Hi I have the following problem, I am using the MAX30100 sensors and the MLX90614 sensor in the LORA 32v2 WIFI module, using the integrated display.
For the MLX90614 temperature sensor is correctly observed on the display, but in the MAX30100 sensor only data of “0.00” is observed as if the sensor is not working.
I tested the MAX30100 sensor individually and it works correctly. Could someone please help me where I am going wrong. I am using the following code:
