Hi all, A friend of mine recently asked me to make him something which would let him view temperature readings from 4 probes placed in different areas of the car. These readings will then be displayed on a 20x4 ascii LCD. It will also have data logging, to record temperatures every 5, 10min (unsure of exact intervals at this stage).
So, here are the questions:
- I have found a sensor which I think would do the job (http://www.adafruit.com/products/381). How effective would this be connected to an i2c adapter?
- What is the best protocol to use for the LCD?
- What is the most effective method for data recording to an SD card?
