The board can adjust the sensitivity of light through a potentiometer, comes with a relay, and can be used as various brightness detection control switches. It can be used in devices such as street lights, which automatically turn on at night, turn off during the day, and other devices that require automation.</span></span><br /> <br /> <span style="font-size:22px"><span style="font-family:Arial, Helvetica, sans-serif"><strong>Board parameters:</strong></span></span> <span style="font-size:18px"><span style="font-family:Arial, Helvetica, sans-serif"><br /> 1. The module is powered by 12V and has anti reverse connection function. Reverse connection of power supply will not damage the module;<br /> 2. Load capacity of normally open interface: AC 0V -125V/20A, DC 0V -14V/20A; The module output terminal has three ports: common terminal (COM), normally open (CK), and normally closed (CB). The three ports are equivalent to a dual control switch. When the relay coil is powered, the common terminal is conductive to the normally open terminal, and when there is no power, the common terminal is conductive to the normally closed terminal; The COM end is generally connected to the negative pole of the power supply through the load, and is often connected to the positive pole of the power supply;</span></span></div> <p style="margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;display:block;width:100%"></p> </div></div>
