2 Lenaneo la Arduino UNO ho lekanya Boima ba 'mele ho KG:

Kopo Example Arduino Uno:

Bongata ba Load cell bo na le lithapo tse 'ne: tse khubelu, tse ntšo, tse tala le tse tšoeu. Ho boto ea HX711 u tla fumana E+/E-, A+/A- le B+/Bconnections. Hokela cell load ho HX711 sensor board ho latela tafole e latelang:

HX711 Load Sensor Board	Laola Cell Wire
E+	Khubedu
E-	Ntsho
A+	Botala
A-	Bosoeu
B-	E sa sebelisoeng
B+	E sa sebelisoeng

Sensor ea HX711	Arduino Uno
GND	GND
DT	D3
TS'ELISO	D2
VCC	5V

HX711 Module e sebetsa ho 5V mme puisano e etsoa ho sebelisoa li-serial SDA le SCK pin.

Ke hokae moo u ka sebelisang boima ba 'mele ho cell cell?
U ka bona motsu o bontšoa ho Load cell. Motsu ona o bontša tataiso ea matla seleng ea mojaro. U ka etsa tokisetso e bontšitsoeng setšoantšong u sebelisa marapo a tšepe. Hokela mohala oa tšepe holim'a Load cell u sebelisa liboutu.

Lenaneo la Arduino UNO ho lekanya Boima ba 'mele ho KG:

Hokela schematic joalokaha ho bontšitsoe setšoantšong 1 ka holimo.
E le hore mojule ona oa sensor o sebetse le liboto tsa Arduino, re hloka HX711 Library e ka theolang thepa ho tloha. https://github.com/bogde/HX711.
Pele HX711 e ka sebelisoa ho metha boima ba ntho ka nepo, e hloka ho lekanya pele. Ka tlase mohato o tla u bontša mokhoa oa ho etsa calibration.

Tlosa mojaro ofe kapa ofe ho sensor ea mojaro. Bula Serial Monitor. Fesetere e ka tlase e lokela ho buloa e bonts'ang mojule o hokahane ka katleho ho Arduino Uno.

Beha ntho e tsebahalang ea boima holim'a sele ea mojaro. Tabeng ena mongoli o sebelisitse boima bo tsejoang ba 191grams le 10KG Load Cell. Serial Monitor e tla bonts'a boima ba 'mele bo bontšitsoeng ka tlase:

Re hloka ho etsa calibration mona:

Senotlolo sa lengolo "a, s, d, f" sebakeng sa taelo ea serial monitor ebe o tobetsa konopo ea "Send" ho eketsa lintlha tsa calibration ka 10, 100, 1000, 10000 ka ho latellana.

Tsoela pele ho fetola ho fihlela 'malo o bonts'itsoeng boima ba' nete bo behiloeng seleng ea mojaro. Rekota boleng ba "calibration_factor", ntlheng ena "-239250" ho boima ba sengoli ba 191g le 10KG Load Cell.

Kamora ho kenya sekhechana ka katleho, bula Serial Monitor. Fesetere e ka tlase e lokela ho hlaha e bonts'a boleng ba tekanyo ea 'nete:

U ka seta bocha ho bala ho 0.000kg (ntle le mojaro") ka ho kenya "t" kapa "T" sebakeng sa taelo ebe o tobetsa konopo ea "Romela". Pontšo e ka tlase e bonts'ang boleng ba tekanyo e fetoha 0.000kg.

Beha ntho holim'a sele ea mojaro, boima ba sebele bo lokela ho bonts'a. Ka tlase ke pontšo ea boima ha u beha ntho ea 191grams (e sebelisoang mohatong oa 1 bakeng sa ho lekanya).

Hooray! o entse sekala sa ho bekha ka ho nepahala ha lintlha tse tharo tsa lidesimali!
