MLX90614_Serial_Demo.ino
Serial output example for the MLX90614 Infrared Thermometer
This example reads from the MLX90614 and prints out ambient and object
temperatures every half-second or so. Open the serial monitor and set the
baud rate to 9600.
Hardware Hookup (if you're not using the eval board):
MLX90614 ------------- Arduino
VDD ------------------ 3.3V
VSS ------------------ GND
SDA ------------------ SDA (A4 on older boards)
SCL ------------------ SCL (A5 on older boards)
An LED can be attached to pin 8 to monitor for any read errors.
