This neat little board is GREAT for automatic light sensitive projects that don't require any micro controllers.
A very good idea idea would be to attach a light to the relay side, and leave the LDR in the a place where it will recieve light,
then simply adjust the potentiometer to let the light turn on or off when the Sunsets or Rises. Now you have your very own,
automatic outside light. This principle can be applied to almost any device that you might want to turn on or off in relation to a light source.
Uses a photosensitive resistor inductor to measure intensity of light. With the use of the high quality relay you can directly control the load of an AC or DC device.
Maximum Ratings: AC 0V-250V@10A OR DC 0V-30V@10A;
The sensitivity of the light to trigger the relay can be adjusted with an onboard poteniometer.
Reverse polarity protected
