Electronic sensors are in smart devices all around you, such as your cell phone or video game controller. Sensors create the critical link between the physical world and computers by allowing computers to detect changes in color, light, magnetism, moisture, and more!  In order to build automated devices, it’s important to understand how sensors work and how to interpret a sensor's output. This kit lets you imagine, build, and explore a variety of “sensing” devices – the perfect introduction to the world of electronic sensors. 

To get you started on your exploration of electronic sensors, Science Buddies scientists have created 11 projects that utilize the three core sensors included in this kit. With each project, you will learn to build a circuit for your sensor, measure the results, and put your sensor to work in an experiment. We’ve used quality electronic components that will stand up to repeated use, so you can choose to build and test all of the different sensors we’ve come up with, and even go on to invent your own real world applications! 

Instructions for this kit are available online. See below for links to the instructions and more.

You will also need from home:

Depending on the sensor you choose to build, you will need some additional supplies. Please consult the instructions for each project for a complete list of additional materials.


Instructions are NOT included with the kit, but are available online from Science Buddies.
