I2C temperature, humidity and pressure sensors
Fistr:
Hi,
I plan to build my own outside unit for my weather station based on AVR microcontroller and I would like to hear your ideas and suggestions about what sensor(s) should I use. I need to measure temperature, humidity and pressure, as you can see from the subject, and the sensor must communicate via I2C interface. Low power consumption would be also good, but it is not neccessary. Sensors can work on both 5V and 3.3V voltage levels. I was thinking about BME280 on breakout board. What are your ideas and recommendations?
Thanks for your answers. :)

I've been running the old BMP085 for many years and it works (temp and pressure).
I think the BME280 is the way to go unless you want to measure at 30km altitude..
jhpadjustable:
I second the BME280. It's a fine sensor, quite accurate, maybe a little bit spendy if you buy them through proper channels.
Fistr:
Thank you, I'll probably go with the BME280 but if anyone else has other recommendations I'll be happy to hear it.
ANTALIFE:
Working on similar thing, have chosen the BME280 & SGP30
