long range distance sensor

Projects General Guidance

Hello,

i would like to use arduino to receive the distance of ultrasonic distance sensors. In this project the sensor will be ~50 meters away from arduino. Will the signal be strong enough? Or there will be a problem because i am using 50 meters wires?

thanks

50 meters of wires will be a serious problem and is unlikely to work.

You could put an Arduino at the remote site and use a radio link or an RS485 wired connection to communicate the result back to the base.

Use a wireless solution, such as a xbee.
