Ohun elo Examppẹlu Arduino Uno:

Pupọ julọ sẹẹli ni awọn okun onirin mẹrin: pupa, dudu, alawọ ewe ati funfun. Lori ọkọ HX711 iwọ yoo wa E +/E-, A +/A- ati B +/ Awọn asopọ. So sẹẹli fifuye pọ si igbimọ sensọ HX711 ni ibamu si tabili atẹle:

HX711 Fifuye sensọ Board Fifuye Cell Waya
E+ Pupa
E- Dudu
A+ Alawọ ewe
A- Funfun
B- Ti ko lo

HX711 Module nṣiṣẹ ni 5V ati ibaraẹnisọrọ ti wa ni ṣe nipa lilo ni tẹlentẹle SDA ati SCK pinni.

Nibo ni lati lo iwuwo lori sẹẹli fifuye?
O le wo itọka kan ti han lori sẹẹli fifuye. Ọfà yii fihan itọsọna ti agbara lori sẹẹli fifuye. O le ṣe eto ti o han ni nọmba nipa lilo awọn ila irin. So adikala irin lori sẹẹli Fifuye nipa lilo awọn boluti.

So sikematiki pọ bi o ṣe han ni Nọmba 1 loke.
Ni ibere fun module sensọ yii lati ṣiṣẹ pẹlu awọn igbimọ Arduino, a nilo Ile-ikawe HX711 eyiti o le gberu lati inu https://github.com/bogde/HX711.
Ṣaaju ki o to le ṣee lo HX711 lati wiwọn ohun kan ni iwọn deede, o nilo lati ṣe iwọntunwọnsi ni akọkọ. Igbesẹ isalẹ yoo fihan ọ bi o ṣe le ṣe isọdiwọn.
