Inemomita Ā-orooro

He kaupapa rongonui ngā teihana huarere mō te whakamātautau i ngā momo pūoko taiao, ā, ko te tikanga he anemometer kapu māmā me te vane huarere ka whiriwhiria hei whakatau i te tere me te ahunga o te hau. Mō te QingStation a Jianjia Ma, i whakatau ia ki te hanga i tētahi momo pūoko hau rerekē: he anemometer ultrasonic.
Kāore he wāhanga neke o ngā anemometer ultrasonic, engari ko te painga he pikinga nui o te uaua hiko. Ka mahi rātou mā te ine i te wā e pau ana kia whakaatahia e te pāorooro ultrasonic ki te kaiwhiwhi i te tawhiti e mōhiotia ana. Ka taea te tatau i te ahunga o te hau mā te tango i ngā pānui tere mai i ngā takirua pūoko ultrasonic e rua e poutū ana tetahi ki tetahi me te whakamahi i te ine whārite māmā. Ko te whakahaere tika o te anemometer ultrasonic me āta hoahoa te whakakaha anaro i te pito whiwhi me te tukatuka tohu whānui hei tango i te tohu tika mai i ngā whakaata tuarua, te horapa maha-ara, me ngā haruru katoa i puta mai i te taiao. Kua tuhia pai ngā tukanga hoahoa me ngā tukanga whakamātautau. Nā te mea kāore i taea e [Jianjia] te whakamahi i te kauhanga hau mō te whakamātautau me te whakatikatika, i tāutahia e ia te anemometer ki runga i te tuanui o tana motuka mō te wā poto, ā, ka wehe atu. Ko te uara hua he rite ki te tere GPS o te motuka, engari he paku teitei ake. Tērā pea nā ngā hapa tatau, nā ngā āhuatanga o waho rānei pēnei i te hau, ngā raruraru rere rānei mai i te waka whakamātautau, i ētahi atu waka rori rānei.
Ko ētahi atu pūoko ko ngā pūoko ua whatu, ngā pūoko mārama, ngā pūoko mārama me te BME280 hei ine i te pēhanga hau, te haumākū me te pāmahana. Kei te whakamahere a Jianjia ki te whakamahi i te QingStation ki runga i tētahi poti motuhake, nō reira i tāpirihia e ia he IMU, he kāpehu, he GPS, me te hopuoro mō te oro taiao.
Nā ngā whanaketanga o ngā pūoko, ngā hikohiko, me te hangarau tauira, kua māmā ake te hanga i tētahi teihana huarere whaiaro. Mā te wātea mai o ngā kōwae whatunga utu iti ka taea e tātou te whakarite kia taea e ēnei taputapu IoT te tuku i ā rātou mōhiohio ki ngā pātengi raraunga tūmatanui, me te whakarato i ngā raraunga huarere e tika ana mō ngā hapori o te rohe.
Kei te ngana a Manolis Nikiforakis ki te hanga i tētahi Piramiti Huarere, he taputapu ine huarere āhua totoka katoa, kāore he tiaki, he mana motuhake ki te pūngao me te whakawhitiwhiti kōrero, i hangaia mō te whakatinanatanga tauine nui. I te nuinga o te wā, he pūoko kei ngā teihana huarere e ine ana i te pāmahana, te pēhanga, te haumākū, te tere o te hau me te ua. Ahakoa ka taea te ine i te nuinga o ēnei tawhā mā te whakamahi i ngā pūoko āhua totoka, ko te whakatau i te tere o te hau, te ahunga, me te ua me whakamahi i tētahi momo taputapu hiko.
He uaua, he wero hoki te hoahoa o aua pūoko. I te wā e whakamahere ana i ngā whakatinanatanga nui, me whakarite hoki he iti te utu, he ngāwari te tāuta, ā, kāore e hiahiatia he tiaki auau. Mā te whakakore i ēnei raruraru katoa ka arahi pea ki te hanganga o ngā teihana huarere pono ake, iti ake te utu, ka taea te tāuta i roto i te tini ki ngā wāhi tūmatanui.
He whakaaro ā Manolis mō te whakaoti rapanga. Kei te whakamahere ia ki te hopu i te tere me te ahunga o te hau mai i te ine tere, te gyroscope me te kāpehu i roto i tētahi waeine pūoko inertial (IMU) (tērā pea he MPU-9150). Ko te mahere he whai i te nekehanga o te pūoko IMU i a ia e piu haere ana i runga i te taura, pērā i te pendulum. Kua mahia e ia ētahi tātaitanga ki runga i tētahi tauera, ā, e tino whakapono ana ia ka puta ngā hua e hiahiatia ana e ia i te whakamātautau i te tauira. Ka mahia te pūoko capacitive mā te whakamahi i tētahi pūoko motuhake pērā i te MPR121, i te mahi pā rānei i roto i te ESP32. He mea tino nui te hoahoa me te taunga o ngā ara hiko mō te ine tika i te ua mā te kite i ngā pata ua. He mea nui anō hoki te rahi, te āhua me te tohatoha taumaha o te whare e whakanohoia ana te pūoko nā te mea ka pā ki te whānuitanga, te taumira me te tika o te taputapu. Kei te mahi a Manolis i ētahi whakaaro hoahoa e whakamahere ana ia ki te whakamātau i mua i te whakatau mēnā ka noho te teihana huarere katoa ki roto i te whare hurihuri, ko ngā pūoko anake rānei kei roto.
Nā tōna hiahia ki te matawhenua, i hanga e [Karl] tētahi teihana huarere. Ko te mea hou rawa atu ko te pūoko hau ultrasonic, e whakamahi ana i te wā rere o ngā pāoro ultrasonic hei whakatau i te tere o te hau.
E whakamahi ana te pūoko o Carla i ngā whakawhiti orooro e whā, e anga ana ki te raki, ki te tonga, ki te rawhiti me te hauauru, hei kite i te tere o te hau. Mā te ine i te wā e haere ai te pāorooro orooro i waenga i ngā pūoko i roto i te rūma, me te tango i ngā inenga o te mara, ka whiwhi tātou i te wā rere mō ia tuaka, ā, nō reira ko te tere o te hau.
He whakaaturanga whakamiharo tēnei o ngā otinga hangarau, me tētahi pūrongo hoahoa tino taipitopito.
