Iprojekthi yesikhululo semozulu inendlela ecacileyo: guqula iisensa ezimbalwa zibe ngamanani, amanani abe yirekhodi egciniweyo, kwaye loo rekhodi ibe yideshbhodi iklasi enokuyifunda ngephanyazo. Umsebenzi wahlulwa ube ngamanqanaba amahlanu, khetha iisensa zakho, uzibeke kwiindawo ezifanelekileyo, urekhode idatha, uyenze igrafu, uze wongeze imithetho embalwa yoqikelelo, kwaye inqanaba ngalinye lifundisa into yalo. Esi sikhokelo sihamba yonke le ndlela ukuze utitshala okanye umfundi onomdla akwazi ukucwangcisa isakhiwo esimelana nemozulu yokwenene.

Qala ngoko ufuna ukukulinganisa

Isilingo kukuthenga ikhithi enkulu yeesensa kuqala uze uzame ukufumana injongo emva koko. Yenza ngendlela echaseneyo. Gqiba ukuba yiyiphi imibuzo ekufuneka isikhululo siyiphendule, ihardware ilandele emva koko. Ubushushu nomswakamo sisibini sokuqala esifanelekileyo: kutshiphu ukukufunda, kulula ukukwenza igrafu, kwaye kunentsingiselo ngokukhawuleza. Uxinzelelo lomoya liqhawe elithuleyo, alwenzi lukhulu lwedwa kodwa luvula uqikelelo olusisiseko xa ulandelela indlela olutshintsha ngayo. Imvula nomoya kubuyisela okuhle kodwa kunemichini, ngoko kuphathe njengenqanaba lesibini xa icala le-elektroniki selizinzile.

Kwisakhiwo sokuqala segumbi lokufundela, jonga kumalinganiselo amathathu onokuwathemba endaweni yesixhenxe oziqonda kancinci. Isikhululo esirekhoda ubushushu, umswakamo noxinzelelo ngokuthembekileyo inyanga epheleleyo yiprojekthi engcono kunesiso esifunda yonke into usuku olunye size sikhukhuliseke.

Ukukhetha iisensa zakho

Uninzi lwezikhululo zesikolo luxhomekeke kwiseti encinci yezinto ezibhalwe kakuhle. Awufuni zixhobo zelebhu; ufuna iisensa umlawuli wakho anokuzifunda nezinokuxhunywa ngabafundi bakho ngaphandle kweenyembezi.

• Ubushushu nomswakamo — isensa yedijithali edibeneyo (iimodyuli eziqhelekileyo zohlobo lwe-DHT) inika zombini ngesixhobo esinye nangepini enye yedatha.
• Uxinzelelo lomoya — isensa ye-barometric (yohlobo lwe-BMP) yongeza uxinzelelo kwaye idla ngokongeza nesifundo sesibini sobushushu sokujonganisa.
• Ukukhanya — i-resistor exhomekeke kukukhanya yindlela etshiphu yokurekhoda ubude bemini nokugquma kwamafu, kwaye sisingeniso esithambileyo kumanani e-analogue.
• Imvula — isikali sebhakethi ethululayo sibala amaphuphuma; ukuthulula ngakunye ngumthamo omiselweyo, ngoko isoftwe yenza izibalo.
• Umoya — i-anemometer yesantya nesalathisi somoya secala esivela kuso zezona zinto zisebenza ngomatshini yaye zezona zisilela lula phandle.

Umlawuli ophakathi ubaluleke njengeesensa. Ibhodi eneepini ezinamagama acacileyo, okungenayo kwe-analogue nokwedijithali, kunye nendawo yokuprograma exolelayo yonga iiyure. Ibhodi ye-sheenbot∞ esiyisebenzisayo eklasini igubungela iintlobo eziqhelekileyo zeesensa kwaye ivumela abafundi ukuba basuke kwisifundo esinye baye kumjikelo wokurekhoda onexesha ngaphandle kokutshintsha izixhobo. Nokuba ukhetha ntoni, thenga isensa enye okanye ezimbini zongezelelo kwasekuqaleni; i-odolo oyenzayo namhlanje kwivenkile itshiphu kunesifundo osilahlekelwa siso ngenxa yesixhobo esifileyo kwinyanga ezayo.

Indawo yokubeka: icandelo abalitsibayo abafundi

Isensa elungileyo endaweni engalunganga inika amanani azithembileyo, kodwa angachanekanga. Indawo oyibeka kuyo kulapho iprojekthi yemozulu iba yinzululwazi yokwenene khona. Impazamo eqhelekileyo yisensa yobushushu exhonywe eludongeni lwezitena olutshiswa lilanga, elinganisa udonga, kungekhona umoya.

• Beka iisensa zobushushu nezomswakamo emthunzini, umoya uhamba ngokukhululekileyo ujikeleze zona. Ibhokisi enemicikilishane evulekileyo, isikrini se-Stevenson esenziwe ekhaya, sisisombululo esidala.
• Zixhome malunga nobude besifuba, kude netarha, kwikhonkrithi nakwiimpumlo zoomatshini bomoya ezikhupha ubushushu obugcinweyo.
• Gcina isikali semvula endaweni evulekileyo, kude kwiimpahla zophahla nakwimithi ejingayo, umphetho waso ulinganile.
• Beka iisensa zomoya phezulu nasendaweni evulekileyo kangangoko unokwenza ngokukhuselekileyo; izakhiwo zenza izijikelezi ezenza amanani angabi nantsingiselo.
• Cwangcisa amandla ombane. Njengoko ukucinywa kombane kuyinyani ebomini besikolo, isikhululo esisebenza ngebhetri encinci okanye esirekhoda kwindawo yokugcina esekhaya siya kuhlala ixesha elide kunesiso esifa qho xa umbane ucinywa.

Ukurekhoda nokwakha ideshbhodi

Ukurekhoda kukufunda nje iisensa ngexesha elimisiweyo uze ubhale phantsi isifundo ngasinye kunye nexesha laso. Rhoqo emva kwemizuzu elishumi elinesihlanu okanye engamashumi amathathu kwanele kwimozulu, etshintsha kancinci. Zimbini iindlela ezinyanisekileyo zokugcina: bhala kwikhadi le-SD okanye kwimemori esebhodini uze uyilande kamva, okanye thumela isifundo ngasinye nge-WiFi kwispredishithi okanye kwiphepha elincinci lewebhu. Ukugcina esixhotyweni kuqinile ngakumbi kwaye kufundisa ukusingatha iifayile; ukuthumela ngothungelwano kuyachulumancisa ngakumbi kwaye kufundisa indlela idatha ehamba ngayo. Iiklasi ezininzi zenza eyokuqala, zize ziphakamele kweyesibini.

Ideshbhodi kulapho amanani aba yingqiqo khona. Ikholam yamanani ayikuxeleli nto; loo datha inye njengegrafu yomgca ngokuhamba kwexesha ikuxelela ukuba imini yaphola phambi kwemvula yaza yafudumala emva kwayo. Qalisa kwispredishithi, abafundi bancamathisele irekhodi, benze itshati yobushushu ngokwexesha, babone ipatheni ngoko nangoko. Iqela elinamabhongo ngakumbi lingakha iphepha lewebhu elilula elifunda ukuthunyelwa okuphilayo lize lizoba ezo grafu zinye ngokuzenzekelayo. Gcina ideshbhodi yokuqala idikayo kwaye ifundeka: iilebheli ze-axis ezicacileyo, iiyunithi ezinengqiqo, umgca omnye kumlinganiselo ngamnye.

Imithetho elula yoqikelelo

Uqikelelo lubonakala ngathi lelona candelo linzima; inguqulelo yasegumbini lokufundela yimithetho embalwa esekelwe kwirekhodi yakho yoxinzelelo. Owona mqondiso uluncedo ngumkhwa, kungekhona ixabiso: uxinzelelo olwehla ngokuzinzileyo kwiiyure ezimbalwa ludla ngokuthetha ukuba kuza imozulu engazinzanga okanye enemvula, ngelixa ukunyuka okuzinzileyo kukhomba ekucacisweni nasekuzoleni. Dibanisa oko nomswakamo onyukayo ngokuya kusiya ngokuhlwa uze ukwazi ukwenza isiqikelelo esiyinyani sentsasa elandelayo.

Bhala imithetho njengezivakalisi ezilula zokuba-ke eziyilwe ngabafundi ngokwabo. Ukuba uxinzelelo lwehle ngaphezu komlinganiselo omisiweyo ukususela kusasa, phawula ukuba imvula inokuna. Baya kuphosisa ngamanye amaxesha, yiloo nto kanye eyinjongo: ukuthelekisa uqikelelo lwayizolo nesibhakabhaka sanamhlanje sisifundo sonke. Njengoko iKapa iphuma ebusika bayo obumanzi ingena entwasahlobo, irekhodi yoxinzelelo inika iklasi into eqinileyo enokuxoxwa ngayo.

Ulwandiso nesishwankathelo

Xa umjikelo osisiseko sele uqinile, ulwandiso olumnandi lutshiphu. Yongeza isilumkiso: ibhuzari okanye i-LED evulekayo xa kugqithwa umgangatho womkhenkce, okanye umqondiso xa imvula ifunyanwa okokuqala. Thelekisa isikhululo sakho nerekhodi esemthethweni evela kwi-South African Weather Service ngosuku olunye, nize nixoxe ngokuba kutheni uphahla lwesikolo nomgca wokuhlalisa iinqwelomoya zingavumelani. Faka amanani kukhuphiswano lweklasi, okanye unikezele isikhululo esigqityiweyo kwiqela lonyaka ozayo njengeseti yedatha eqhubekayo.

Yakha into encinci, ukhethe indawo ngocoselelo, urekhode ngokunyaniseka, uze uvumele igrafu ifundise. Isikhululo semozulu yenye yeeprojekthi ezimbalwa eziqhubeka zinika idatha emva kokuba amanqaku engenisiwe. Ukuba ungathanda ukuba abafundi bakhe esinye ngokukhokelwa, iiwekshopu zeeholide zethu neeklasi zeveki nganye ziqhuba iiprojekthi ezikwimo enje kanye, kwaye ungakhangela ezinye izibhalo zokwakha kwigumbi leendaba.

Imibuzo ebuzwa rhoqo

Yeyiphi eyona khithi isisiseko yesikhululo semozulu sokuqala?

Ibhodi ye-microcontroller, isensa edibeneyo yobushushu-nomswakamo, indlela yokugcina okanye yokuthumela amanani, nendlela yokuwenza igrafu. Yonke enye into, uxinzelelo, imvula nomoya, luphuculo olongezayo xa loo mjikelo usisiseko sele usebenza wodwa iveki yonke.

Isikhululo simele sithathe isifundo kangaphi?

Rhoqo emva kwemizuzu elishumi elinesihlanu ukuya kwengamashumi amathathu kuyayifanela imozulu, etshintsha kancinci, kwaye kugcina irekhodi incinci ngokwaneleyo ukuze yenziwe igrafu lula. Ukuba ulandela isiganeko esikhawulezayo esinjengesaqhwithi esidlulayo, yehlisela kwisifundo umzuzu ngamnye ngelo thuba, uze ubuyele kumrhubhe ocothayo.
