Cable to connect LIDAR sensor nearly 85 ft. from Arduino UNO?

Projects General Guidance
1

Hello, Arduino experts. This is my first project.

I'm trying to automatically control the boom height of my 90' field sprayer using LIDAR sensors connected to an Arduino UNO. I have a prototype working with the short cable that comes wiith the LIDAR sensor, but now I want to try to communicate with the sensor nearly 85' away. I'm not sure what cable I need for such a long distance.

Here's a link to the sensor:

Specs indicate:
Power: 5VDC, <200ma
Rep rate: 1-500Hz
Interface: UART/CAN

Here's a link to a sketch that I used to interface Arduino with the LIDAR sensor:

Thanks in advance for your advice,

CAN bus signals can be used over that distance, but you will need the appropriate interface and cabling, or you could use the UART and RS422/RS485 interfaces.

Thanks for your reply. Can you please elaborate on what is needed?

Google "arduino can bus interface" or "arduino rs485 interface" to learn about the hardware and cabling involved.

Thanks jremington. I'll research those protocols.

Would a 23 AWG CAT 7 ethernet cable work?

Probably... try it out. Many variables.

You may also consider wireless for such links, it's pretty long for a cable. Wireless will be cheaper.

Hi,
How have you got your prototype working now?
Do you have canbus connected?

Thanks.. Tom.... :slight_smile:
