This is an Arduino library for the MLX90614 temperature sensor This library was written to enable remote sensing of the temperature of the rotors of outrunner style brushless DC motors used in remotely piloted aircraft, for the purpose of real time data logging and air to ground telemetry. These sensors use the SMB bus protocol to communicate. This is similar though not identical to the I2C bus. There is enough similarity to enable the Arduino standard Wire library to communicate with the device, however not all features can be implemented, for example it is not possible to read the flags register with standard Wire functions. 2 pins are required to interface the device to an Arduino - the SDA and SCL lines.
