TPH V2

Required items

  • SODAQ SARA SFF
  • SODAQ SARA SFF BASEBOARD
  • TPH

I2C

Connect the TPH sensor to one of the two I2C connectors.

Libraries

Install the following libraries from the Arduino library manager:

  • Adafruit Unified Sensor
  • Adafruit BME280 Library

Arduino Code

#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>

#define SEALEVELPRESSURE_HPA (1013.25)

Adafruit_BME280 bme; // I2C

void setup() {
  SerialUSB.begin(9600);
  SerialUSB.println(F("BME280 test"));

  if (!bme.begin()) {
    SerialUSB.println("Could not find a valid BME280 sensor, check wiring!");
    while (1);
  }
}

void loop() {
  SerialUSB.print("Temperature = ");
  SerialUSB.print(bme.readTemperature());
  SerialUSB.println(" *C");

  SerialUSB.print("Pressure = ");

  SerialUSB.print(bme.readPressure() / 100.0F);
  SerialUSB.println(" hPa");

  SerialUSB.print("Approx. Altitude = ");
  SerialUSB.print(bme.readAltitude(SEALEVELPRESSURE_HPA));
  SerialUSB.println(" m");

  SerialUSB.print("Humidity = ");
  SerialUSB.print(bme.readHumidity());
  SerialUSB.println(" %");

  SerialUSB.println();
  delay(2000);
