@InteractiveHome, для меня, как инсталлятора, интересны способы объединения этого элемента системы освещения с остальной системой освещения, и далее - с системой управления. Какие существуют возможности на этот счет?
Наверняка это можно использовать. Тут дело в том какие задачи стоят, в выдумке и фантазии исполнителя) Изначально имелось ввиду автономное использование системы автоматики для управления подсветкой и освещения лестницы. Она наиболее актуальна именно в темное время суток (когда остальное освещение выключено и уровень естественного света низок). Для определения факта "наступления темноты" в подобных системах служит датчик освещенности.

Ну, тот страшный датчик стоит 32 евро, если я правильно подсчитал. И кроме подсветки ничего не умеет и работает только со своим контроллером. Меня бы из-за него жаба задавила.
Есть и по 8,5 евро аналоги, и то основная стоимость в арматуре датчика, нужно красивый дизайн, плати .
Никто не видел недорогие диммеры, основная задача которых - просто плавное повышение освещение СД-ленты? На али есть полно недорогих контроллеров регулирования с несколькими программами, но они управляются кнопкой - т. е. меняют режимы после запуска ленты. Нужен просто плавное увеличение света для комфорта (плавное затухание обеспечивается конденсатором БП ).
И то же самое, но наше посконное, Русское За 6 евро Пирон-5 - это извещатель охранный, оптико-электронного типа. Устройство включает в себя микропроцессорное управление и настройку чувствительности, а также сферическую линзу, которая обеспечивает качественное наблюдение за зонами, без помех и искажений. Основное предназначение - это охрана домаили любого технического помещения, где необходимо максимально исключить вероятность проникновения злоумышленника. Охранные системы, которые используют данную модель, получают тревожный сигнал на контрольную панель после того, как происходит размыкание шлейфов на датчике, посредством реле. Имеет высокую степень защиты от различных источников радиопомех и засветок внешнего типа с мощность до 6500 Люксов. Важная особенность - это регулировка чувствительности дискретного типа для животных. Пользователь может самостоятельно настроить уровень чувствительности устройства, выбирая режимы нераспознаваемых объектов от 10 до 40кг. Установку рекомендовано осуществлять в угловых зонах помещений. Поддерживает возможность выбора дальности срабатывания: Режим 10 кг - максимальная дальность 10 м (кошки, декоративные собаки); Режим 20 кг - максимальная дальность 9 м (кошки и небольшие собаки); Режим 40 кг - максимальная дальность 8 м (длинношерстные собаки); Режим 40 кг - максимальная дальность 7 м (любые собаки до 40 кг).
