Web6 de mai. de 2024 · My solution is to put an Op-amp as a comparator and amplifier (gain of 5 to 10 would be enough for me) between my sensor and the Arduino. ... Try a value of 10x the value of the Wheatstone bridge resistors. You might not need to if you power the sensor from E+ and E- of the HX711 (you should).

WebAnswer (1 of 5): Let me first ask why you want to amplify the voltage by 1000. Wait, let me reason it out. A strain gauge is typically 1mV/V, so if you supply it with 5V excitation, the maximum output is 5mV. You want to amplify this up to 5V - why? To drive an ADC, obviously. However, to amplif... Web21 de mar. de 2024 · Mar 21, 2024. #1. Hi, I'm trying to make a thermometer using a thermistor in a Wheatstone bridge going to an LM741. However, whilst I'm getting an output of roughly 1.5v from the op amp, it doesn't change with temperature or the variable resistor changing. The fixed resistors are 330k and the variable goes up to 100k and is in … greg champeau bankruptcy law

Web25 de fev. de 2012 · Feb 13, 2012. #2. You mention a 741. It is one of the oldest op amps created for an IC. It's specs are among the worst you can find. The reason this matters is stability. You are using a Cadillac of a sensor with a Model T amplifier. The first thing you need to do is show us the schematic you are using.
