I am using MLX90640 for a project to detect human presence and I followed a tutorial online to test it (Tutorial followed: High Resolution Thermal Camera with Raspberry Pi and MLX90640 — Maker Portal). However, in the “Visualizing the MLX90640 - Real-Time Thermal Camera” and “Real-Time Interpolation of MLX90640” sections, I was only able to get figure output by using 4Hz for the refresh rate rather than 8 or 16 Hz. I read the datasheet for the sensor and it talked about how “Capacitive loading on an I2C can degrade the communication”, so I am thinking about adding a 10uF capacitor to the sensor to helo improve the refresh rate.
Has anyone here had the same issue with a lower refresh rate? If so, how did you solve it? Is adding a 10uF capacitor a reasonable approach?
Any help would be appreciated. Thank you in advance!
