How to Make a Burglar Alarm Mat

How to Make a Burglar Alarm Mat

If a wire connects the circuit will turn on. If a wire is disconnected the circuit will turn off. Wait, that gave me an idea! So today I’ll show you how to make a burglar alarm mat or an alarm under a mat.

Things you’ll need: Aluminum foil, paper clips, a battery, 3 pieces of wire, 2 straws, tape, and a speaker with sound (I used a piezo buzzer).

  1. Connect two pieces of wire on the battery and connect the speaker to one end.
  2. Connect one more wire to the speaker.
  3. Make a chain out of paper clips and connect it with the other wire.
  4. Tape the straws on the ends of the foil and tape the paperclips between them.
  5. Connect the other wire to another piece of foil.
  6. Stack the foils on top on each other and step on it. The speaker will turn on. You could also hide it under a rug or a mat.

A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in “multistranded wire”, which is more correctly termed a wire rope in mechanics, or a cable in electricity.

Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, such as the Slinky toy, are made of special flattened wire.

  3. acflory – Australia – I am the kind of person who always has to know why things are the way they are so my interests range from genetics and biology to politics and what makes people tick. For fun I play online mmorpgs, read, listen to a music, dance when I get the chance and landscape my rather large block. Work is writing. When a story I am working on is going well I'm on cloud nine. On bad days I go out and dig big holes...

    Looking forward to it. 🙂

  4. The components are normal things around the house? Well, I was going to use some science and harder-to-find components. Anyway, thank you so much for commenting and liking this post. Stay with me and some better experiments will come along.

  5. This is a great idea for a burglar alarm, or to let you know someone has entered your shop, and it isn’t expensive to set up. 🙂

    This is fantastic, DAn. I love how most of the components are normal things you’d find around the house. 🙂
