SENSOR CONFIGURATIONS
As ultrasonic transceivers, the CH101 and ICU-10201 are capable of measuring distances to objects just by themselves. However, a
network of sensors can be used together for additional functionality such as 2D and 3D location identification. The most common
sensor configurations are detailed below.
3.3.1
Pulse-Echo
The Pulse-Echo configuration is the basic configuration for the sensor In Pulse-Echo, a single sensor both transmits and receives its
own ultrasound to perform measurements.
Figure 3. Sensor operating in Pulse-Echo configuration.
In Pulse-Echo, the sensor both transmits and receives its own ultrasound signal.
3.3.2
Pitch-Catch
In Pitch-Catch configuration, one sensor is set as the transmitter, while one or more additional sensors are acting only as receivers. A
common use case of Pitch-Catch is to have one or more sensors on separate devices. This allows for the tracking of the distance,
position, and even orientation between devices depending on how many sensors are used.
