I2C protocol is easy to implement, I recommend you also the widely-used LM75 http://www.esp8266-projects.com/2015/03/pcf8563-real-time-clock-i2c-driver.html

If you want more precision you can use MCP9808 http://www.esp8266-projects.com/2015/02/part3-esp8266-cheap-and-dirty-basic.html

- Mon Apr 13, 2015 7:50 am #14357 Thank you both, this is very helpful. I did not know about the BMP180. Temp and altitude are exactly what I want! I just ordered one. I ordered two esp8266-03 last week. Should I be able to get multiple inputs from the 03, or do I need to order something like the esp-7 or esp-12?

Thanks!

esp03 has gpio12,13,14,0,2 so you can use multiple inputs. esp07 and esp12 has extra 2 gpio(4-5).
