Nthawi zina umafunika kudziwa kutentha kwa chinthu chapatali. Itha kukhala nyumba yautsi, yowotcha nyama, ngakhale nyumba ya akalulu. Pulojekitiyi ikhoza kukhala yomwe mukuyang'ana.
Muzilamulira kutali nyama, koma osati macheza. Muli ndi MAX31855 thermocouple amplifier yopangidwira kugwiritsidwa ntchito ndi ma thermocouples otchuka amtundu wa K. Zimagwirizanitsa ndi microcontroller ya Texas Instruments CC1312 yomwe imatumiza miyeso ya kutentha pa protocol ya 802.15.4 yomwe matekinoloje monga Zigbee ndi Thread amachokera. Imatha kutumiza mauthenga a pawailesi pamtunda wautali popanda kugwiritsa ntchito mphamvu zambiri, zomwe zimapangitsa kuti zitheke kugwiritsa ntchito batire la CR2023 coin pa ntchitoyi. Kuphatikizidwa ndi firmware yomwe imapangitsa kuti dongosololi ligone pamene palibe miyeso yomwe ikuyesedwa, ikuyembekeza kuti polojekitiyi idzagwira ntchito kwa zaka zingapo pa batri imodzi.
Mauthenga amasonkhanitsidwa ndikulowetsedwa muzokonda za Grafana, komwe amatha kukonzedwa mosavuta. Kuti muwonjezere phindu, kutentha kulikonse kunja kwa mtundu wokhazikitsidwa kumayambitsa chenjezo la smartphone kudzera pa IFTTT.
Kuyang'anitsitsa kutentha ndi chinsinsi chophikira zakudya zokoma ndi anthu osuta fodya, choncho ntchitoyi iyenera kukhala yabwino. Kwa iwo omwe akufuna kuyang'anira kutentha kwawo kutali ndi zovuta zochepa, izi ziyenera kugwiranso ntchito!
Muzovuta kwambiri, thermocouple yokhayo imatha kugwiritsidwa ntchito kulipiritsa capacitor ndi mphamvu yotumizira ...
Momwe malingaliro anu amapitira, poyambira nditha kuwerenga pepala lofufuzira la 1968 RCA la NASA kuti muwone zomwe ziyenera kugwiritsidwa ntchito mkati mwa RTG* (magetsi omwe amagwiritsidwa ntchito mu 1977 Voyager probe amayenera kuwonekera apa).
Kumbukirani kuti ngati mukufuna kugwiritsa ntchito thermocouple kuyeza china chake, molondola kwambiri ** simukufuna (kapena pang'ono) pakalipano kuyenda.
Komabe, ngati mukufuna kuti mphambano ipange mphamvu, ndiye kuti muyenera kujambula momwe mungathere pamene mukukweza mphamvu zowonjezera kuti zikhale zocheperapo kusiyana ndi voteji (kutsika kwa voteji pamtunda kudzachepetsedwa, ndipo kutsika kudutsa kulumikiza waya, popeza ali ndi kukana, momwe mumakokera panopa, ndipo kukana kumasinthanso ndi kutentha - kumtunda kwamakono, kutentha kwapamwamba).
Ndikudabwa ngati ndizotheka kupanga mita ya 2D yachangu komanso yakuda komwe ndimayesa pano ndi magetsi ndikuyesa kutentha. Kenako tebulo loyang'ana limangogwiritsidwa ntchito poyezera zapano ndi magetsi, osati pamachitidwe amtundu, mawonekedwe osasunthika, komanso muyeso wa kutentha.
Pogwiritsa ntchito tsamba lathu ndi ntchito zathu, mumavomereza mwatsatanetsatane kuyika kwa magwiridwe athu, magwiridwe antchito ndi kutsatsa ma cookies.phunzirani zambiri
