Enye yeenzwa zezona zicelo zininzi, ngakumbi kwicandelo lokhuseleko, kunjalo Inzwa yePIR. Enye inzwa entsha yokujoyina uluhlu lwezinto, kwaye sithetha ngayo xa sijongana nemodeli IHC-SR501, yenye yezivamvo ezibonakalayo onokuzisebenzisa ibhodi yakho ye-arduino ngobuninzi beeprojekthi, ezinje ngokwenza ialam ekhayeni lakho okanye kwishishini.
Inzwa ye-PIR ilula kakhulu malunga nonxibelelwano kunye nenkqubo, kodwa unokuqinisekisa ukuba ikhona ubuninzi bezicelo apho inokusetyenziselwa iiprojekthi zakho ze-DIY. Kwaye kwesi sikhokelo sokwazisa uya kuqonda yonke into ebalulekileyo malunga nolu hlobo lwenzwa ...
Yintoni inzwa ye-PIR kunye nomgaqo osebenzayo
Un Inzwa yePIR Luhlobo lwenzwa esebenzisa i-IR, okt infrared. Ngokusekwe kule radiation, iya kusebenza ngokufumana iintshukumo okanye ukusondela. Yonke imibulelo kwizinto ezidibeneyo zokubamba ubukho babantu okanye ukuhamba, kunye nezilwanyana kunye nezinye izinto.
Konke kusekwe kwi Imitha ye-IR esezantsi Ikhutshwe yimizimba yezinto, yabantu okanye izilwanyana. Kwaye iya kubanjwa ngolu hlobo lwenzwa ngokuchaneka okukhulu. Umgaqo ofanayo osetyenziswa zezinye izixhobo, ezinje ngezixhobo ze-thermography, iikhamera zombono ebusuku, njl.
Ukongeza, olu hlobo lwenzwa lunokuqwalaselwa lungelelanisa ubuntununtunu bayo, ukuze ibenendawo engaphezulu okanye encinci. Umzekelo, ezinye iisenzi zinokuba nentshukumo okanye ubukho bokubona kuluhlu ukusuka kwiimitha ezi-3 ukuya kwi-7 yeemitha okanye nangaphezulu, kwaye zinama-90-110º. Oku kuvumela ukukhangela intshukumo kuluhlu olulungileyo, ukuvumela ukufakwa kwayo kulo naluphi na udonga, umzekelo.
Kwelinye icala, inzwa ye-PIR iya kugutyungelwa likhaka elime okomthi. Ayisiyonto ngaphandle komnxeba Iilensi zeFresnel. Oko kukuthi, ilensi ebizwa ngegama lefiziksi yaseFrance eyayiqulunqayo, uAugustin-Jean Fresnel, kwaye enkosi apho unokufezekisa khona ukugquma okukhulu ngaphandle kwesidingo sezinye iilensi ezinobunzima obukhulu kunye nevolumu eya kufuneka kusetyenziswa ilens eqhelekileyo.
Izicelo
Ukuba uyazibuza ukuba yeyiphi inzwa ye-PIR enokusetyenziselwa yona, inyani kukuba inezinto ezininzi izicelo apho kunokuba yimfuneko ukusebenzisa olu hlobo lwesixhobo. Umzekelo:
- Iirobhothi ezizimeleyo ezifuna ukubona izinto okanye abantu ukuthintela imiqobo.
- Izithuthi ezizimeleyo ezifuna ukubona intshukumo okanye ubukho bento ethile.
- Iinkqubo zeAlarm apho zisebenza khona xa zibhaqa ubukho bento ethile. Iinkqubo zokujonga ividiyo zinokusebenza ukuze zirekhode okwenzekayo xa zibona intshukumo, izivulo zeminyango, iintsimbi zokungena emnyango, njl.
- Iinkqubo ezizenzekelayo ezikhanyisa isibane xa kufunyanwa umntu, okanye zivule iingcango ngokuzenzekelayo.
- Izixhobo ezilumkisa okanye zivelise uhlobo oluthile lomsebenzi xa kusenzeka isiganeko, njengesilwanyana sasekhaya esikufuphi, okanye umntu osondele kwisenzi se-PIR.

Thenga inzwa yePIR
Kuxhomekeke kwinto oyikhangelayo uya kuba nayo iindlela ezininzi kwintengiso. Umzekelo, ukuba ungumenzi kwaye ujonge icandelo elektroniki ukulilungelelanisa neprojekthi ye-elektroniki, ke uneemodeli ezininzi, ezinje:
Kwelinye icala, kunokwenzeka ukuba yeyiphi into onomdla kuyo osebenza ngayo ngenzwa ye-PIR ilungele ukusetyenziswa Kwialam yakho okanye ukukhanyisa izibane ngokuzenzekelayo, njl. Kule meko, eyona nto ilungileyo kukuba usebenzisa inzwa ye-PIR yentengiso enje ngezi:
- SEBSON, Inzwa eshukumayo esekwe kwi-PIR yofakelo lwangaphandle. Ngoluhlu oluya kwiimitha ezili-12 kude, kunye ne-180º angle, ehlengahlengiswayo ekuqhelaniseni, kunye ne-ankile edongeni.
- IPIR LKM, Inzwa ye-PIR yesixhobo esisebenza ngamandla ebhetri yokuyifaka naphi na xa uyifuna, enoluhlu lweemitha ezili-11, i-110º engile ethe tyaba kunye ne-60º ngokuthe nkqo.
- Akukho mveliso ifunyenweyo, Enye yeempawu ezaziwayo kukhuseleko oluqinisekileyo kunye nokubonisa le sensor ingena-PIR engenazingcingo kwaye ilungele ii-alamu. Ukufikelela kwiimitha ezili-100 zoluhlu kunye nokusetyenziswa kwangaphakathi.
- UDiocheInzwa ekhuselweyo ngokuchasene nezinto ezisetyenziselwa ngaphakathi nangaphandle kwekhaya. Kuluhlu olubanzi ukunqanda amabala angaboniyo kunye nokulumkisa nge-mobile app.
- ooziro, Inzwa ye-PIR engu-360º enokufakwa kumngxunya wokukhanya esilingini, ithathe indawo yenye yezona ndawo zibukhali unazo ekhayeni lakho okanye eofisini. Ukongeza, kubonakala ngathi ibhalbhu eqhelekileyo ayizukubonwa.
- I-Tellur Smart, enye onokuyidibanisa ne-WiFi, njengazo naziphi na izixhobo ze-IoT zolawulo olukude kwiselfowuni yakho okanye ukuvelisa amanyathelo kwezinye izixhobo ezixhumeneyo xa ifumana intshukumo, njengokuvula iswitshi, njl.
Njengoko ubona, ezi nkqubo zitshiphu kakhulu, Ke kwii-euro ezimbalwa unokuba nenye okanye nangaphezulu ekhaya ukwenza inkqubo oyifunayo.
Sebenzisa inzwa yePIR ngeArduino
Ukuba ufuna ukusebenzisa Inzwa yePIR ngeArduino, Ndikucebisa ukuba ufunde inqaku malunga IHC-SR501. Apho ndacacisa ukuba ingasetyenziswa njani kwaye idityaniswe neprojekthi kunye neArduino. Kwimeko apho uthenge enye imodeli yesenzi se-PIR, ndincoma ukuba ufunde i-datasheet kunye ne-pinout kwimodeli ethile, kodwa ayifanelanga ukubonisa ubunzima obufanelekileyo, kwaye oko kwathethwayo kweli nqaku kunokuba sisiseko sokuyiqhelanisa isivamvo esitsha ...
