My team is trying to decide what sensor would be the most effective at detecting when balls are "loaded" into our intake. The sensor would be could pretty close to the balls resting place when loaded. We have used touch sensors such as limit switches in other spots on our intake but due to clearance issues and weird angles sensors that do not need to make contact seem like the best option for us at this point. The overall goal is to just detect when a ball is loaded so during auton we know when to stop running our intake and run our linear slip gear puncher. Due to lack of experience with such sensors, we are wondering what sensor would give us the most accurate and consistent values. Any advice or opinions is appreciated, thanks.
