Maximum Range of an IR Flame Sensor (KY-026 or similar)

Hello everyone,

I am trying to implement an IR Flame Detection Sensor to my project in order to detect fire in a large area. I will have to use many of these sensors, so I need their range in order to determine their exact number.

Has anybody tested them in an open field with a relatively large fire ? (the word relatively refers to the small flame from the lighter I have been using in my indoor tests due to COVID lockdown ).

Any help would be appreciated.

Repeat the tests you have done by doing them in the bright sunlight. That will tell you how well the operate in the open field.
