How to connect
Buy a USB->I2C adapter based on the CP2112 chip, for example
CP2112 debug board
You should choose a sensor chip with a +3.3V supply.
If you have a 5 volt chip, connect the power wire directly to +5v USB.
Connect your infrared sensor chip MLX90614 to the adapter with 4 wires
according to the datasheet diagram:
MLX90614 doc page
There are 4 wires with the same name connected
How to use
Connect the USB cable and open the TSNS.exe application
If you have done everything correctly and the chip works,
the message "Sensor detected OK" will appear.
Then press the "Loop Read" button to start a loop reading.
We are give a free demo version of the program without the ability to
change the 'Emissivity' parameter and data save.
If you need the full version, you can easily buy it by PayPal (10$).
parameter is a modifying factor
used in single color thermometry to achieve a correct temperature reading.
Emissivity, or radiating efficiency, of most materials is function of surface
condition, temperature and wavelength of measurement.
In the following table, values for the total emissivity of various surfaces,
as well as spectral emissivity at a given temperature, have been tabulated.
The user may find that for the application a different emissivity setting
is required than the one tabulated. This table, however, will provide the
best initial setting. A more refined value should be determined experimentally.
