Welcome to the SparkFun_BME280_Arduino_Library wiki!

Dew Point can be measured using the August-Roche-Magnus approximation like the following example:

`Serial.print("Dew Point: ");
 Serial.print(243.04*(log(mySensor.readFloatHumidity()/100)+((17.625*mySensor.readTempF())/(243.04+mySensor.readTempF())))/(17.625-log(mySensor.readFloatHumidity()/100)-((17.625*mySensor.readTempF())/(243.04+mySensor.readTempF())))); 
 Serial.println(" F");`
