila, a me ke koho ʻana i ka ʻike, hiki iā ʻoe ke hōʻiliʻili i kēia pūnaewele a i ʻole kaomi ma ka ʻōlelo kūkākūkā pūnaewele no ka ʻike kikoʻī, ʻo ia hoʻi, e lawe mai ʻo WF iā ʻoe e pili ana i nā mea ʻike a me nā ʻike pili ʻoihana uila uila.
