And the Sensor will now send pulses to - and listen to echoes from - interruptions of the Beam up
to 3 m away.
Now, try walking towards the Sensor from, say, 4m away (in the direction which the
Sensor is pointing) - listening for the exact place where your body meets the furthest end
of the Beam from the Sensor and starts to generate sounds.
Next, walk in and out of the 3m long Beam, listening to what happens and trying to judge
when you’re interrupting the Beam and when you’re outside it.
