Привет всем !
Хочу сделать ночную подсветку для аквариума, так чтобы днём включался один тип LED, а в тёмное время суток соответственно другой.
Скажите пожалуйста, будет ли работать светодиодная подсветка если впаять такой выключатель ?
К сожалению подробной схемы я не нашёл, только описание на инглише.
Module features:
1, the use of photosensitive resistance induction light intensities, comes with relay, direct control load
2, power distribution switch adjusting sensitivity, by adjusting the potentiometer, set start relay valve value when this threshold is dark in, snap module relays, light on when this threshold, the relay releases;
3, 12V power input for the relays used, onboard 78L05 voltage regulator transistor, sensor provided comparer, make the product more stable and reliable;
4, the drivers for the on-board optical coupling isolation relay, effectively protect the chips, making products more reliable work;
5, with 4 fixing bolt holes for easy installation
6, small Board PCB dimensions: 5cm x 2.6cm
7, use wide LM393 voltage comparator
Electrical parameters:
Supply voltage: 12VDC
Current: greater than 100mA
Load 250V AC or DC 30V 10A (below this range of currents can be used)
Или такой:
1, Size: length 30mm * width 10mm * height 13mm
2, Main chip: LM393 Photosensitive sensor probes
3, the operating voltage: DC 3-5V
4, Feature:
1, with signal output instructions;
2, module with hole, Convenience for installation;
3, output valid signals are low-level, led light;
4, adjustable sensitivity (fine tuning);
5, for the required constant temperature test;
6, the output signal can directly connect monolithic integrated circuit IO Port; Application: automatic curtain, teaching experiment, light detection and so on
