Hello!
I want to make a circuit for a ME3 - ETO Sensor that I will connect with a microntroller. I read the sensor's datasheet but I don't know if I will be using proper parts.
Can I use the famous IC741 opamp? The one labeled V- , is that V+? What would be a the best value for Vref? (my microcontroller has 5V logic levels) And the capacitor 0u1, I can't understand what it means.
The sensor is a bit costly so I'm afraid to do some trial and error.
TIA for the advice!
