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
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.
