Recently, I used Arduino along with XBee and the temperature sensor MLX90614 to wirelessly send temperature data to my laptop being read in the COM port. The data seemed to read fine when the set up was in room temperature and not moving. But under other circumstances, it became a problem getting the sampled data.
In hindsight, MLX90614 was probably not the best sensor for this use - a contact sensor could have given me more accurate data, and I could have used XBees with a higher power.
