Ultraviolet-sensitive flame sensor (for both indoor and outdoor use) SKH047M 1 piece

It instantly detects even the smallest flames. A flame of about 2cm in size can be detected in as little as 0.5 seconds from a distance of about 5m. The technology to separate the ultraviolet rays from sunlight allows it to be used outdoors without compromising performance.
