This active piezo-buzzer module KY-012 will make a beep sound (2.5 Khz) when 3.3V is applied to its input pins. In most cases these sensors will also work with the Raspberry Pi without modification. For example, in lieu of the two-color LED module, you could use a two color LED, 330 Ohm resistors, and a breadboard wire separately to create your own Arduino module. While this makes creating with your Arduino simple, its not entirely necessary. This means they already include things like current-limiting resistors, terminal posts, and potentiometers on-board to help you save time. This list of Arduino sensors and modules are in “module” form-factor. Since modules and sensor grow on the same trees, we’ve made it easy for you to find everything you need for your Arduino projects in one place. Modules could be LCD character displays, LED dots displays, transistor modules, and the like. List of Arduino Sensors and ModulesĪlthough modules are not expressly sensors we’re including them in the list here along with the sensors. In this list of Arduino sensors we’ll explain what each one is used for and some quick links to where you can purchase them. There are many, many sensors and the differences and uses of some of them can be very confusing.
Due to many requests by our user community I’ve put together this handy list of Arduino sensors and modules.
