Dog Couch Protector





Introduction: Dog Couch Protector

Hello everyone! In this instructable, I will show you how to make a device that sets off a small alarm when your dog jumps up onto your couch. My dog is so lazy that she probably wouldn't get up anyway, but for regular dogs, it shouldn't be a problem.

Step 1: Parts and Tools

Here are the parts and tools that you will need to complete this project:



PIR Sensor

Piezo buzzer


Linkit ONE board

Acrylic sheet

Lithium Ion battery (included with board)


Computer with latest version of the arduino IDE and the linkit one drivers

Soldering iron and solder

Glue stick

Desktop printer and paper


Step 2: Wiring

Wire the circuit according to the attached circuit diagram.

Step 3: Code

Download the attached code and press upload.

Step 4: Cut Out Case

Glue the provided template and use a glue stick to glue it to a sheet of acrylic. Now, cut it out on a bandsaw or scroll saw.

Step 5: Glue Case Together

Take the acrylic pieces that you cut out in the previous step and glue them together to form a box.

Step 6: Mount Electronics Into Case

Start by gluing the PIR sensor to the the inside of the enclosure, making sure that the half-dome shaped part is facing upward. Then, glue the Linkit ONE board with a small amount of hot glue.

Step 7: Testing...

To test the device, turn the battery switch on the board so that it is on battery: USB --> BATT. Now, place it on a couch and wait... When a pet jumps onto the couch, it will start beeping and flashing.

    This is great. My girlfriend's cat is not allowed to be on the couch, but it doesn't seem to understand that. This might just do the trick. Thank you.
