ARDUINO HX711 Weighing Sensors ADC Module Mushandisi Manual
Application Examppamwe neArduino Uno:
Yakawanda Load cell ine waya ina: tsvuku, nhema, girini uye chena. PaHX711 board unowana E+/E-, A+/A- uye B+/Bconnections. Batanidza mutoro cell kuHX711 sensor board zvinoenderana netafura inotevera:
| HX711 Load Sensor Board | Rodha Cell Wire |
| E+ | Tsvuku |
| E- | Nhema |
| A+ | Girinhi |
| A- | Chena |
| B- | Zvisina kushandiswa |
| B+ | Zvisina kushandiswa |
| HX711 Sensor | Arduino Uno |
| GND | GND |
| DT | D3 |
| SCK | D2 |
| VCC | 5V |
HX711 Module inoshanda pa5V uye kutaurirana kunoitwa uchishandisa serial SDA uye SCK pini.
Ndekupi kwekuisa huremu pane mutoro cell?
Unogona kuona museve unoratidzwa paRoad cell. Museve uyu unoratidza mafambiro esimba pasero rinotakura. Iwe unogona kuita kurongeka kunoratidzwa mumufananidzo uchishandisa simbi mitsetse. Batanidza simbi strip paRoad cell uchishandisa mabhaudhi.
Kuronga Arduino UNO kuyera uremu muKG:
Batanidza schematic sezvakaratidzwa muFigure 1 pamusoro.
Kuti iyi sensor module ishande nemabhodhi eArduino, tinoda HX711 Library iyo inogona kudzika kubva https://github.com/bogde/HX711.
HX711 isati yagona kushandiswa kuyera chinhu nemazvo, inoda kutanga yatanga. Pazasi nhanho inokuratidza maitiro ekuita calibration.

Bvisa chero mutoro kubva kune mutoro sensor. Vhura iyo Serial Monitor. Iro hwindo riri pazasi rinofanirwa kuvhurwa richiratidza iyo module yakanga yabudirira kubatana neArduino Uno.
Isa chinhu chinozivikanwa uremu pamutoro sero. Muchiitiko ichi munyori akashandisa huremu hunozivikanwa hwe191grams ne10KG Load Cell. Iyo Serial Monitor icharatidza humwe huremu sezviri kuratidzwa pazasi:
Tinofanira kuita calibration pano:
- Kiyi mutsamba ” a, s, d, f ” mu serial yekutarisa nzvimbo yekuraira uye baya "Tumira" bhatani kuti uwedzere calibration factor ne10, 100, 1000, 10000 zvakateerana.
- Kiyi mutsamba ”z, x, c, v ” mune serial yekutarisa nzvimbo yekuraira uye rova bhatani rekuti "Tumira" kudzikisa calibration factor ne10, 100, 1000, 10000 zvakateerana.
Ramba uchigadzirisa kusvika kuverenga kunoratidzwa huremu chaihwo hwakaiswa pamutoro sero. Rekodha pasi kukosha kwe "calibration_factor", mune iyi kesi "-239250" mune uremu hwemunyori hwe191g referensi ne10KG Load Cell. Tichada kukosha uku kuti tibaye mune yedu yechipiri sketch yeyero chaiyo.

Mushure mekubudirira kurodha sketch, vhura Serial Monitor. Iro hwindo riri pazasi rinofanirwa kuoneka richiratidza kukosha chaiko kuyerwa:
Iwe unogona kuseta zvakare kuverenga kune 0.000kg (pasina mutoro") nekiyi-mu "t" kana "T" munzvimbo yekuraira uye rova bhatani rekuti "Tumira". Pazasi chiratidziro chinoratidza kukosha kwechiyero kuve 0.000kg.
Isa chinhu pamutoro sero, huremu chaihwo hunofanira kuratidza. Pazasi pane huremu kuratidza kana isa chinhu che191grams (chinoshandiswa mukutanga nhanho yekuenzanisa).
Hooray! wagadzira kuyeresa nekururama kwedesimali point mitatu!
