empowering creative people

Sensors are the eyes and ears of electronics, they monitor external stimuli such as sound, light, pressure, and heat, and convert them into signals for your microcontroller to process.

We've got all kinds of sensors available for your project, so make sure that you pick the correct one for your hardware. If you get stuck, be sure to reach out to us via our forum.

Take a look at some of our sensor tutorials:

Accelerometers

Accelerometers are the basis of all motion control. They allow you to sense both static and dynamic acceleration and are easy to integrate into your project.

Some important factors to take into account when buying an accelerometer for your project:

  • Sensitivity (some have variable options)
  • Resolution
  • Communication method (eg. I2C or SPI)
