Hello.
I'm trying to do a project with a infrared phototransistor to detect a flame of a candle, not a big flame but almost every IR phototransistor's peak sensivity wavelenght is 880nm-940nm and I wanted to know if a small falme emits this wavelenght or more.

Thanks

If the flame is luminous, then there will be emission in the visible region, too. You might experiment with the phototranistor to see what emisstivity there is in the 880 - 940 nm range.
