Better than a trick birthday candle
When we built the FirePixel, windy environments were a challenge we needed to address. So each FirePixel has an electronic flame sensing system capable of detecting not only when the flame is on or off, but even when it is about to blow out.
It takes a fairly strong gust of wind to even blow out the FirePixel at all. We accomplish this in the shop with a 90psi blast from an air compressor. And note in this video that as the FirePixel blows out, each time it relights on the first spark, in under 1 second. With subsequent blowouts, the minimum flame size is increased so the flame resists the wind even better. When the wind is reduced, the minimum flame size goes back down to a tiny candle.
