Non Contact Temperature Measurement using MLX90614         

               

                   IR thermography is the one of the concept ,that is used for monitoring temperature value without attach on the substance .So it is having more advantageous .By using MLX90614,we can monitoring oil, fruits and food temperature also .Here I have attached one of my prototype concept while working on it.

Functional diagram:

       The sensor is having inbuilt DSP FIR filter algorithm.So output of the sensor is very stable and good accuracy .But based on the distance the accuracy will be changed.And then it supports SMBus protocol. SMBus protocol seems to be same as I2C protocol but clock rate varied.

If you know about SMBus, go through the following site

https://en.wikipedia.org/wiki/System_Management_Bus

Step 1: Check it out device address for MLX90614

Device address with write  - 0xB4

Device address with read   - 0xB5

Device address without read and write bit -0x5A

Step 2: Check it out fclk or sclk

Step 3: Voltage rating

Step 4: Write down the driver code as per the following clock and protocol format

Step 5: Write down the application layer

Step 6: Calibration and data conversion code

Step 7: Testing your code

You can get my sample code from my github account.
