Video: Kev Sib Hloov Roj Sensor Nrog Arduino: 4 Cov Kauj Ruam
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24
MQ-2 cov pa luam yeeb nkag tau rau haus luam yeeb thiab rau cov pa hluav taws hauv qab no:
LPG, Butane, Propane, Methane, Cawv, Hydrogen. Qhov tsis kam ntawm lub ntsuas cua sib txawv nyob ntawm seb hom roj. Cov pa luam yeeb muaj lub zog tsim hluav taws xob uas tso cai rau koj hloov kho lub ntsuas hluav taws xob kom raug raws li qhov tseeb koj xav tshuaj xyuas roj.
Kauj Ruam 1: Nws Ua Haujlwm Li Cas?
Qhov hluav taws xob uas lub ntsuas hluav taws xob tso tawm hloov pauv raws li qib pa taws/pa roj uas muaj nyob hauv huab cua. Lub ntsuas hluav taws xob tso tawm qhov hluav taws xob uas sib piv rau cov pa taws/pa.
Hauv lwm lo lus, kev sib raug zoo ntawm qhov ntsuas hluav taws xob thiab cov pa roj yog qhov hauv qab no:
- Qhov ntau dua cov roj concentration, qhov ntau dua qhov tso tawm qhov hluav taws xob
- Qhov qis roj concentration, qhov qis dua qhov tso tawm qhov hluav taws xob
Kauj Ruam 2: Cov Cheeb Tsam Yuav Tsum Tau:
Cov khoom siv xav tau yog:
1. Arduino UNO
2. Cov qhob cij
3. Gas Sensor
4. Buzzer
5. LED cov
6. Cov neeg tiv taus (220 ohms)
7. Jumper xov hlau
Kauj Ruam 3: Daim Duab Circuit:
Ua ntej ua qhov sib txuas ntawm Gas sensor:
1. Txuas B1, H2 & B2 mus rau 5v ntawm Arduino thiab H1 ncaj qha rau hauv av.
2. Txuas lub 220-ohm resistor rau A2 thiab txuas rau lwm qhov kawg rau gnd.
3. Txuas A1 rau analogPin A0.
Tam sim no ua qhov sib txuas rau coj thiab buzzer:
1. Txuas lub 220-ohm resistor mus rau qhov tsis zoo ntawm txhua tus coj thiab lwm qhov kawg ntawm cov resistors rau gnd.
2. Txuas cov ceg zoo rau digitalPin ntawm Arduino piv txwv li 2, 3 & 4.
3. Txuas cov lus tsis zoo ntawm lub tswb nrov rau gnd thiab txhais ceg zoo rau digitalPin 5.

Siv rau Cov Roj Tsheb Tuag thiab Cov Roj Ua Roj Roj Ua Ntej: Ntau lub roj teeb tsheb "tuag" yog cov roj teeb zoo tiag tiag. Lawv tsuas yog tsis tuaj yeem muab ntau pua qhov amps xav tau los pib lub tsheb. Ntau "tuag" kaw cov roj teeb kua qaub ua tau yog cov roj teeb uas tsis tau tuag uas tsis tuaj yeem ntseeg tau ntxiv
Yuav Txhais Li Cas Kev Taw Qhia ntawm Kev Hloov Los Ntawm Digital Hloov Hloov Nrog PIC: 5 Cov Kauj Ruam
Yuav Ua Li Cas Txhais Tus Cwj Pwm ntawm Kev Sib Hloov Los Ntawm Digital Rotary Hloov Nrog PIC: Lub hom phiaj rau Cov Lus Qhia no yog los piav qhia yuav ua li cas txhawm rau cuam tshuam cov digital (plaub kab cim coded) hloov pauv nrog lub microcontroller. Tsis txhob txhawj, kuv yuav piav qhia dab tsi? Quadrature coded? txhais tau rau peb. Lub interface no thiab cov software txuas nrog wilâ € ¦
