I'm thinking about building a arduino project that records temp, humidity and pressure onto an SD card. I've done some research and I've decided to use the: SHT15 humidity and temperature sensor from sparkfun (almost I2C) SCP1000 Pressure sensor also from sparkfun (SPI interface) Adafruit Data logging shield for Arduino - v1.0 w/ realtime clock
However, I'm worried that this will be too many serial connections for the Arduino to handle. So I'm wondering if this will work connected to an Arduino Uno (or Duemilenova). If it will work, and I decide I want to add more sensors, how many can I have without overloading the arduino?
Thanks! Also if you have any tips on how I would go about programing this, they would be greatly appreciated. ;)
