Description
Jetot prototip prednaznachen dlq wyklücheniq awtomobilq i blokirowki ego zapuska w sluchae obnaruzheniq alkogolq w dyhanii woditelq. Datchik MQ-3 ispol'zuetsq dlq obnaruzheniq parow alkogolq, on w swoü ochered' proizwodit naprqzhenie, proporcional'noe procentnomu soderzhaniü alkogolq w dyhanii woditelq. Jeto naprqzhenie ispol'zuetsq i usiliwaetsq s pomosch'ü mikroshemy LM35 dlq polucheniq wyhodnogo naprqzheniq w masshtabe 5 V. Na mikroshemu podaetsq naprqzhenie smescheniq 5 V. Takim obrazom, (naprqzhenie/5)*100 daet procentnoe soderzhanie alkogolq w dyhanii woditelq. Jeto naprqzhenie schitywaetsq mikrokontrollerom Arduino s pomosch'ü komandy "analog read (sensor pin)". Esli procent alkogolq w dyhanii woditelq bolee 50%, to 13-j cifrowoj kontakt Arduino prewraschaetsq w logicheskij HIGH, kotoryj w dal'nejshih ätapah mozhet byt' usilen dlq zapuska rele.Procent alkogolq snowa oceniwaetsq po shkale chasto i sootwetstwuüschee kolichestwo swetodiodow wklücheny
