37 Sensors Overview


“37 Sensors” is the common name for a number of kits of small electronic modules. Not all of the kits have 37 modules in them – some have more, some less. Also, although a large number of these modules are what would be considered “sensors”, some are certainly not sensors (things like RGB LEDs and relays).

If you are curious as to how to interface to these common modules, this site has interface information and example code for more than 37 of these modules. If you have questions or more information to share, please leave a comment. If you have created a project using a certain module, it would be nice to hear about that, too!

If you have more information about certain modules, please feel free to Contact us! and share what you know. If you also have test or application code to share, that link is the way to share that. And we would appreciate that a lot!

If you are interested in purchasing the unique devices that are shown on these pages, CircuitGizmos (link: CircuitGizmosOnline) sells many of these devices. Also Tindie has several of the CircuitGizmos devices for sale.

If you have questions about sensor modules like these, consider joining the Facebook group. Join the 37 Sensors FB Group! We'd love to see you there. If you are interested in the CircuitGizmos products, the FB page to join is CircuitGizmos on FB

Sometimes the 37 sensor projects are described as Instructables. This is the Instructable user to follow: Indestructable and YouTube channel and even follow on Instagram.
