Thermal Camera: Arduino UNO + MLX90614 IR Thermometer




I  did the following steps:

1) Hardware: Connect the MLX90614 (refer to the datasheet) as follows: Pin 1 on MLX (SCL) connect to ANALOG pin 5 on Arduino Pin 2 on MLX (SDA) connect to ANALOG pin 4 on Arduino Pin 3 on MLX (VDD) connect to 3.3V on Arduino Pin 4 on MLX (VSS) connect to GROUND on ArduinoThermal Camera Arduino UNO  MLX90614 IR Thermometer




Now use “pull ups” on the SCL and SDA lines by connecting a 4.7K ohm resistor from the Pin 3 VDD line to the SCC line and a 4.7K ohm resistor from the Pin 3 VDD line to the SDA line.

2) Connect the RBG LED. Simple wiring diagram for RGB LED: http://wiring.org.co/learning/basics/rgbled.html. For the attached Arduino sketch, hook up is as follows:

Leg 1 = RED pin of the LED to PWM pin 6 Leg 2 = Ground Leg 3 = GREEN pin of the LED to PWM pin 5 Leg 4 = BLUE pin of the LED to PWM pin 3 {***NOT pin 4 as shown in the diagram above!!!!!!!!!}

3) Software: Download MLX90614 IR Thermometer Library here: http://bildr.org/2011/02/mlx90614-arduino/

To make this code work, before you load the code, or even open the Arduino program, we need to place the “I2Cmaster” in your Arduino Library.Thermal Camera Arduino UNO  MLX90614 IR Thermometer SchematicOn your Mac:: In (home directory)/Documents/Arduino/libraries On your PC:: My Documents -> Arduino -> libraries On your Linux box:: (home directory)/sketchbook/libraries

Final Arduino sketch attached.
