		<description><![CDATA[To anticipate the dangerous and harmful wind, this wind detector circuit is able to give the early warning system. Wind detector circuit uses an incandescent lamp to detect airflow (wind detection). With the filament exposed to air, a constant current source is used to slightly heat the filament. Because it is heated, the resistance increases. [...]]]></description>
