Can I install a motion sensor to an existing light?
A remote-style motion detector is a better choice. You can connect it to any type of decorative fixture—even existing ones—and mount it discreetly off to the side. The toughest part of this project may be running the wires that connect the sensor to the light fixtures.

How do you wire a motion sensor to an existing light?
Run the wires into the fixture and screw the motion detector into your light fixture. Connect the hot wire from the house to the motion detector black, the red wire to the hot wire (black in the US) of the light, and tie the neutral wires together. Adjust the sensitivity as needed, button it all up, and call it done.
How do you wire a motion sensor?
What is the red wire for on a motion detector light?
The black wire connects to the black (hot) wire coming into the box. The red wire is switched via the motion sensor (and light sensor) and connects to the black wire that goes to the light fixture.
How do you connect a sensor?
To connect an NPN sensor to a Yocto-Knob, you need:
- To connect ground (-) of the external power supply and the sensor blue wire on the module ground.
- To connect the (+) of the external power supply and the sensor brown wire together.
- To connect the black wire on the channel of your choice.
How NPN sensor is used as PNP?
As they are normally referred, PNP and NPN sensors are both supplied with positive and negative power leads, then produce a signal to indicate an “on” state. PNP sensors produce a positive output to your industrial controls input, while NPN sensors produce a negative signal during an “on” state.
What is the output of NPN sensor?
An NPN output is commonly called a “sinking” output. When the sensor senses an object it will connect the output to the negative supply. A PNP output is commonly called a “sourcing” output. When it senses an object it will connect the output to the positive supply.
How sensors are connected to PLC?
Because NPN sensors are “sinking”, they require a “sourcing” type PLC input card. A PNP sensor is referred to as a “sourcing” switch. This means that the “load”, which is the PLC input, is wired as shown in the diagram below. Notice that the blue “common” wire is connected to the PLC module’s common terminal.
