Txais tos rau kuv 'ntsuab' qhia! Kuv yuav qhia koj li cas siv Arduino, ob lub cav servo lub ntsuas kub thiab qee cov hlau (lossis ntoo) los ua lub ntsuas cua sov digital rau chav tsev HVAC. Raws li CB Richard Ellis (lub tuam txhab kev lag luam loj), New York City yog lub khw muag khoom, nrog tsuas yog kwv yees li 1/3 ntawm cov pej xeem muaj lawv lub tsev (piv rau yuav luag 70% cov tswv tsev nyob rau lwm lub tebchaws Asmeskas). Qhov no txhais tau tias ntau dua 5 hli tib neeg hauv NYC nyob hauv tsev xaum lossis tsev. Nws yog qhov tsawg heev rau chav xauj kom muaj ib qho ntawm lub hauv paus cua txias lossis txawm tias muaj qhov ntsuas cua sov. Ntau chav tsev muaj chav nyob ruaj khov dhau ntawm phab ntsa zoo li qhov pom hauv video hauv qab no. Hmoov tsis zoo, cov chav no tsis muaj peev xwm tswj hwm qhov kub thiab tsuas tuaj yeem raug yuam kom sov, txias, lossis tawm. Raws li Lub Chaw Siv Hluav Taws Xob, Cov Cua Kub thiab Cua Txias suav txog li 45 feem pua ntawm koj daim nqi zog. Tsoomfwv tseem fwv kwv yees tias tus tswv tsev nruab nrab siv ntau dua $ 10, 000 rau cua sov thiab cua txias hauv kaum xyoo. Lub peev xwm txias ntawm chav cua txias tau ntsuas hauv BTUs, lossis Cov Khoom Siv Hluav Taws Xob Hauv Tebchaws Askiv, ib teev twg. Kom txias 700-1, 000 sq ft chav tsev (ib chav pw lossis tej zaum muaj 2 chav me me), koj xav tau txog 20, 000 BTU's. Qhov no yog qhov sib npaug ntawm 1.7 tons lossis 5, 861 watts. Ntawm $ 0.15 ib kWh, qhov ntawd txhais tau tias nws raug nqi $ 0.88/teev los khiav koj chav HVAC! lub hnub qub zog (piv txwv tias muaj txiaj ntsig ntau dua) lossis tswj hwm lawv lub cev kub, Kuv xav nrhiav txoj hauv kev, yam tsis hloov pauv mus tas li, los tswj hwm chav HVAC zoo li lub ntsuas cua sov! Kev siv cov cuab yeej no tuaj yeem tsis tsuas yog txuag koj cov nyiaj, tab sis tuaj yeem pab tswj qhov kub thiab txias nyob hauv koj chav tsev, txo kev siv hluav taws xob thiab pab txo qhov teeb meem tso rau hauv peb lub teb chaws lub zog hluav taws xob thaum lub caij sov lub hli!

Kauj Ruam 1: Txheej txheem cej luam ntawm Cov Khoom & Cov Npe

Txheej txheem cej luam & Cov npe ntu: Cov Khoom Siv Hluav Taws Xob: 1) Ob Qhov Kev Pabcuam. Kuv siv Hitec HS-311 (https://www.hitecrcd.com/servos/show?name=HS-311) uas tuaj yeem yuav qis dua $ 10 toj ib servo. SparkFun servo (https://www.sparkfun.com/commerce/product_info.php?products_id=9064) yuav tsum ua haujlwm. 2) Kev Ntsuas Kub: https://www.sparkfun.com/commerce/product_info.php?products_id = 2453) Arduino (Kuv siv Duemilanove - https://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=50)4) Kuv siv Adafruit ProtoShield (https://www.adafruit.com/ index.php? main_page = product_info & cPath = 17_21 & products_id = 51) tab sis koj tseem tuaj yeem siv daim ntawv me me (https://www.sparkfun.com/commerce/product_info.php?products_id=8802)5) 4K7 resistor rau Kub Sojntsuam: https://www.radioshack.com/product/index.jsp?productId=20623466) 9V Wall adapter: https://www.adafruit.com/index.php?main_page=product_info&cPath=17_22&products_id=63Hardware Parts List: 1) Kuv siv Aluminium yuav los ntawm kuv lub khw kho vajtse hauv zos (Tsev Depot). Qhov ntev ntawm servo bracket yog 4 "x 1" x 0.25 "thiab ob qhov kawg-tshaj tawm yog 1" x 0.25 "x 0.25". Xwb, ntawm no yog qhov txuas los yuav qhov khoom me me ntawm txhuas hauv online: https://www.speedymetals.com/pc-2241-8351-14-x-1-6061-t6511-aluminium-extruded.aspx thiab http:/ /www.speedymetals.com/pc-2494-8378-12-sq-6061-t6511-aluminium-extruded.aspx2) Kuv siv (6) 1/2 "8-32 SHCP (lub taub hau taub hau ntswj ntsia hlau) thiab (2) 1 "8-32 SHCP tus. Kuv yuav pom zoo yuav cov no los ntawm koj lub khw muag khoom kho vajtse hauv ib cheeb tsam, tab sis lawv kuj tuaj yeem yooj yim yuav online. Nov yog qhov txuas: 1/2 ": https://www.use-enco.com/CGI/INSRIT?PMAKA=430-0041 thiab 1": https://www.use-enco.com/CGI/INSRIT PMAKA = 430-0045.3) Koj yuav xav tau tus kais uas phim cov ntsia hlau twg koj siv hauv qib dhau los. Txij li thaum kuv siv 8-32 screws, Kuv yuav 8-32 kais. Ib zaug ntxiv, qhov no tuaj yeem yuav ntawm koj lub khw muag khoom kho vajtse hauv ib cheeb tsam tab sis yog tias koj xav xaj online, ntawm no yog qhov txuas: https://www.use-enco.com/CGI/INSRIT?PMAKA=325-47724) Tus lej 29 laum me ntsis (qhov no sib xws rau 8-32 cov kais dej; yog tias koj siv qhov sib txawv me me ntsia hlau & coj mus rhaub, yuav qhov tsim nyog laum me ntsis). NCO TSEG: Ntau lub khw muag khoom kho vajtse muag cov kais dej nrog cov khoom siv laum, uas yuav ua kom koj yuav qhov loj me. Kuj muaj nyob ntawm no: https://www.use-enco.com/CGI/INSRIT?PMAKA=325-6119Tools:1) Kuv siv lub laum (tuaj yeem yog siv tes siv lossis laum xovxwm) thiab hacksaw. 2) Yog tias koj xav theej cov servo mus rau aluminium mount (piv rau qhov drilling thiab siv lub qhov), Kuv xav kom siv JBWeld lossis Gorilla Glue Arduino Library: Ntxiv rau lub tsev qiv ntawv servo (suav nrog Arduino softwre), koj xav tau OneWire lub tsev qiv ntawv. Koj tuaj yeem nyeem ntxiv txog lub tsev qiv ntawv ntawm no (yeem): https://www.arduino.cc/playground/Learning/OneWire lossis tsuas yog rub lub tsev qiv ntawv los ntawm qhov txuas no: https://homepage.mac. com/wtpollard/Software/FileSharing7.html

Kauj Ruam 2: Txhim Kho Servo Mount & Hluav Taws Xob Schematic

Nov yog cov vis dis aus hais txog yuav tsim li cas servo mount thiab cov lej ntawm cov khoom siv hluav taws xob. Txheeb tawm daim duab hauv qab no kom paub ntau ntxiv!

Kauj Ruam 3: Arduino Code

Cov ntaub ntawv txt hauv qab no muaj tus lej Arduino. Koj tuaj yeem qhib cov ntawv no los saib cov cai thiab tom qab ntawd luam/muab nws tso rau hauv koj li software Arduino los ua haujlwm.

Kauj ruam 4: Debugging thiab Txhim Kho

NCO TSEG: Yog tias koj so koj cov arduino ntawm cov hlau, kom paub tseeb tias koj muaj qee cov roj hmab taw rau hauv qab! Txwv tsis pub cov pob qij txha txuas rau hauv qab ntawm Arduino yuav kov cov hlau uas yuav ua rau lub rooj luv luv!

Kauj Ruam 5: Kev Xav Kawg & Lub Tswv Yim Yav Tom Ntej

Kev Xav Thaum Kawg: Tsaug rau saib! Yog tias koj tab tom nrhiav txoj hauv kev zoo kom txuag hluav taws xob, txuag nyiaj thiab tseem muaj chav nyob yooj yim, vam tias koj tau nyiam cov vis dis aus no. Thaum lub hli sov lub caij sov, qhov xav tau siab tshaj yuav tsum tau tsim cov tshuab fais fab ntxiv rau hauv online, uas feem ntau kim dua cov nroj tsuag kom khiav thiab ua rau muaj kuab paug ntau ntxiv rau peb ib puag ncig. Yog tias koj muaj peev xwm hloov kho koj li HVAC system rau lub hnub qub raws li lub zog lossis koj tuaj yeem teeb tsa "tus kws tshaj lij" ntsuas cua sov, thov ua! Tab sis yog tias koj nyob hauv chav tsev thiab yooj yim tsis muaj cov kev xaiv no, thov xav txog txoj haujlwm no rau ib puag ncig! Nov tsuas yog qee qhov: 1) Muab Cov ntsuas Kub Kub rau ntawm xaim xaim kom nws tuaj yeem tso tawm tswv yim hauv chav 2) Ntxiv cov nyees khawm rau Arduino txhawm rau kom muaj plaub hom: Tawm, A/C, Tshav Kub, lossis Kub Ntsuas Hom (piv txwv li tso cai rau koj kom tshem tawm chav nyob, ua kom sov lossis A/C lossis tso cai rau chav ua haujlwm raws li qhov ntsuas kub ntsuas) 3) Siv 7-ntu LED lossis LCD los tso saib qhov ntsuas kub tam sim no 4) Siv Ethernet Shield kom pab tswj Internet lossis tshaj tawm koj qhov ntsuas kub tam sim no (piv txwv li hauv twitter). Lub tswv yim no yog kev tshoov siab los ntawm Adafruit's "Tweet-a-Watt" (https://www.adafruit.com/index.php?main_page=index&cPath=32)5) Siv tus thib peb servo los tswj lub zog kub/txias txias (nco ntsoov: siv peb servo's ntawm arduino xav kom siv softwareservo's - saib ntawm no kom ntau ntxiv: https://www.arduino.cc/playground/ComponentLib/Servo)6) Wireless ntsuas kub ntawm Xbee lossis RF (rau RF, saib https://www.sparkfun.com/commerce/product_info.php?products_id=8946 thiab https://www.sparkfun.com/commerce/product_info.php?products_id=8949)7) Teem qhov ntsuas kub ntawm qhov chaw ntawm lub cuab yeej siv tus keyboard lossis lub zog ntsuas 8) Teeb lub tsev kom txias lub tsev nyob rau qee lub sijhawm (piv txwv li ua ntej koj tuaj txog tom tsev tom haujlwm) lossis mus rau hauv "mem tes" hom hmo ntuj, hloov ntawm qhov txias & txias kom lub tsev txias tab sis tsis muaj AC txhua hmo 9) Siv Evil Mad Scientist lossis ITP Boarduino kom pheej yig dua & chav me dua! Saib https://evilmadscience.com/tinykitlist/74-atmegaxx8 rau Evil Mad Scientist Cov laug cam uas koj tuaj yeem yuav tau ua cov khoom siv uas suav nrog PCB & ATMEL nti thiab 16Mhz siv lead ua & lub kaus mom rau ~ $ 12Tau Nyeem NYU ITP qhia yuav ua li cas thiaj tsim tau ib lub breadboard arduino!
