This product fully fit the description. I have tested already and the possibility of sensitivity is great solution, because each room need specific sensitivity. On the highest sensitivity is reaction almost immediate for a water steam as well. This sensor is each aprox. 45 sec. flashing by green light and in dark room is the light relatively intensive.
