Hall Sensors #2

Open freshrick opened 4 years ago

freshrick commented 4 years ago

Do you have any documentation about connecting the Hall Sensors to raspberry pi? I'm tryin to get odometry data for the robot tank.

Thanks a lot.

I think the Hall Sensors output logic 5V and therefore you cannot connect them to the Rasp. Pi, which runs on 3.6 Volts (logic). You might need to use a TTL logic level converter IC in between.

Other than that, you just connect them to GPIO aka digital, and then read the logic levels from the S1 and S2 lines. Make sure to keep in mind the order of these connections. Could you please more specify what you are trying to accomplish:

Cheers David

Hello! And thanks for your reply! I will try it with the GPIO Solution next week. I want to get odometry data to write ROS nodes. I want to combine one of your robots with an ydlidar to make it SLAM. Do you have any Tutorials with arduino to get some odometry data?

This would be very helpful!

Thanks a lot Kristian
