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 (Waterproof 1-Wire DS18B20 Digital temperature sensor : ID 381 : $9.95 : Adafruit Industries, Unique & fun DIY electronics and kits). 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?
