Датчик холла управляет транзистором.
При появлении напряжения на датчике(подносим магнит) транзистор должен закрываться, а при отсутствии(убираем магнит) - открываться.
Вопрос в том, есть ли такие транзисторы. Или как это реализовать по другому.
а какой датчик холла?
От ВАЗ 2109.
Это называется усилитель напряжения. Или используем операционный усилитель, в зависимости от решаемых задач. + силовой транзистор, если коммутируем большой ток.
Может подкинете простую схемку? Коммутируемый ток 100ma.
лень рисовать
в базу датчик холла. рассеиваемую мощность сами посчитайте.
