Ultrasonic
Distance Sensor
The Robotica
Ultrasonic Distance Sensor measures the distance or presence
of a target object by sending a sound wave above the range
of hearing at the object and then measuring the time it takes
for the sound echo to return. By knowing the speed of sound,
the sensor can determine the distance of the object from the
transducer element.

The Ultrasonic
Distance Sensor is available in two different output type
|
|
| |
|
|
|
Ultrasonic
Sensor with Analogue Voltage Output
The sensor gives a voltage output proportional to the distance after
the distance (time) is measured. The sensor's scaling is fixed, where
0 VDC represents a target at 152.4 mm and 10 VDC a target at 1524
mm, with a proportional voltage change in between those two endpoints. |

|
Ultrasonic
Sensor with RS232 Digital Output
After the distance (time) is measured, the sensor transmits the distance
as binary data on the RS232 output. Each count of the binary data
represents a distance of 0.34381 mm at nominal speed of sound. The
sensor provides data up to a maximum range of 3048 mm. |
