XGZP6847 Analog Pressure Sensor Module -5kPa to 5kPa

/*
The XGZP6847 is an analog pressure sensor that can measure pressure in the range of -5kPa to 5kPa. You can use an Arduino to read the output voltage from the sensor and convert it to pressure. Here's a simple example:

In this example code, we connect the output of the XGZP6847 pressure sensor to an analog pin (A0) on the Arduino. The Vsupply, Voffset, and sensitivity variables store the sensor's parameters according to the datasheet.

The loop function reads the raw ADC value from the pressure sensor using analogRead and converts it to a voltage value. The pressure is then calculated based on the output voltage and the sensor's parameters. The pressure value in kPa is printed to the serial monitor.

Note: This example assumes you have already connected the XGZP6847 pressure sensor to your Arduino according to the manufacturer's recommendations. Be sure to consult the sensor's datasheet for proper wiring and usage instructions.

const int pressurePin = A0;  // Analog input pin connected to the pressure sensor output

// Pressure sensor parameters (refer to the sensor's datasheet)
const float Vsupply = 5.0;   // Supply voltage to the sensor
const float Voffset = Vsupply / 2;  // Offset voltage at 0 kPa
const float sensitivity = Vsupply / 20; // 20 mV/kPa for the -5 kPa to 5 kPa range

void setup() {
  Serial.begin(9600);
}

void loop() {
  int rawValue = analogRead(pressurePin);
  float voltage = (rawValue / 1023.0) * Vsupply;

  // Calculate pressure based on the output voltage
  float pressure = (voltage - Voffset) / sensitivity; // Pressure in kPa

  Serial.print("Pressure: ");
  Serial.print(pressure);
  Serial.println(" kPa");
