More in the line of robotics observing their environment, I'm trying to implement a proximity sensor that can sense objects in front of it to a least up to $-30^ \circ \space$ to $\space+30^ \circ $ of it's direction of propagation.
There are only two ways I can think of
- Multiple Infrareds. Con: more spacious
- Fast-Motor. Con: expensive in money and time-complexity wise
I'm currently using a Proximity Sensor with up to 10ft distance capability
