I want too hook up 2x humidity sensors to an Arduino and log the data to an SD card. 1 sensor should be in the attic so I would want a wireless connection here. Would it work with the following components?
2x Sensiron Temperature/Humidity Sensor - SHT11 (ID: 246)
2x XBee Module - Series 1 (ID: 128)
1x Adafruit Data logging shield (ID: 243)
I haven't used an XBEE yet but do I understand it correctly that I can just hook up a XBEE to the Arduino and one to the Humidity sensor and then simply read/send values to the humidity sensor (those 2 XBEEs create a wireless serial connection)?
To hook up the second serial humidity sensor I'd probably need a second serial port? (either soft port via library or multiplexer to switch between sensors?)
Also can I assume that I can access the RTC in the logging shield to use it as a timer?
