The HX711 is 24 bit ADC, which can find tiniest flex due to weight on the load cell. Leave the load cell connected to E+ E-You must power the HX711 with 5volt (or at least the ~4.6volt the WeMos provides on the 5volt pin). (adsbygoogle = window.adsbygoogle || []).push({}); We built a system that uses eight air-clamping cylinders (McMaster-Carr 62185K64) to push down on a piece of glass to seal it to a sidewall. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. * The INA125 is a low power, high accuracy instrumen- tation amplifier with a precision voltage reference. This is the 5 Kg Micro Load Cell. you have IAREF shorted to ground …. Music was controlled by using Pure Data to read the Arduino board and generate a midi-controller to use in Ableton Live. The following video shows the entire process for connecting the load cell to the amplifier board, then attaching the jumper wires to the amplifier board and connecting it to the Arduino MEGA2560. The micro load cell has a compensated temperature range: -10 to +40 °C and an operating temperature range: -20 to +55 °C. It has a capacity of 5 kg and a size of 55.25 x 12.7 x 12.7mm. digitalWrite(Buzzer,LOW); Usable for many different instrumentation amplifications, I am using the 5V of the Arduino board as exitation to the load cell, not the 5v-ref on the chip, Using a 1760 kg load cell I was able to sense 0.1 kg changes, You may have to swap the voltage applied to the bridge to get a decent range on the analog signal, Measure the output voltage (input to analog 0) while you change your load, and adjust the gain until you get a good sense. //put the following code after void loop() { int analogValue = analogRead(0); if (analogValue > 30) // change this value depends on your need Over the years, many RobotShop customers have asked us about the easiest way to interface a load cell with an Arduino board so they can get accurate weight measurements. Load Cells and Arduino Library 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). Hi Karthick, Using VISA is still an option, there are some good arduino softwares out there that do print the output of HX711 to serial port, and you can edit the code to add a key to the printed string (e.g. The output can be monitored on the Serial monitor of Arduino IDE. The load cells plug into this board, and this board tells the Arduino what the load cells measure. The load cells are commonly used in industrial processes where the weight of certain products is measured. In this tutorial we will see how to connect, calibrate and display the weight on a small OLED display, and by using a rotary encoder we will be able to change the units from: grams, kg or pounds. The HX711 load cell amplifier is used to get measurable data out from a load cell and strain gauge. Is it possible to use load cell as a sensor? B = 30 kg, // read the analog value showing (this is analogvalA), // analog reading taken with load A on the load cell, // analog reading taken with load B on the load cell, // Upload the sketch again, and confirm, that the kilo-reading from the serial output now is correct, using your known loads, // running average - We smooth the readings a little bit, // using a custom map-function, because the standard arduino map function only uses int. So once you have established two data pairs, you can interpolate the rest. In this Arduino Tutorial we are interfacing 40Kg load cell to the Arduino using the HX711 Load cell amplifier module.HX711 is a precision 24-bit analog to digital converter (ADC) designed for weighing scales and industrial control applications to interface directly with a bridge sensor. Connect load cell pins to the instrumentation amplifier as shown in the schematic diagram. The strain gauges are resistors that change their resitance when they are bent. In this example A = 10 kg. Strain Gauge Load Cells. using GML692 Sensor example code, circuit, pinout library This circuit should show you how: Sailing around the harbour in the summer of 2010 in a bathtub - Usually a bit more decently dressed. Scale is designed with -+0.01kg accuracy and switches are used to calibrate digital weight scale. Therefore, I do not have a “known weight” to calibrate the code since I am not using this for its intended purpose of a weight scale load cell. Many electronic circuits and microprocessor or microcontroller require a source …, Is your Project design needs color light sensing? if i want to display the weight in an LCD (16X2 ) screen what would be the code ? Hi, can i combine readings from 4 load cells and use the average as my final reading. What amplifier i must use for get better precision, HX712 or INA125? There is actually a load cell sitting inside any digital weight you can find. You need some sort of microvolt amplifier to read the minute change in volt over the bridge.ina125P – An IC that does it all for you. Going over the maximum limit can permanently damage the load cells. You can buy relatively cheap bathroom scale load cells from China. They come with a wide variety of weight ranges, starting from one kilogram up to a couple of hundred kilograms. Interfacing a Load Cell with Arduino The output signal produced by the load cell is in range of millivolts, so we need an amplifier to convert the signal into a level that we can later transform it into a digital signal and process it.
