12 VOLT Motion Detector sensor switch PIR 12-12 volt DC w/timer great for LED’s
12-24 volt input 12-24 volt output motion detector switch. PIR ( Passive InfraRed ) Compact design 2 to 8 minute timer (easily adjustable) with a small screw driver you can use 12 or 24 volts input and can use 12 or 24 volt output. Input and output do not need to be the same. Great for use with 12 volt LED’s Marine camping boating house security RV and more Simply hook up a power source( battery or power supply) hook up a lighting option( I use 12 volt LED’s) . You can mount the detector and pull the green plug out, conveniently attach the wire and simply plug it back in. I have several of these in use in my house and office I love them. I have one in my personal clothes closet, My closet was dark and I could not see well at all so I bought the same PIR dect. and installed one in my closet, one on my kitchen steps leading to the basement, one in a closet I use in my office for storage. I hooked up 12 volt 10 amp hour batteries, I took the same LED strips I sell ( cool white) cut them into 1 meter pieces( 60 led’s per /meter) Now I can actually see the difference between blue and black clothes, I can see the canned goods on the shelves leading to the basement and can see in my storage closet easily. How many times can I say I love them. All my timer settings are on 1 minute. Now the only drawback was the batteries would draw down in about 3-4 days because the motion detector is constantly on, So I replaced the batteries with the same 2 amp power supply I sell.
