The code, working with interrupt need some correction.
You attach detectsMovement function as interrupt handler and declare it:
void detectsMovement() {...}
But correct code must be:
void IRAM_ATTR detectsMovement() {...}
IRAM_ATTR need for place interrupt code to RAM, otherwise code stored in flash

Hi! Thanks for the great tip.
I’ve just tried it myself and read about it, it’s definitely faster and better method.
I’ve updated the online version of the course: https://rntlab.com/esp32-with-pir-motion-sensor-interrupts-and-timers/ (ESP32 with PIR Motion Sensor)
The eBook will have that change too in the next update.
