Ngamanye amaxesha kufuneka wazi ubushushu bento ukude. Isenokuba yindlu yokutshaya, i-braai, okanye nendlu yoonogwaja. Le projekthi isenokuba yiloo nto uyifunayo.
Lawula inyama kude, kodwa ungathethi kakhulu. Iqulathe i-amplifier ye-thermocouple ye-MAX31855 eyenzelwe ukusetyenziswa ne-thermocouples zohlobo lwe-K ezidumileyo. Iqhagamshela kwi-microcontroller ye-Texas Instruments CC1312 ethumela imilinganiselo yobushushu ngeprotokholi ye-802.15.4 apho kusekelwe khona ubuchwepheshe obufana ne-Zigbee kunye ne-Thread. Iyakwazi ukuthumela imiyalezo yerediyo kumgama omde ngaphandle kokusebenzisa amandla amaninzi, nto leyo eyenza kube nokwenzeka ukusebenzisa ibhetri ye-CR2023 coin cell kule projekthi. Idityaniswe ne-firmware ebeka inkqubo ebuthongweni xa kungekho milinganiselo ithathwayo, ilindele ukuba iprojekthi isebenze ukuya kuthi ga kwiminyaka eliqela kwibhetri enye.
Imiyalezo iqokelelwa ize ingeniswe kwiisetingi zeGrafana, apho zinokudweliswa khona ngokulula. Ukuze ufumane inzuzo eyongezelelekileyo, naliphi na iqondo lobushushu elingaphandle koluhlu olubekiweyo liya kubangela isilumkiso sefowuni nge-IFTTT.
Ukuhlala ujonge ubushushu yeyona nto iphambili ekuphekeni ukutya okumnandi nabantu abatshayayo, ngoko ke le projekthi ifanele isebenze kakuhle. Kwabo bafuna ukujonga ubushushu babo bekude ngaphandle kobunzima, oku kufanele kusebenze!
Kwimeko embi kakhulu, i-thermocouple ngokwayo iya kusetyenziselwa ukutshaja i-capacitor kunye nokunika amandla i-transmitter ...
Ngokuphathelele iingcinga zakho, indawo endiqala kuyo kukufunda iphepha lophando lwe-RCA lika-1968 le-NASA ukuze ndibone ukuba yintoni ekufuneka isetyenziswe ngaphakathi kwi-RTG* (umbane owasetyenziswa kwi-Voyager space probe ka-1977 wawufanele ukuba uvele apha).
Khumbula ukuba ukuba ufuna ukusebenzisa i-thermocouple ukulinganisa into ethile, ukuze ufumane ukuchaneka okuphezulu** kungcono ukuba ungasebenzisi umsinga (okanye umsinga omncinci kakhulu).
Nangona kunjalo, ukuba ufuna i-junction ivelise amandla, kufuneka utsale umbane omninzi kangangoko unako ngelixa ulungisa umbane ophezulu ukuba ube ngaphantsi kombane ophezulu (ukuhla kwe-voltage kwi-junction kuya kuncitshiswa ngakumbi, kwaye ukuhla kwentambo yokudibanisa, ekubeni zinokumelana, kokukhona utsala umbane omninzi, kwaye ukumelana nako kuyatshintsha ngokweqondo lobushushu - okukhona umbane uphezulu, kokukhona ubushushu buphezulu).
Ndizibuza ukuba kunokwenzeka na ukwenza imitha ye-2D ekhawulezayo nengcolileyo apho ndilinganisa khona umbane kunye nombane kwaye ndilinganise ubushushu. Emva koko itheyibhile yokukhangela isetyenziselwa kuphela ukulinganisa umbane kunye nombane, kungekhona imo yokuvelisa, imo engashukumiyo, kunye nemo yokulinganisa ubushushu.
Ngokusebenzisa iwebhusayithi kunye neenkonzo zethu, uyavuma ngokucacileyo ukuba iikuki zethu zokusebenza, ukusebenza kunye neentengiso zibekwe. Funda ngakumbi
