Sensor Resources

Unfortunately, sensors tend to be a bit more expensive in England than other places, but they are at least quite easy to get.
One very comprehensive website is: Active Robots
It is the easiest to utilize when you are trying out new sensors as you can get them quite quickly.

The website doesn't link to specific products, but i can give you the page/model numbers.


Here are a few to get you started, but if you are looking for something in particular, just post it.

Distance Sensors: gives the distance to an object within a set range.
