Gravity: DC Fan Module

Create a small automated fan with the Gravity DC Fan module

Here is a handy little tool for exploring technologies/STEM. A small continuous motor and its propeller capable of creating a small fan capable of displacing air.

This 15000 RPM motor (tours/minute) once equipped with its propeller can be used as an automated mini-fan or for the creation of an automated didactic mini-greenhouse. For more ambitious projects, it can be used to create the base of a ventilation system for a low energy didactic house/model.

This small module uses a digital output from the microcontroller to activate the motor. A transistor is used on the module to supply the power necessary for the operation of the motor when the microcontroller (eg Arduino) gives the start-up order.

Gravity connectic facilitate connection to the Gravity IO Shield for Arduino. The Gravity connectic can also be used with breadboard or perfboard thanks to its 2.54mm impaction.

For each order, you will receive a module with the motor, the propeller and a digital cable.
