How To Choose The Best Rotary Potentiometer For Your IoT Project

A blog article discussing how to choose rotary potentiometers that will fit in your project. The article includes a comparison between the types of potentiometer and details about the most common applications for this type of sensor.

What is a Rotary Potentiometer?

A rotary potentiometer (or rotary switch) is a type of potentiometer that consists of a round, rotating element that allows you to adjust the voltage or current going through it. They’re used in many different IoT projects, including controlling lights and motors, as well as other electronics.

What to Consider when Buying a Rotary Potentiometer

When choosing a rotary potentiometer, it is important to consider the specific needs of your IoT project. For example, a rotary potentiometer with an adjustable range may be necessary for controlling a motor or turning it on and off an LED. Other factors to consider when selecting a rotary potentiometer include the following:

Range: The range of the rotary potentiometer is essential for controlling the motion or brightness of an object. The greater the range, the more flexibility you’ll have in adjusting settings.

Pitch: The pitch of the pot is how wide the adjustment range is. A higher pitch means a wider adjustment range, while a lower pitch results in narrower adjustments.

Locknut Size and Type: It’s important to choose a locknut size and type that will fit your project needs. For example, if you’re using a rotary potentiometer to control motor speed, you’ll need one with an adjustable nut size.


Choosing the right rotary potentiometer for your IoT project can be quite daunting, but with a little research, you should be able to find the perfect one for your needs.
