Sensor that can detect short range obstruction

Hi Community,

I'm planning on a creating a device that would be helpful for blind people to detect short range obstruction from waist above that walking sticks can't. What type of motion sensor would be preferred for this situation? I also plan on connecting it to a raspberry pi device?

I saw a device made by some students for a final year project at Curtin University that used Ultrasonic. The application was suitable as they wanted it to be used as a walking stick but I can a few problems…

Check out Maxbotix sensors - they have a selection of sensors with different beam angles.

But Maxbotix sensor are costly starting from $30. I found MULTICOMP MCUSD16P40B12ROMCUSD16P40B12RO TRANSCEIVER can be used But I donot know what are two pins of MULTICOMP MCUSD16P40B12ROMCUSD16P40B12RO TRANSCEIVER And how to trigger it
I mean how to use MULTICOMP MCUSD16P40B12ROMCUSD16P40B12RO TRANSCEIVER to measure distance?
MULTICOMP MCUSD16P40B12ROMCUSD16P40B12RO TRANSCEIVER costs just$6
