[image] bdaouas: are planning to use external analog voltage reference Great! Thank you for your quick response :slight_smile:

hello, I am trying to connect the amplifier to an Arduino NANO, but I cannot get it to work. I connected the strain1 to A0, strain2 to A1, and then Vin, GND and 5V to the respective connectors, but it is not working like it says it should according to the test procedure (PDF fi…

Please connect 3.3V from the Arduino Nano to the 3.3V pin of the load cell shield as the circuitry on the load cell shield (and the load cell excitation pin) is powered through the 3.3V pin. You can also power the shield with 5V by connecting 5V output from Arduino Nano to the 3.…

Thank you for the quick response! That worked perfectly. One more question, I am trying to connect a half-bridge strain gauge to the shield, but I am not sure which pins to connect it to. Could you help me with it? Thanks again. Pablo

hello, I am trying to connect the shield to a quarter bridge strain gauge but when I apply the voltage, the current is too high (and has burned the arduino). I checked the wiring a few times and I think it is properly set (with 3 dummy resistances and the load resistance). Is t…

What is the resistance values of the resistors and the strain gauge ? How was your bridge powered ? Could you provide a wiring diagram of your bridge ?

I tried two different setups (shown in the pictures); the strain gauges have a nominal value of 1k. I think there was a mismatch between the shield datasheet and the webpage of strain gauges configuration given at the site. I checked with different tests and got it to kinda work…

The gain of the AD8426 instrumentation amplifier IC is set to 495 by default on the shield with the gain resistor Rgain = 100 Ohms. A voltage input from the wheatstone bridge of 1.4V or 3V will saturate the output of the amplifier. You probably need to remove the gain resistor fo…

Hello, everybody, I have been working on a load readout device using load cell 0-300kg with an excitation of 10V and an output of 2mV/V. I have searched the internet and have found 2 ways of doing it first with HX711 amplifier second with load cell shield or nanoshield (company …

Hi, The HX711 Load Cell Amplifier is a single channel amplifier with a digital interface output and provides a 24 bit resolution which is higher than the Arduino’s 12 bit. However, the data output rate only goes to a maximum of 80Hz. The Load Cell / Wheatstone Amplifier Shield i…
