Kwesinye isikhathi udinga ukwazi izinga lokushisa lento ekude. Kungaba i-smokehouse, indawo yokosa inyama, noma indlu yonogwaja. Le phrojekthi evela kuyo kungenzeka ibe yilokho okufunayo.
Lawula ukude inyama, kodwa ungaxoxi. Iqukethe iamplifier ye-thermocouple engu-MAX31855 eyenzelwe ukusetshenziswa nama-thermocouples ohlobo lwe-K adumile. Ixhumeka kusilawuli esincane se-Texas Instruments CC1312 esithumela izilinganiso ezishisayo ngephrothokholi engu-802.15.4 lapho ubuchwepheshe obufana ne-Zigbee ne-Thread busekelwe khona. Iyakwazi ukuthumela imilayezo yomsakazo emabangeni amade ngaphandle kokusebenzisa amandla amaningi, okwenza kube nokwenzeka ukusebenzisa ibhethri yeselula ye-CR2023 kule phrojekthi. Ihlanganiswe ne-firmware eyenza isistimu ilale lapho kungekho zilinganiso ezithathwayo, ilindele ukuthi iphrojekthi isebenze iminyaka embalwa ngebhethri elilodwa.
Imilayezo iqoqwa futhi ifakwe kuzilungiselelo ze-Grafana, lapho ingahlelwa kalula khona. Ukuze uthole inzuzo eyengeziwe, noma iliphi izinga lokushisa elingaphandle kwebanga elimisiwe lizovula isexwayiso se-smartphone nge-IFTTT.
Ukuqapha izinga lokushisa kuyisihluthulelo sokupheka ukudla okumnandi nababhemayo, ngakho le phrojekthi kufanele isebenze kahle. Kulabo abafuna ukuqapha bekude izinga lokushisa labo ngobunzima obuncane, nalokhu kufanele kusebenze!
Esimeni esibi kakhulu, i-thermocouple ngokwayo izosetshenziselwa ukushaja i-capacitor futhi inike amandla isidlulisi ...
Ngokufika kwemicabango yenu, isiqalo sami kungaba ukufunda iphepha lokucwaninga le-RCA lango-1968 le-NASA ukuze libone ukuthi yini okufanele isetshenziswe ngaphakathi kwe-RTG* (amandla kagesi asetshenziswe ku-1977 Voyager probe kufanele ngabe uvele lapha).
Khumbula ukuthi uma ufuna ukusebenzisa i-thermocouple ukukala okuthile, ngokunemba okuphezulu** awufuni ukugeleza kwamanje (noma okuncane kakhulu).
Kodwa-ke, uma ufuna ukuthi i-junction ikhiqize amandla, udinga ukudweba amandla amanje amaningi ngangokunokwenzeka ngenkathi wenza amandla aphezulu abe ngaphansi kwe-voltage ephezulu (ukwehla kwe-voltage kuyo yonke indawo kuzoncishiswa, futhi ukwehla ngaphesheya ucingo oluxhumayo, njengoba lunokumelana, lapho udonsa khona manje, futhi ukumelana nakho kushintsha ngokushisa - okuphakeme okwamanje, ukushisa okuphezulu).
Ngiyazibuza ukuthi kungenzeka yini ukudala imitha ye-2D esheshayo nengcolile lapho ngikala khona okwamanje kanye ne-voltage futhi ngikala izinga lokushisa. Khona-ke ithebula lokubheka lisetshenziselwa kuphela ukulinganisa kwamanje kanye ne-voltage, hhayi kwimodi yokudala, imodi emile, nemodi yokulinganisa izinga lokushisa.
