Hello to all.
Im using a ADXL203 accelerometer to measure tilt and accleration and a 10-bit ADC to ditize the o/p.
The o/p of sensor varies from 0.05V to 4.8V. I need to measure a change of 0.099mV.
The smallest measurable voltage using ADC comes to be (4.8-0.05)/1024=4.6mV (Plz correct me if im wrong on this).
Can anyone plz suggest on how to proceed??
I dont know if there r sensors with a better sensitivity than this one.
Some sort of diferential amplifier maybe required, but Im not sure on how to exactly go abt this one.
Thnx.
