Individually these sensor boards would cost over $70, here you get them all in one!
Each sensor can be separated from the rest by a simple snap, allowing for the sensors to be used across the robot.

There are four different types of hall effect sensors that all react a little differently, one latch, one uni-polar switch, one omni-polar switch, and one analog.
And there are two light sensors, one is comparative to make the output a digital signal and one that is an analog output. See the files in the Documentation tab to learn more!

With the 0.5 in. hole spacing, these sensors easily mount to our perforated polycarbonate.
