INTRODUCTION

In this illustration, we will be going to wire the IRF520 MOSFET (Metal Oxide Semiconductor Field-effect Transistor) Module Board a simple breakout board for driving higher loads. MOSFET enables you to control higher voltage projects on the microcontroller. MOSFET is also a kind of a switch that isolates the power from the main Load, when the power loads to the MOSFET it will pass the power from one to another when closed, but if the outer power source is absent your device can still draw power from microcontroller.

In this illustration we will be going to use to MOSFET Module board, we connect the power for the device you want to control to the VIN and GND then connect your control a pump, LED, or other DC device, to V+ and V- up to 24v, and ~5A. You can also power this device from your Arduino to a 5v VCC connection and GND pin.

WORKING

Welcome to this Arduino-based IRF520 MOSFET Sensor Module which mainly consists of a VCC (Power Supply), a ground (GND) pin and a Signal (SIG) Pin. It is being made to process the speed and to control DC motors. Its basic functionality is to be able to control the voltage and current flow between the source and drain.

It works almost as a switch. The working of MOSFET depends upon the MOS capacitor. The MOS capacitor is the main part of MOSFET. The semiconductor surface at the below oxide layer is located between the source and drain terminal. It can be inverted from p-type to n-type by applying positive or negative gate voltages respectively. The Potentiometer used in this particular circuit also has various applications such as LED lights, DC motors, Miniature pumps and Solenoid valves.
