PULSES

Pulses is used to control output power of the sensor. Each burst from the
sensor contains a number of pulses. More pulses equate to more power and
fewer pulses to less power. Caution: More power may not always be best as
more pulses can create more echoes and may result in false readings.

To read the pulses in a sensor, use the command structure:
