Futurlec Ultrasonic Sensor Note

Part number US1440, these sensors are not dual use, which means the transmitter and receiver is not exchangeable. They also look identical from the outside, so if you build my arduino ultrasound ranger with these (as I did) and find you can't see echoes, try swapping your transmitter and receiver around! It cost me no small amount of headach this morning.



Cheers,

Steve
