![]() Mine, however, is 0.3 meter more accurate. The adafruit formula still says I am -22 meters. Serial.println(bme.readAltitude(SEALEVELPRESSURE_HPA)) It also sends notifications of pressure chang es and shows - among other things - local and sea level pressures. ![]() It can be adjusted (unusual) to show the atmospheric pressure accurately and is the only app I have used which also - accurately - shows my altitude. P0 is the formula for working out the current sea level pressure using a known height (in this case 44 as that is my current altitude). MEMBERSHIP FAQS Does my membership have blackout dates Are special jump events included in my membership Can I use my membership at other Altitude. It has made my original formula even more accurate. Serial.print("Adafruit Formula: I just tried your idea. Serial.println("Could not find a valid BME680 sensor, check wiring!") The formula I suggested always returns 43.54 meters, which rounded up is 44 you mind testing the following code and telling me what Serial monitor returns? #include And using the average sea pressure of 1013.25 hPa gives my altitude as -22 meters. center: altitude profile showing your current position bottom: remaining ascent or descent (tap screen to change views). ![]() I don't want to edit the code every day so that I can get a accurate altimeter reading. ![]() That is the exact line that is giving me so much trouble. ![]()
