2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Tseem nyob ntawm txoj kev mus ua kom tiav "phiaj xwm yuav los tom ntej", "ESP32 NTP Kev Ntsuas Kub Ntsuas Kev Ntsuas Kub Nrog Steinhart-Hart Kev Kho thiab Tswb Kub" yog Kev Qhia paub qhia kuv yuav ua li cas ntxiv NTP ntsuas kub, piezo buzzer thiab software rau kuv lub peev xwm kov Qhia tau " ESP32 Capacitive Touch Input Siv "Metallic Hole Plugs" rau Khawm "los tsim lub ntsuas cua sov ua noj yooj yim tab sis raug nrog lub ntsuas kub tuaj yeem ntsuas tau.

Peb lub khawm kov lub peev xwm tso cai rau teeb tsa lub tswb ntsuas kub. Nias lub pob hauv nruab nrab qhia qhov "Teeb Tsom Kub" zaub, ua rau sab laug thiab sab xis khawm kom txo lossis nce lub tswb ntsuas feem. Nias thiab tso lub khawm sab laug yuav txo lub tswb kub ib qib, thaum nias thiab tuav lub khawm sab laug yuav txuas ntxiv txo lub tswb kub kom txog thaum tso tawm. Ib yam li ntawd, nias thiab tso lub khawm sab xis yuav ua rau lub tswb kub nce ib qib, thaum nias thiab tuav lub khawm kom raug yuav ua rau lub tswb kub nce mus txog thaum tso tawm. Thaum ua tiav kho lub tswb ntsuas kub, tsuas yog kov lub hauv paus khawm dua kom rov qab mus rau qhov ntsuas kub. Txhua lub sijhawm qhov ntsuas kub sib npaug lossis siab dua lub tswb ntsuas kub, lub piezo buzzer yuav nrov.

Thiab raws li tau hais, qhov ntsuas kub NTP tau siv hauv kev tsim nrog rau Steinhart-Hart equations thiab coefficients tsim nyog rau kev ntsuas kub kom raug. Kuv tau suav nrog cov lus piav qhia ntau dhau ntawm Steinhart-Hart equation, Steinhart-Hart coefficients, qhov faib hluav taws xob thiab algebra hauv Kauj Ruam 1 (raws li cov nyiaj tau ntxiv, nws ua rau kuv tsaug zog txhua zaus kuv nyeem nws, yog li koj yuav xav tau hla Kauj Ruam 1 thiab lub taub hau ncaj mus rau Kauj Ruam 2: Sib sau Cov Khoom Siv Hluav Taws Xob, tshwj tsis yog tias koj xav tau pw tsaug zog).

Yog tias koj txiav txim siab tsim lub ntsuas cua sov ua noj no, rau kev hloov kho thiab luam ntawv 3D Kuv tau suav nrog cov ntaub ntawv hauv qab no:

Thiab ib daim ntawv kawg, Kuv tsis tau txais nyiaj them rau txhua daim ntawv, suav nrog tab sis tsis txwv rau kev kuaj dawb, rau ib qho ntawm cov khoom siv hauv qhov tsim no

Kauj Ruam 1: Lej, Lej thiab Lej Ntxiv: Steinhart – Hart, Coefficients, thiab Resistor Dividers

Kuv cov qauv tsim yav dhau los suav nrog NTC qhov ntsuas kub ntsuas siv cov txheej txheem saib rau kev hloov pauv qhov hluav taws xob nkag los ntawm tus tiv thaiv kev faib ua kom sov. Txij li ESP32 muaj peev xwm kaum ob lub tswv yim sib piv me me, thiab txij li thaum kuv tau tsim los kom raug qhov tseeb, kuv txiav txim siab los siv qhov "Steinhart-Hart" sib npaug hauv cov cai rau qhov hluav taws xob rau qhov hloov pauv kub.

Thawj zaug luam tawm xyoo 1968 los ntawm John S. Steinhart thiab Stanley R. Hart, Steinhart-Hart equation piav qhia qhov tsis kam ua kom sov kev sib raug zoo ntawm NTC qhov ntsuas kub raws li hauv qab no:

1 / T = A + (B * (cav (Thermistor))) + (C * cav (Thermistor) * cav (Thermistor) * cav (Thermistor))

qhov twg:

• T yog qib Kelvin.
• A, B, C yog Steinhart-Hart coefficients (ntau ntxiv nyob rau hauv ib pliag).
• Thiab Thermistor yog qhov ntsuas kub ntsuas qhov ntsuas kub tsis kam ntawm qhov kub tam sim no.

Yog li vim li cas qhov no zoo li nyuaj Steinhart-Hart equation tsim nyog rau qhov yooj yim NTC ntsuas kub raws tus ntsuas kub digital? Ib qho "zoo tshaj" NTC qhov ntsuas kub yuav muab cov kab tawm tsam tiv thaiv qhov kub thiab txias, yog li cov kab zauv yooj yim uas cuam tshuam nrog cov tswv yim hluav taws xob thiab ntsuas yuav ua rau muaj qhov ntsuas qhov tseeb. Txawm li cas los xij, NTC qhov ntsuas kub tsis yog kab thiab, thaum ua ke nrog cov tsis-linear analog input ntawm yuav luag txhua tus nqi qis ib tus txheej txheem txheej txheem xws li WiFi Cov Khoom 32, tsim cov khoom tsis-linear analog inputs thiab yog li tsis raug ntsuas kub. Los ntawm kev siv qhov sib npaug xws li Steinhart-Hart nrog rau kev ntsuas ntsuas kom zoo, ntsuas kub tau raug siv NTC ntsuas qhov ntsuas kub nrog tus nqi qis ib tus thawj coj ua haujlwm tuaj yeem ua tiav los ntawm kev ua kom ze ze ntawm qhov kub thiab txias.

Yog li rov qab mus rau Steinhart-Hart equation. Qhov sib npaug siv peb qhov sib npaug A, B thiab C txhawm rau txiav txim siab qhov kub raws li kev ua haujlwm ntawm thermistor tsis kam. Peb cov coefficients no los qhov twg los? Qee cov tuam txhab muab cov coefficients nrog lawv NTC qhov ntsuas kub, thiab lwm tus tsis ua. Tsis tas li ntawd, cov chaw tsim khoom muab cov coefficients yuav lossis tsis yog rau qhov ntsuas kub qhov tseeb uas koj tuaj yeem yuav, thiab feem ntau yuav yog tus sawv cev sib piv ntawm cov piv txwv loj ntawm txhua qhov ntsuas kub uas lawv tsim nyob rau lub sijhawm. Thiab thaum kawg, kuv yooj yim tsis tuaj yeem nrhiav cov coefficients rau qhov kev sojntsuam siv hauv qhov tsim no.

Tsis muaj qhov xav tau coefficients, Kuv tsim Steinhart-Hart Spreadsheet, daim ntawv nthuav dav raws lub laij lej uas pab tsim cov coefficients xav tau rau NTC ntsuas kub (Kuv poob qhov txuas rau lub vev xaib zoo li lub laij lej kuv siv ntau xyoo dhau los, yog li kuv tsim qhov no.). Txhawm rau txiav txim siab qhov coefficients rau qhov ntsuas kub, kuv pib los ntawm kev ntsuas tus nqi ntawm 33k resistor siv hauv qhov faib hluav taws xob nrog digital ohmmeter, thiab nkag tus nqi mus rau thaj chaw daj ntawm daim ntawv teev npe "Resistor". Tom ntej no, Kuv tso qhov ntsuas kub hauv peb qhov chaw ib puag ncig; thawj chav sov, dej khov thib ob thiab dej kub thib peb, nrog rau lub ntsuas kub paub qhov tseeb, thiab tso sijhawm rau qhov ntsuas kub ntawm tus pas ntsuas kub thiab cov ntsuas cua sov ntsuas suav nrog tshwm ntawm WiFi Kit 32 zaub (ntau ntxiv tom qab no) kom ruaj khov. Nrog rau qhov ntsuas kub thiab qhov ntsuas kub hauv lub ntsuas cua sov, kuv nkag mus rau qhov ntsuas kub tau paub los ntawm tus pas ntsuas kub paub tseeb thiab cov ntsuas cua sov tau tshwm ntawm cov zaub ntawm WiFi Kit 32 mus rau thaj chaw daj ntawm daim ntawv nthuav qhia "Degrees F from Thermometer" thiab "AD Suav los ntawm WiFi Cov Khoom 32 "feem, rau txhua ntawm peb qhov chaw ib puag ncig. Thaum txhua qhov kev ntsuas nkag mus, thaj chaw ntsuab ntawm daim ntawv nthuav qhia muab A, B thiab C coefficients xav tau los ntawm Steinhart-Hart equation uas tom qab ntawd yooj yim theej thiab muab tso rau hauv qhov chaws.

Raws li tau hais yav dhau los cov txiaj ntsig ntawm Steinhart-Hart equation yog qib Kelvin, thiab qhov kev tsim qauv no qhia txog qib Fahrenheit. Kev hloov pauv los ntawm qib Kelvin mus rau degrees Fahrenheit yog raws li hauv qab no:

Ua ntej, hloov qib Kelvin rau degrees Celsius los ntawm kev rho tawm 273.15 (degrees Kelvin) los ntawm Steinhart-Hart equation:

Qib C = (A + (B * (cav (Thermistor))) + (C * cav (Thermistor) * cav (Thermistor) * cav (Thermistor))) - 273.15

Thiab thib ob, hloov qib Celsius mus rau degrees Fahrenheit raws li hauv qab no:

Qib F = ((Qib C * 9) / 5) + 32

Nrog rau Steinhart-Hart equation thiab coefficients ua tiav, qhov sib npaug thib ob yog xav tau los nyeem cov resistor faib faib tawm. Ib tus qauv ntawm cov resistor divider siv hauv qhov tsim no yog:

vRef <--- Thermistor <--- vOut <--- Resistor <--- Hauv av

qhov twg:

• vRef hauv qhov kev tsim no yog 3.3vdc.
• Thermistor yog NTC qhov ntsuas kub ntsuas siv hauv qhov sib faib resistor.
• vOut yog qhov hluav taws xob tso tawm ntawm qhov sib faib resistor.
• Resistor yog 33k resistor siv hauv qhov sib faib resistor.
• Thiab hauv av yog, zoo, hauv av.

vOut ntawm qhov sib faib resistor hauv qhov tsim qauv no txuas nrog WiFi Kit 32 analog input A0 (tus pin 36), thiab qhov hluav taws xob qhov hluav taws xob ntawm cov resistor divider tau suav raws li hauv qab no:

vOut = vRef * Resistor / (Resistor + Thermistor)

Txawm li cas los xij, raws li tau sau tseg hauv Steinhart-Hart equation, tus ntsuas hluav taws xob tiv thaiv tus nqi yuav tsum tau txhawm rau kom tau txais qhov kub thiab txias, tsis yog qhov hluav taws xob tso tawm ntawm qhov sib cais resistor. Yog li rov kho qhov sib npaug kom tso tawm tus nqi thermistor yuav tsum siv me ntsis algebra raws li hauv qab no:

Sib npaug ob tog los ntawm "(Resistor + Thermistor)" ua rau:

vOut * (Resistor + Thermistor) = vRef * Resistor

Faib ob tog los ntawm "vOut" ua rau:

Resistor + Thermistor = (vRef * Resistor) / vOut

Rho tawm "Resistor" los ntawm ob sab ua rau:

Thermistor = (vRef * Resistor / vOut) - Resistor

Thiab thaum kawg, siv cov khoom faib khoom, yooj yim:

Thermistor = Resistor * ((vRef / vOut) - 1)

Hloov pauv WiFi Cov Khoom 32 A0 analog input suav ntawm 0 txog 4095 rau vOut, thiab hloov pauv tus nqi ntawm 4096 rau vRef, qhov sib npaug resistor faib qhov muab cov thermistor tiv taus tus nqi xav tau los ntawm Steinhart-Hart equation dhau los:

Thermistor = Resistor * ((4096 / Analog Input Count) - 1)

Yog li nrog lej tom qab peb, cia sib sau ua ke qee yam khoom siv hluav taws xob.

Kauj Ruam 2: Sib dhos Cov Khoom Siv Hluav Taws Xob

Txog cov khoom siv hluav taws xob, Kuv tau sau ua ke ESP32 Capacitive Touch demonstrator
