SENSITIVITY
Sensitivity controls the gain of the receive circuit. High values will amplify the
return pulse enabling the sensor to detect weak signals. Caution: High sensitiv-
ity setting increases the chance for the sensor to detect unwanted objects, which
can decrease the reliability of the output.
To read the Sensitivity in a sensor, use the command structure:
Send
Receive
AAh
Start Byte
