@Tom We used Jumper Wires soldered to the load cell leads.
hello I bought this shield for Arduino and i had load the code but I want know which units of force deployed in the serial monitor
@Rene If you are using this library, you will obtain two values on the serial monitor. The first one is the Raw ADC value (should be from 0 to 1023) and the second is the calculated force. The unit of the calculated force will depend on your load cell capacity range. In the example provided, we used a load cell of 1Kg capacity. Therefore, the output range is 0 to 1 Kilograms (WheatstoneBridge wsb_strain1(A0, 365, 675, 0, 1000);). So, the calculated force value will be in grams.
If I have a 5kg load cell max can then modify the code for 0-1000 0-5000? and what happens if I change the analog values 365 and 675?
@Rene 365-675 is the ADC range (365 is the min ADC value and 675 is the max ADC value). You can determine these values by connecting your Load Cell (with the Wheatstone Shield and Arduino) and do an analog read with no load then with a near capacity load. The values obtained will be your ADC range. You are correct, with a 5Kg load cell, you can modify the code (0-5000) so that you obtain the applied force in grams. The WheatstoneBridge wsb_strain1 function will do a linear interpolation between your ADC range and the force range on stain 1 (Analog 0 input).
Hi,
Iām working in one project and i want some value display on LCD (Kg) using load cell ,plz explain the hole process and arduino coding for load cell?
HI, sir i am use arduino ,āhow to calibrate hx711 with 5kg or100g or 150g and 200g loadcell,sor please send me code for this process?
@imran As we previously mentioned, you can find the wiring instructions and the Arduino library to connect the LCD shield and calibrate the load cell in this blog post.
I have a typical load cell and need to amplify the signal. I have a 9v input and my output is 1mV/V. I am trying to read the signal with a ACC-68M Delta Tau PLC which has an input range of 0-10V. So simply, I want to amplify my output signal from the load cell to 0-9v from 0-9mV. Will this work for me? (assuming I set the gain to 1000x with the right resistors).
@Matt The strain inputs on the Strain Gauge Shield is 3.3V excited. Therefore, the analog output from the shield ranges from 0 to 3.3V.
Sir,I need to connect arduino due with ina125p to interface load cell is it possible
@venkataramanaa Please take a look at these forum posts :
Load cell with INA125P
Load cell, INA125P AnalogReference, signal stability
If i wanted to measure bending and tensile stress with temperature compensation, what configuration would i use. and how many possible gauges can i read on the same Arduino?
@Ian The Wheatstone Shield is intended to be interfaced with 2 x Load Cells which will measure force (weight). We canāt think of a way to use the shield to measure bending with temperature compensation of a material.
Hi there,
Iām doing a home project, which, as i planned it, needs a set of load cells and amplifiers.
In my opinion, this is a really nice set up comparing to other i have considered and i like it for the fact that itās a shield and is a lot easier to use than the HX711 breakout amplifier, according to what iāve read about both.
There is still one concern that i just canāt wrap my mind around:
if i only want to use one load cell, will it work with this shield?
Because from what i have read about load cells, Wheatstone Bridge based circuit needs 2 load cell working together, right?
Please if anyone can help me, itād be really nice.
Thank you.
@Ben Yes you can use one load cell with RB-Onl-38 shield. The Wheatstone Bridge Circuit is the basis of a load cell.
The shield is intended to amplify the output signal of the Wheatstone Bridge/Load Cell you will use. With this shield, you can interface and amplify two load cells separately through Strain1 and Strain2 inputs.
I am just wondering if i can get your opinion and possibly some help on and idea i am working on. I want to use off the shelf components to build a automated storage and retrieval system that will weigh the items going in and read the rfid. this will register the weight of the box and store it to a database. A robotic arm will take the box and store it to a free location, when the item is retrieved the database will know the location and remove it from the storage area and remove it from the database. I have no idea where to startā¦can anybody help?
@Len The question does not seem to relate at all to this article and as such we encourage you to create a new topic on the RobotShop Forum
Hi,
Thank you for posting all this, this is very helpful. I was wondering if there is a way of testing how linear this load cell amplifier shield. Do you guys have any ideas as to what to connect to this shield that for example we can trust is outputting 2milivolts very very accurately and then say with a gain of 495 on the shield we should be reading 1 volt from the arduino and that therefore the shield is very linear.
Thanks a lot
