Here i am again...
I drew the scheme.My calculation and datasheet proofed the output of X_FILT and Y_FIL will be the 300mV/g...My purpose is to measure the tilt..If i tilt the sensor 90 degrees,the change is 300mv...Voltage VCC is 5V...
The 0g offset 5V/2 = 2.5V +/-300mV... 300mV when i tilt the sensor 90degree.It's maximum in my project.
What does the supply voltage in OP amp?Only comparation right?
What if i need the Amplification about 5 -> so 2.5V +/-1,5V?
Would be that enough?Are there some calculation of ADC at atmega8?
I want to get a til 1 degree at least..
Which Op amp do you suggest?What else should i consider next?
got a lot of questions i know
