Programming XBee to transmit and receive data

Don't forget to show your appreciation with the karma button

I didn't know I could do that. Well your 'karma points' are up now.

Hmmm... temperature sensor, now liquid flow meter... Just out of curiosity, what is the full project? An aquarium monitor? Hot water meter? Thermally triggered water cannon?

Temperature of the exhaust gas from a car. I need to measure the rpm of the wheel as well. So in all, the data I need to capture in real-time are :

  1. Temperature
  2. RPM of the wheel
  3. Flow rate of the exhaust gas

All these should be graphed simultaneously against time.
