How's the progress with connecting the MLX90620 to arduino? I'm thinking of getting one too. BTW. where did you buy the sensor?

Thanks, I've look at the SoftwareSerial but I'm not sure If I can declare multiple SoftwareSerial ports. Even If I can how do I simultaneously receive from more than one.

I've a need to receive several (2 or 3 ) serial streams from RS232 devices and then send it out the hardware TX pins. Does anyone have any idea how to do it? There's definitely a need for receive buffering, as data can be coming simultaneously from all the ports.
