EXCELLENT sensor, easy to use and accurate.

The BMP280 is an excellent barometric pressure sensor. This sensor is very accurate and the readings hardly fluctuate. I've used this and an Arduino microcontroller to measure height, and if you lift the sensor even half a foot, the sensor will accurately register the change in height. The temperature this sensor reads is very accurate - exactly 4 degrees Fahrenheit above the actual temperature :) I've read that the chip heats itself up to allow the sensor to function properly. Maybe that's why

Pros
  • Few competitors
Cons
  • Unreliable

Incorrect description

Be careful with this product. While the name is correct (Adafruit BMP280 I2C or SPI Barometric Pressure and Altitude Sensor), the product image and description is for the BME280 sensor board. The difference between the two is that the BME280 board has a humidity sensor while the BMP280 board does not. Another difference is that the I2C addresses are different, which might explain why some other browsers couldn't get it to work. However, as a BMP280 board it looked well built, was clearly marked

Pros
  • Handsfree
Cons
  • Very expensive

Works perfectly. Not compatible with BMP180.

onboard BMP085 behaved "fun". The 5v to 3.3v level switch came in handy as my flight controller runs on 5v. The BMP180 would not work due to hard coded conflicting i2c addresses. I suspected this chip might not be compatible, but figured I could get it working for the price. The UI was relatively similar and I got it working in a couple of nights. It worked great to calculate relative altitude to within a quarter of a meter (within a reasonable amount of time). I have never checked the accuracy

Pros
  • A lot of positive emotions
Cons
  • No power
