with a fixed response time and high light sensitivity

Eld sensor magnet it is usually driven byA sensor designed to detect open flame or fire quickly and accurately, with a fixed response time and high light sensitivity. It runs on 5V, has a peak wavelength of 940nm. With its high reliability and low voltage operation, you can trust that the Fire Sensor will detect any fire. The sensor is very sensitive to IR light Specifications: Package type: leaded Dimensions: 5mm Leads with stand off Peak wavelength: ? p = 940 nm High reliability Fixed
