Check Atmosphere Pressure Using Arduino Mega 2560

Introduction

• In this article, I will explain about checking the atmospheric pressure by using Arduino Mega 2560.
• It can correctly give the range of pressure in the serial monitor.

Parts Of List

• Arduino mega2560
• MPX4115A
• Dual power supply
• LM741
• Bread Board
• potentiometer

MPx4115A

• It can correctly give the air pressure in the atmosphere.
• It can be a barometer application.

LM741 Operation Amplifier

• Very common type of OP-AMP, It provides overload production on the input and output
• It can be easy to use.

Programming

void setup()
{
   serial. begin(9600);
}
void loop()
{
   int sensorvalue = analogread(A0);
   float voltage = sensorvalue * (5.0 / 1023.0);
   serial.println(KPa)

Explanation

• In this article, I explained about checking the atmosphere temperature in the arduinomega2560
• It can be connected to the digital meter and displayed in the serial monitor.
