expected simple serial printing of dh11 sensor data.


Solution

  • This line: Brownout detector was triggered means that input voltage of the ESP32 board dropped below acceptable levels. It indicates that whatever you're supplying the power to it (USB port?) is not capable of outputting as much current as the board requires. Try a USB hub with external power supply, or simply a differet USB port.
