2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27
Muaj zillion RF chaw taws teeb tswj chaw taws teeb muaj tab sis ib qho ntawm qhov nrov tshaj plaws zoo li yog los ntawm Etekcity. Kuv muaj peev xwm tuaj tos tau, ntawm tus nqi ib txwm, ib txheej ntawm tsib thiab ob lub chaw taws teeb tswj rau tsawg dua $ 30 ntawm Amazon. Kuv tsis paub meej tias kuv yuav ua dab tsi nrog lawv tab sis kuv xav tias nws yog lub sijhawm tseem ceeb los ua qee qhov nyiag nkas. Ib yam uas yuav tsum nco ntsoov yog tias cov no tsuas yog tswj tau nrog cov chaw nyob deb, thiab tsis dhau ntawm is taws nem. Tab sis peb yuav kho qhov ntawd. Tsis tas li, lawv ib txwm tawm thaum ntsaws thiab rov qab mus rau lub xeev ntawd yog tias lub zog poob. Kuv tsis paub txog koj, tab sis kuv muaj qee daim ntawv thov uas kuv xav kom lub qhov hluav taws xob zoo li qub. Peb yuav kho qhov ntawd ib yam. Tsuas yog nco ntsoov tias cov hacks xav tau qee qhov kev paub ntawm cov khoom siv hluav taws xob thiab cov txuj ci yooj yim soldering.
Kauj Ruam 1: Ua Kom Zoo Li Qub
Hloov ib qho ntawm cov qhov hluav taws xob los ntawm ib txwm tawm mus rau ib puag ncig yuav zoo li yog txoj haujlwm yooj yim vim tias lawv siv tus qauv zoo nkauj uas yuav tsum muaj tus pin rau ob lub xeev. Raws li nws hloov tawm qhov txuas mus lossis yuav tsis muaj qhov ib txwm nyob ntawm tus pin, tab sis nws tsis tuaj yeem nkag tau ntawm lub rooj tsav xwm hauv Circuit Court. Qhov ntawd nyuaj rau peb txoj haujlwm tab sis nws tej zaum yog kev nyab xeeb ntse txav los ntawm cov chaw tsim khoom. Qhov ntawd txhais tau li cas, yog tias peb yuav tsum nrhiav txoj hauv kev thim rov qab rau/tawm cov laj thawj.
Muaj ob daim los thim qhov logic. Thawj yog hloov pauv qhov polarity ntawm LED. Cov kab laug sab laug rau LED tau qhia hauv thawj daim duab. Thaum lub LED raug tshem tawm, peb yuav tsum tau txiav ob qho rau hauv cov kab hluav taws xob raws li pom hauv daim duab thib ob. Sab tes xis txiav cais cov kab laug sab LED ntawm hauv av. Peb ua qhov ntawd kom tom qab LED tau thim rov qab, peb tuaj yeem muab cov ntaub qhwv pov tseg rau +5 volts. Sab tes txiav txiav cais lub hauv paus ntawm kev xa cov tsav tsheb transistor los ntawm 4700 ohm resistor. Qhov ntawd yuav tso cai rau ob lub logic polarity thim rov qab los teeb tsa. Txheeb ob zaug nrog lub ntsuas hluav taws xob kom paub tseeb tias kev txiav tau ua tiav. Hauv daim duab thib peb peb tau rov txhim kho lub LED nrog lub anode tam sim no txuas nrog lub ncoo txiav thiab mus rau +5 volts. Cov coj tsuas yog ntev txaus ntawm kuv chav nyob kom kuv tuaj yeem khoov nws mus rau +5 qhov hluav taws xob tso tawm ntawm 78L05 tus tswj hluav taws xob.
Daim duab thib plaub qhia txog txoj hauv kev uas siv los thim rov qab cov laj thawj rau kev tsav tsheb. Kuv siv ib txwm 2N3904 NPN transistor (qhov sib npaug yuav zoo) ua qhov hloov pauv. Lub tshuab tso tawm tau muab pov rau hauv av, lub hauv paus tau txuas mus rau ntawm lub rooj tsav xwm 4700 ohm resistor, thiab tus neeg sau khoom tau muab muag rau lub hauv paus ntawm kev xa tawm tus neeg tsav tsheb transistor. Txhawm rau kom ntseeg tau tias tus xa xov transistor tau hloov pauv ib txwm, Kuv yuav tsum ntxiv 4700 ohm resistor los ntawm nws lub hauv paus rau +5 volts. Tam sim no, thaum cov logic tso tawm siab, nws yuav tig rau lub transistor tshiab uas yuav tua lub transistor tsav tsheb relay.
Kauj ruam 2: Re-xaim Cov Chaw Taws Teeb
Yog tias koj xav nqis tes ua ntxiv koj tuaj yeem hla txoj hlua khawm uas tsim nyog nyob rau hauv cov chaw taws teeb kom lub khawm sab laug yuav tig rau qhov hloov pauv qhov hluav taws xob thiab khawm sab xis tig nws tawm. Yeej koj yuav tsum tau txiav cov kab hluav taws xob uas mus rau qhov hloov pauv kev sib cuag uas ze tshaj plaws rau nruab nrab ntawm lub rooj tsavxwm thiab tom qab ntawd ntxiv cov xov hlau jumper raws li qhia hauv daim duab.
Kauj Ruam 3: Tswj Internet
Muaj ob txoj hauv kev uas tuaj yeem tswj hwm RF tawm ntawm Is Taws Nem. Ob leeg xav tau kev siv tus qauv pheej yig zoo li ESP8266. Ib txoj hauv kev yuav yog xaim mus rau ib qho ntawm cov chaw taws teeb tswj thiab siv lub microcontroller simulate lub pob nyem. Lwm txoj hauv kev tsis yooj yim dua yog siv lub microcontroller los hloov chaw tswj chaw taws teeb. Nov yog qhov uas tau piav qhia ntawm no. Tus tswj hwm lub microcontroller yuav tau txais lus txib ntawm ESP8266, txhais lawv rau hauv tus qauv RF me ntsis kom raug, thiab tom qab ntawd xa tus qauv me ntsis mus rau RF tus xa xov. Nws suab nyuaj tab sis tsuas yog ib feem nyuaj yog xam tawm seb cov cai tswj kom raug yog rau koj li cas ntawm RF qhov hluav taws xob. Muaj ntau qhov tshaj tawm online uas siv tus txais RF thiab lub suab tso rau hauv PC txhawm rau txheeb xyuas cov lej. Kuv muaj cov khoom kim heev uas muaj lub ntsej muag oscilloscope zoo li nws yooj yim rau kuv kom ntes lawv. Kuv kuj tseem muaj RF sniffer Circuit (ntxaws ntxaws ntawm ib qho ntawm kuv lwm cov phiaj xwm hluav taws xob ntawm kuv lub vev xaib) uas tso cai rau kuv mus ntes RF kev xa xov siv lub davhlau ya nyob twg ntawm kuv lub PC.
Zaus rau kev sib txuas lus nrog RF qhov hluav taws xob yog 433.92-MHz thiab cov lus txib suav nrog kev sib txuas ntev, 24 cov ntaub ntawv me me, thiab 1 nres me ntsis. Cov ntaub ntawv siv tus txheej txheem siv yog On-Off-Keying (OOK) uas txhais tau tias cov ntaub ntawv cov khoom sib txawv los ntawm lub sijhawm qhib/tawm. Tsis muaj qhov yuav tsum tau ua hauv OOK rau tus lej ntawm cov khoom lossis lub sijhawm ntev. Tias yog vim li cas thiaj muaj ntau qhov kev hloov pauv tawm rau cov cuab yeej sib txawv. Kuv tau pom thawj txhais tes los ntawm kev txiav txim siab qhov ntsuas kev nyab xeeb thiab huab cua ntsuas. Cov nthwv dej zoo ib yam li qhov tau qhia hauv daim duab ntawm no.
Kauj ruam 4: Kho vajtse
Cov txheej txheem qhia ntawm no yuav luag zoo ib yam rau qhov kuv tau siv hauv ib qho ntawm kuv li kev ua haujlwm Wi-nkaus ua ntej tau teev tseg hauv kuv lub vev xaib. Qhov sib txawv tseem ceeb yog qhov kawg version tsis muaj USB interface tab sis muaj qhov cuam tshuam rau RF transmitter module. Tus qauv xa xov uas kuv siv tau sau tias FS1000A thiab xa tawm ntawm 433.92-MHz. Kuv tsis tau sim lwm tus qauv ntawm RF hloov pauv tab sis feem ntau yuav tsum ua haujlwm tsuav yog lawv muaj cov yam ntxwv zoo sib xws. RF module tau khiav los ntawm +5 volt input thiab nkag tau yooj yim rau 3.3-volt logic qib rau cov ntaub ntawv xov xwm me ntsis ntws los ntawm PIC. Some ESP8266 modules muaj lawv tus kheej 3.3 volt tus tswj hwm nyob rau hauv thiaj li nkag mus rau nws yuav yog 5 volts. Kuv tau suav nrog 3.3 volt tus tswj hwm hauv kuv cov phiaj xwm rau PIC thiab nws tseem tuaj yeem siv rau ESP module yog tias nws tsis muaj nws tus kheej tswj qhov hluav taws xob. Qhov no tso cai rau PIC thiab ESP sib txuas lus ntawm tib qib kev xav uas tsis tas yuav hloov pauv.
Koj tuaj yeem ua kom yooj yim rau ESP kho vajtse los ntawm kev siv ESP-01 tus qauv thiab lub adapter (pom ntawm no). Tus adapter siv +5 volts thiab muaj onboard 3.3 volt tus tswj hwm. Yog tias koj mus rau txoj kev no kuv kuj pom zoo kom koj yuav lub USB interface uas tau tsim tshwj xeeb rau ESP-01. Nws yuav ua kom teeb tsa ESP-01 yooj yim dua.
Kauj ruam 5: Software
Cov npe software muaj nyob hauv qab no. Nws yog qhov txuas ntxiv ntawm cov software kuv tau sau rau yav dhau los Wi-nkaus project. Kuv xaiv qhov ntawd vim tias kuv xav kom muaj qhov xwm txheej teb los ntawm PIC tso tawm ua cov duab yooj yim hloov ntawm cov ntawv. Kuv kuj tau ntxiv cov cai kom tso tawm ib tus lej-tus lej me ntsis kwj mus rau RF transmitter. Ib yam li cov ntawv ua ntej, Kuv siv HTML cov lus txib kom kos cov voj uas sawv cev rau xwm txheej ntawm txhua ntawm tsib lub chaw taws teeb nyob deb. Liab = tawm, ntsuab = rau, thiab dawb = tsis paub. Cov kab nrog "https://yourname.duckdns.org:xxxxx" yuav tsum sawv cev rau koj qhov kev sib txuas DNS, nrog "xxxxx" tus lej chaw nres nkoj tau xaiv rau koj li Wi-nkaus adapter. Qhov tseem ceeb kom nco ntsoov yog tias tsis muaj kev tawm tswv yim los ntawm cov chaw taws teeb hloov lawv tus kheej yog li software tsuas tuaj yeem tswj hwm cov xwm txheej ntawm qhov lus txib zaum kawg xa rau txhua qhov hloov pauv. Qhov ntawd txhais tau tias txhua lub sijhawm muaj lub zog ntawm cov cuab yeej tswj hwm qhov hloov pauv xwm txheej tsis paub txhua. Nov yog nws rau kab ntawv no. Txheeb xyuas kuv lwm cov phiaj xwm hluav taws xob ntawm www.boomerrules.wordpress.com
