XGZP6847A

/*
The XGZP6847A is a pressure sensor that can also be used in an analog configuration. Here's an example code in Arduino that reads the pressure from the analog output of the sensor:

Note: This code assumes that the XGZP6847A pressure sensor is connected to pin A0 of the Arduino board. If you're using a different pin, you'll need to modify the SENSOR_PIN definition accordingly. Also, note that the voltage output of the sensor is proportional to the absolute pressure, so you'll need to calibrate the sensor using a known pressure source to obtain accurate readings. Finally, note that the pressure readings are in Pascals (Pa), which is the SI unit for pressure.

const int SENSOR_PIN = A0;  // the pin connected to the sensor
float voltage;  // the voltage reading from the sensor
float pressure;  // the pressure calculated from the voltage

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

  pinMode(SENSOR_PIN, INPUT);
}

void loop() {
  // read the voltage from the sensor
  voltage = analogRead(SENSOR_PIN) * (5.0 / 1023.0);

  // calculate the pressure in Pascals (Pa)
  pressure = (voltage - 0.5) * 100000.0 / 4.0;

  // print the pressure
  Serial.print("Pressure: ");
  Serial.print(pressure);
  Serial.println(" Pa");

  // delay before reading from the sensor again
  delay(1000);
