2 Kupanga Arduino UNO kuyeza Kulemera mu KG:

Ntchito Exampndi Arduino Uno:

Maselo ambiri a Load ali ndi mawaya anayi: ofiira, akuda, obiriwira ndi oyera. Pa bolodi la HX711 mupeza E+/E-, A+/A- ndi B+/Bconnections. Lumikizani cell load ku HX711 sensor board molingana ndi tebulo ili:

HX711 Load Sensor Board	Kwezani Cell Waya
E+	Chofiira
E-	Wakuda
A+	Green
A-	Choyera
B-	Zosagwiritsidwa ntchito
B+	Zosagwiritsidwa ntchito

Chithunzi cha HX711	Arduino Uno
GND	GND
DT	D3
SCK	D2
Chithunzi cha VCC	5V

HX711 Module imagwira ntchito pa 5V ndipo kuyankhulana kumachitika pogwiritsa ntchito zikhomo za SDA ndi SCK.

Momwe mungayikitsire zolemetsa pa cell cell?
Mutha kuwona muvi ukuwonetsedwa pa Load cell. Muvi uwu ukuwonetsa komwe mphamvu ikupita pa cell cell. Mutha kupanga makonzedwe owonetsedwa pachithunzichi pogwiritsa ntchito mizere yachitsulo. Gwirizanitsani chingwe chachitsulo pa Load cell pogwiritsa ntchito mabawuti.

Lumikizani schemamu monga momwe tawonetsera pa Chithunzi 1 pamwambapa.
Kuti gawo la sensali ligwire ntchito ndi matabwa a Arduino, tikufuna HX711 Library yomwe imatha kutsitsidwa kuchokera https://github.com/bogde/HX711.
HX711 isanagwiritsidwe ntchito kuyeza chinthu molondola, pamafunika kuyesa kaye. Pansipa sitepe ikuwonetsani momwe mungapangire calibration.

Chotsani katundu aliyense kuchokera ku sensa ya katundu. Tsegulani Serial Monitor. Zenera pansipa liyenera kutsegulidwa lomwe likuwonetsa kuti gawoli lidalumikizidwa bwino ndi Arduino Uno.

Ikani chinthu chodziwika cholemera pa selo yonyamula katundu. Pachifukwa ichi wolemba adagwiritsa ntchito kulemera kodziwika kwa 191grams ndi 10KG Load Cell. The Serial Monitor iwonetsa zolemera monga zikuwonetsedwa pansipa:

Tiyenera kuchita calibration apa:

Kiyi mu chilembo "a, s, d, f " mu serial monitor danga ndikudina "Tumizani" batani kuti muwonjezere kuchuluka kwa 10, 100, 1000, 10000 motsatana.

Kiyi mu chilembo "z, x, c, v " mu serial monitor space space and hit "Send" batani kuti muchepetse calibration factor ndi 10, 100, 1000, 10000 motsatana.

Pitirizani kusintha mpaka kuwerenga kuwonetsedwe kulemera kwenikweni komwe kumayikidwa pa cell cell. Lembani mtengo wa "calibration_factor", pamenepa "-239250" mu kulemera kwa wolemba 191g ndi 10KG Load Cell. Tidzafunika mtengowu kuti tilowe muzojambula zathu zachiwiri kuti tiyese zenizeni.

Gawo lachiwiri: Khodi Yomaliza Yoyezera Kulemera Kwambiri
Tisanakweze chojambulacho, tiyenera kulumikiza "calibration factor" yomwe yapezeka mu gawo loyamba:

Kwezani chojambula pansipa ku Arduino Uno Board, mutasintha masikelo:

Mutatha kukweza chithunzicho, tsegulani Serial Monitor. Zenera ili m'munsili liyenera kuwoneka likuwonetsa mtengo weniweni wa kuyeza:

Mutha kubwezeretsanso kuwerenga ku 0.000kg (popanda katundu") polemba "t" kapena "T" mumalo olamula ndikudina "Tumizani" batani. Pansipa chiwonetsero chomwe chikuwonetsa kuchuluka kwake kumakhala 0.000kg.

Ikani chinthu pa cell yolemetsa, kulemera kwenikweni kuyenera kuwonetsedwa. Pansipa pali chowonetsera cholemera mukayika chinthu cha 191grams (chogwiritsidwa ntchito mu sitepe yoyamba kuti muyike).

Uwu! mwapanga sikelo yoyezera molondola ndi mfundo zitatu za decimal!
