5V Photosensitive Resistance Relay Module

Module properties:

The use of photosensitive resistance induced light intensity, comes with a relay, direct control of the load

Adjusting the sensitivity of the potentiometer, by adjusting the potentiometer, set the starting relay threshold. When it is dark on the threshold, module and relay, bright on the threshold, the relay is turned off.

Working voltage 5V/12V

Output form: directly connected to the 220V 10A AC or 10A DC30V load

With 4 fixed bolt holes, easy to install

Small size: 5cm x 2.6cm

PCB 7, the use of a wide voltage LM393 comparator

Module instructions:

The photosensitive resistance module is the most sensitive to ambient light and is generally used to detect the brightness of the surrounding light.

Module in the light more than setting a threshold, a relay, a public end and often start connected, when the outdoor ambient light is less than a preset threshold, disconnect relay, public ends with the normally closed terminal are connected; < br > 3, the public side, normally open, normally closed three ports is equivalent to a double control switch, relay coil power, the public and often begins to conduct, without electricity, the common and often closed end conduction;

Electrical parameters:

Supply voltage: 5V DC/12V DC

Current: more than 100mA

Load: 10A 250V AC or 10A 30V DC
