ARDUINO HX711 Ma'aunin Ma'aunin Sensors ADC Module Manual
Aikace-aikace Exampda Arduino Uno:
Yawancin Load cell yana da wayoyi huɗu: ja, baki, kore da fari. A kan allon HX711 za ku sami E+/E-, A+/A- da B+/Bconnections. Haɗa tantanin halitta zuwa allon firikwensin HX711 bisa ga tebur mai zuwa:
| HX711 Load Sensor Board | Load da Wayar salula |
| E+ | Ja |
| E- | Baki |
| A+ | Kore |
| A- | Fari |
| B- | Ba a yi amfani da shi ba |
| B+ | Ba a yi amfani da shi ba |
| Saukewa: HX711 | Arduino Uno |
| GND | GND |
| DT | D3 |
| SCK | D2 |
| VCC | 5V |
HX711 Module yana aiki a 5V kuma ana yin sadarwa ta amfani da serial SDA da SCK fil.
Inda za a yi amfani da nauyi akan tantanin halitta?
Kuna iya ganin ana nuna kibiya akan Load cell. Wannan kibiya tana nuna alkiblar karfi a kan tantanin halitta. Kuna iya yin tsari wanda aka nuna a cikin adadi ta amfani da ɗigon ƙarfe. Haɗa tsiri na ƙarfe akan Load cell ta amfani da kusoshi.
Shirye-shiryen Arduino UNO don auna nauyi a KG:
Haɗa tsarin kamar yadda aka nuna a hoto na 1 a sama.
Domin wannan tsarin firikwensin ya yi aiki tare da allon Arduino, muna buƙatar ɗakin karatu na HX711 wanda zai iya sauke kaya daga https://github.com/bogde/HX711.
Kafin a iya amfani da HX711 don auna abu daidai, yana buƙatar daidaitawa da farko. A ƙasa mataki zai nuna maka yadda za a yi calibration.
