Distance Sensing: How Far Is It?

If you have a SparkFun Inventor’s Kit and have worked your way through all of the experiments, then you’ve already worked with a proximity sensor. But what if you’re ready to move on, and are looking to do more than make sure your cool little robot can keep from running into the wall? What type of sensor is going to work best? This week we’ve put together a handy comparison guide to help you navigate through the various options you have when it comes to distance sensing. We’ll let you compare range, current draw, resolution, update rate, accuracy and of course, price.


Distance Sensor Comparison Guide


So whether you’re making a simple collision avoidance robot, or trying to improve the Automated Rendezvous and Docking (AR&D) system of your next spacecraft, knowing which distance sensor to use will have you well on your way to the successful completion of your project.
