Question 1

Why does my KS-36 load-cell setup overload when I feed Arduino 5 V into the 9 V battery connector, and what’s the correct wiring to stop the ~30/1024-count zero drift? I’m building a force/torque ...

Question 2

I am looking to replace this single beam load cell with a tolerance of 50kg. The load cell height is 6.5cm. Sadly the company no longer provides this load cell. What would be a good substitute for ...

Question 3

I am designing an interface to read a VPG Force Sensor p/n 60001-500L-A1-00 with a BeagleBone Black Rev C using I2C interface to a Nuvoton NUA7802 ADC. I am having real trouble figuring out some of ...

Question 4

After some insight to why 4 half-bridge load cells connected parallelly to one ADC is superior to 4 full-bridge load cells in the same way. I have been informed that the difference in cost of both ...

Question 5

I'm working on a project that involves an ADC located on a separate PCB, which connects to a mainboard. There's also another PCB in the system that's dedicated to a motor driver. When the motor is ...

Question 6

I am working on a research project, where we need to measure a small amount friction during a high speed orbital motion (up to 400 Hz). The plan is to two load cells in X and Y direction, which output ...

Question 7

In the sample schematics and reference designs for HX711 I could find online, the values of R1 is always larger than R2. I cannot understand why - perhaps, I am on the wrong track. According to ...

Question 8

I thinking of to connect a 10VDC load cell to HX711 IC. Since the AVDD is maximum 5.5V, I cannot supply the power to the load cell from HX711. So, my idea to connect another 10V power supply to the ...

Question 9

I need to measure an output of a load cell (10VDC, 4 wires: red, black, green, white). My main MCU is ESP32 S3. My idea is to use something like ADS1231 or HX711 - preferably HX711. According to data ...

Question 10

I bought four 5 kg load cells (link) and connected them all together (all white cables, all green cables, etc.). Then I hooked them up to the HX711: When I read the values from the Arduino using the ...

Question 11

I am working on an acquisition system, which measures tension and compression in a load cell. I amplify the signal with the Instrumentation Amplifier INA128P, and after that I connect it to the ...

Question 12

I've been looking into various electronic components and noticed rampant 5%, 10%, and even 20% tolerances and accuracies not only in basic components such as capacitors, inductors, and resistors, but ...

Question 13

Context I'm using an I2C based Load Cell the FX29. I have been having troubles where the I2C sensor does not give me any data unless I manually unplug and replug the sensor while the Arduino sample ...

Question 14

I'm studying a solution for a weight measuring system that's affected by enviroment vibration - a load cell fixed on a "shaky" frame. My first thought was to use a 3-axis accelerometer (or ...

Question 15

I have a 100 gram load cell with the hx711 amplifier board. I have it wired up to an arduino nano with an NRF24L01 module to send the raw value to another arduino nano. The problem is that when I aply ...
