Is there anyway to get or download the current weather temperature from the web to use either in an Arduino sketch or ESP-32 application. Thanks for the help.

ESP32 flame sensor false triggering — need help

I’m using an ESP32 with a flame sensor and buzzer. The problem is that the buzzer turns ON even when there is no flame.

I tried:

\- Adjusting the sensor potentiometer

\- Changing the code

\- Changing the sensor position

But it still triggers without a flame. The ESP32 and buzzer are working properly.

Could this be a wiring issue, inverted HIGH/LOW output, faulty sensor, or something else? How can I test whether the flame sensor itself is working correctly?

I’m a beginner, so any simple troubleshooting steps would be really helpful.
