Sensor for magnus cart

Other Hardware Sensors
1

I need a proximity sensor for my Magnus cart. My Magnus cart is a small cart from styrofoam with rubber wheels using a cylinder on top of the cart to move it. The cylinder on top will spin very fast 1400 rpm and with high wind speeds the cart will be moving at 0.5 m/s.

I need a proximity sensor that detects a wall when the cart is moving so the sensor can turn off the motor which will make the cart slow down and come to a stop. The cart will move on a track that’s 2 meters long.

I need another sensor other than an ultrasonic sensor. I’ve used it and now I need another different sensor to write a report on how to improve the cart.

What is the minimum distance that must be detected?

3

85 cm maximum. Minimum probably 80 cm.

You may use HC-SR04 to detect this distance.

I misread the low limit of 5m. This is not a choice.

For a static threshold, not distance readings:

I’ve already used the ultrasonic sensor for my project. I want a different sensor so I can write about improving my cart with a new sensor in my report.
