Hello TI Family,

what's the minimum distance that can be measured (and is measured practically) with PGA450Q1EVM-S sensor?

Hello Taimur,

Please see the thread and app note below regarding range. The minimum distance is a factor of the transducer configuration(mono static or bi static), transmission medium, and acoustic impedance. I would also recommend the newer PGA460.
