5. இயக்க வழிமுறைகள்

5.1. தரவு கையகப்படுத்தல்

Once the module is correctly connected and the software environment is set up, you can begin acquiring thermal data. The MLX90640 sensor provides a 32×24 array of temperature readings, which can be processed to generate a thermal image.

• I2C தொடர்பு: The module communicates via I2C. Ensure your microcontroller's I2C bus is configured correctly and operating at the desired speed (up to 1MHz for fast mode).
• பிரேம் வீதம்: The sensor can provide data at various refresh rates. The Noise Equivalent Temperature Difference (NETD) of 0.1K RMS is specified at a 1Hz refresh rate. Higher refresh rates may affect NETD.
• அளவுத்திருத்த தரவு: The MLX90640 sensor requires internal calibration data to be read and applied for accurate temperature measurements. This is typically handled by the provided software libraries.

5.2. Thermal Imaging Example

The module can be used to visualize temperature distributions, as shown in the example below with a Raspberry Pi.
