And that’s where the HX711 breakout board comes in:  as it amplifies the weak signal to a few volts so that we can read the signal with the help of an Arduino Uno. Required fields are marked *. Fortunately, there exist many breakout boards for the HX711. Load cells are transducers that convert pressure/force into an electrical signal. but when i try to read your data (LoadCell.getData()) the number start in zero and increasing by yourself, i don’t have the same reaction like you. Wir bieten ein umfangreiches Mainboard-Sortiment mit erstklassigen Marken: von Raspberry Pi und Arduino über Olimex und ARM bis hin zu AVR und vielen weiteren. Between the screw and the load cell, there should be a nut, which serves as a protection to the board (see pictures). Using Two Load Cells in a Single Circuit. Good day Sir!

The module’s GND pin must be connected to the Arduino’s GND pin. 4 x 50kg (200 kg / 440 lbs). Without any further delay, let’s get started!!! A 24-bit analog-to-digital converter called the HX711 converts the small changes in strain from the load cell into 24-bit changes in voltage (Arduino 0-5V). Therefore, I used an alternative approach to calibrate my weighing scale. – LCM1602 IIC V1 (LCD) [Search on Aliexpress | Amazon | eBay.com] Versandkosten. Um EXP Tech in vollem Umfang nutzen zu können, empfehlen wir Ihnen Javascript in Ihrem Browser zu aktiveren. – Arduino Uno [Search on Aliexpress | Amazon | eBay.com] Ich denke mit ein paar Aluprofilen kann ich einen entsprechenden Rahmen zimmern, bei entsprechendem Gewicht auf der Zelle muss es ja stabil sein und darf nicht kippen (meine Wägezelle funktioniert bis 5kg). They should also be less than 64 characters long. ‘exit status 1 The HX711 module amplifies the low-voltage output of the load cell and sends it to the Arduino so that the Arduino eventually calculate weight from this data. Seeed Studio’s Arduino Sensor Kit—What’s new? The Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. A library to drive a HX711 load cell amplifier on a Raspberry Pi. As shown in circuit, for connecting the load cell to a microcontroller using HX711 we need a few more components. This report would have more information with 2 x 50kg (100 kg / 220 lbs). I need your help for my school project. Thank u sir. As the LCM1602 module requires also a connection to the 5V pin, a breadboard is used in-between to split the Arduino’s 5V signal. i’m from Brasil, Arduino: 1.8.12 (Windows Store 1.8.33.0) (Windows 10), Board: “Arduino Uno”, sketch_feb17a:7:53: error: ‘POSITIVE’ was not declared in this scope, LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // 0x27 is the i2c address of the LCM1602 IIC v1 module (might differ). Hello! The HX711 is a 24-bit analog-to-digital converter which fits perfectly to weight scale applications. The HX711 load cell amplifier is used to get measurable data out from a load cell and strain gauge. Auch im DIY-Bereich... Benötigen Sie noch einen Adapter oder ein geeignetes Netzteil für Ihren Single Board Computer? Load Cell (HX711) component. Oder möchten Sie in Ihrem DIY-Objekt ein Signallicht in Form einer LED einbauen? Learn how your comment data is processed. I have used 16*2 liquidcrystal dispaly..but the weighting value in display does not set to zero after the load is removed..plz help me out by clearing the display for 16*2 lcd diplay, Cannot get code to compile. SparkFun Load Cell Amplifier - HX711 SEN-13879 I thought the weight that show is increase double. Sketch names can only consist What about ESP32? 192 is a sample value float aLoad = 500; // your lowest load value for example 500 grams or use no laod and take that value as lowest. Durch die Messung (bzw. The HX711 and Load cell are used in building a weighing scale. Respected sir, By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. I'm seeing the exact same issue listed here -- I bought four of this load cell, and wired them up with a Sparkfun Combinator and a Sparkfun HX711 Breakout board. 1.1), Geschäftskunden und Bildungseinrichtungen, Weiß (Verstärker +, Signal + oder Ausgang +), Wählbare 10SPS oder 80SPS Ausgangsdatenrate, Gleichzeitige 50 und 60Hz Versorgungsunterdrückung. The load cells plug into this board, and this … This allows the Arduino to resolve weight (mass) changes down to the range of the load cell (typically 500g, … The HX711 break out board interfacing with the load cell and Arduino Uno or Mega. Hat sofort funktioniert (den LCD-Kram habe ich durch Ausgaben auf die serielle Schnittstelle ersetzt). The same program which is used in this tutorial can also run on Arduino Mega. Bitte beachten Sie, dass einige Wägezellen leichte Farbabweichungen aufweisen können. In this tutorial, it is shown how to utilize an Arduino Uno, a HX711 breakout board, and a load cell in order to measure weight.
