Taw qhia:

Lub hom phiaj ntawm qhov kev sim no yog siv lub ntsuas pH nrog Arduino uno txhawm rau ntsuas qhov ntsuas hluav taws xob ntawm cov kais dej, kua txiv, thiab Roob Dej Dej haus raws li tus qauv ntxiv ntawm Himalayan liab ntsev ntsev ntxiv. Lub hom phiaj tsis yog tsuas yog saib yuav ua li cas ntxiv ntsev rau cov kua cuam tshuam rau pH tab sis kuj yuav ua li cas nws hloov qhov hluav taws xob.

Khoom siv

1. Arduino ib
2. pH meter thiab pH sensor board
3. qee cov kua (Kuv siv cov kais dej, kua txiv hmab txiv ntoo, thiab cov lwg roob)
4. Ntsev (txhua lub rooj ntsev zoo)
5. Ib qho ntsuas ntsuas rau tus qauv ntxiv (Kuv siv 1/8 tsp)
6. Qee lub khob rau cov kua
7. jumper cables (Txiv neej rau poj niam lossis poj niam rau poj niam)
8. Khoos phis tawj nrog Arduino program
9. Tsis daws teeb meem - yog ua tau

Kauj ruam 1: Teeb Koj Arduino

1. Txhawm rau txuas koj Arduino mus rau lub ntsuas phoo sensor koj yuav xav tau:

   • Txuas PO aka pH analog input rau Arduino A0

   • Txuas Gnd rau Arduino Gnd

     Qhov no yog txhawm rau ntsuas qhov ntsuas pH

   • Txuas lwm Gnd rau Arduino Gnd

     Qhov no ua rau cov laug cam

   • Txuas VCC (5V DC) rau Arduino 5V
   • Kuv siv poj niam rau poj niam jumper xov hlau

Kauj ruam 2: Code

Siv cov cai no qiv los ntawm kev xa mus rau koj Arduino

Kauj Ruam 3: Ntsuam Xyuas Koj Li (Yog Ua Tau)

Koj yuav tsum ntsuas koj qhov ntsuas pH kom nws nkag siab tias 2.5 V qhia tias tsis muaj pH nruab nrab, 5.0 V qhia txog kev daws teeb meem yooj yim thiab 0 V yog acidic heev. Ntawm lub rooj tsav xwm pH siv ntawm no nws yooj yim heev ua.

Txhua yam koj xav tau kev daws teeb meem uas koj paub yog qhov nruab nrab, zoo li dej. Kuv siv pH 7.0 PO4 tsis tov

Ntxig koj qhov kev sojntsuam rau hauv dej, khiav lub tshuab saib. Yog tias nws tsis nyeem kwv yees li 2.5 V, tom qab ntawd yuav tsum tau kho lub hwj chim.

Yog tias koj muaj lub taub hau me me ntsia hlau nyob ib puag ncig, kho cov ntsia hlau rau ntawm lub hwj chim xiav ze rau BNC interface. Kho nws kom txog thaum ntsuas saib tau nyeem kwv yees li 2.5 V thiab koj zoo mus

Kauj Ruam 4: Xeem Koj Cov Kev Ntsuas

Yog tias koj muaj pH cov kev daws teeb meem los ntsuas, ua cov thawj ua qhov kev tswj hwm kom ntseeg tau tias koj tau txais qhov hluav taws xob uas ua rau muaj kev nkag siab rau pH ntawm qhov tsis nyob.

1. Rau lub khob me me, ntxiv 1/4 khob dej
2. Ntxig rau qhov ntsuas pH
3. Siv cov ntsuas ntsuas los ntsuas qhov hluav taws xob. Muab nws li 30 vib nas this lossis ua ntej txiav txim siab koj tus nqi kawg
4. Tshem tawm qhov ntsuas pH thiab muab tso rau hauv ib khob dej cais kom tuav nws nyob nruab nrab ntawm kev khiav
5. Siv 1/8 tsp, ncuav ntsev ntsev rau hauv lub khob dej. Ua kom zoo tshaj qhov koj ua tau. Kuv pom tias qhov ntsev ntsev himalayn tsis yaj zoo li koj cov ntsev ntsev dawb, tab sis qhov ntawd zoo.
6. ntxig qhov sojntsuam rau hauv dej nrog ntsev
7. Rov ua cov kauj ruam 3-6 kom txog thaum koj tau tso 0.5 tsp ntsev liab ntsev rau hauv kev daws.
8. Nws raug nquahu kom koj tseem mus nyeem qhov tseeb pH tom qab txhua qhov ntxiv ntsev. Kuv tsuas yog siv qee cov kab ntawv pH tab sis koj tuaj yeem nrhiav lwm cov duab thiab cov lej rau program koj Arduino txhawm rau ntsuas pH.

Nov yog cov vis dis aus luv luv ntawm cov theem pib ntawm kev ntsuas qhov hluav taws xob nrog tus qauv ntxiv ntawm ntsev ntsev

Kauj Ruam 6: Txheeb Xyuas Cov Ntaub Ntawv

Kuv tau kaw qhov ntsuas hluav taws xob rau cov kais dej, kua txiv hmab txiv ntoo, thiab Dej Roob

Txhawm rau nrhiav pH ib qhov hluav taws xob txhua yam koj ua yog faib qhov ntsuas pH ua ntej muaj ntsev ntxiv / tso zis hluav taws xob los ntawm Arduino. Koj tseem tuaj yeem google google pH ntawm qhov kev daws teeb meem yuav tsum yog.

Kuv kuj tau mus tom ntej thiab suav qhov % yuam kev rau cov kais dej. (Kuv tsis tau ua nws rau lwm yam dej qab zib).

Koj tuaj yeem siv koj cov ntaub ntawv los ntawm cov kais dej los tsim qhov ntsuas nkhaus, pom ntawm no ib yam nkaus. Lwm qhov kev tshuaj xyuas cov ntaub ntawv kuj tau ua tiav, raws li pom hauv Excel daim ntawv nthuav qhia

Kauj Ruam 7: Cov peev txheej

Cov peev txheej kuv siv rau kev tshoov siab
