Optical smoke sensors are used for detecting visible smoke that appears during the majority of fires. It allows to detect smoke in its initial stage, where the material has just started to burn, which usually comes long before the outburst of open flame and the noticeable increase in temperature. The sensors feature resistance to wind, pressure changes and water vapour condensation. They have large sensitivity to visible smoke.
