Too many lost sheeps in this world.

Here is the ultimate invention to keep your sheep in sight.

What's RF Sheep Tracker ?

It's a collar equipped to transmit a continuous signal so, when it's out of range, a buzzer alert sound is played on the receiver device.

But the collar can do more:

  1. sheep moving alert - when is detected a motion of the sheep, a fast buzzer sound is played on receiver device (when transmitter and receiver are in range)
  2. rainbow light during "night mode" - a button activate night mode on the collar. A RGB led color cycle glows, giving a note of colour to your white sheep
  3. moving light during "night mode" - a flashing white light on motion detection on the collar so you can visually track your sheep during the motion

no sheeps were harmed during the testing of the RF Sheep Collar

Step 1: HOW IT WORKS

Described features are obtained using:

Arduino Nano

RF 433MHz transmitter

Arduino Uno

RF 433MHz receiver

Lilypad RGB led

Accelerometer

An accelerometer read motion status and send the information to Arduino Nano that manage it and, via RF transmitter, send continuously motion status to a receiver device.

If receiver device get signal means that the collar is "in range" and it shows only a blinking led . When receiver doesn't get incoming signal, an incremental buzzer alert sound can be listened.

When transmitter and receiver are "in range", if the information sent by the collar is "motion", a short buzzer sound can be listened on receiver device.

A button pressing on collar activates the "night mode". This means that the collar RGB Led glows and show, successively, sequential RGB colors and, when detect motion, a white blinking led alert glows instead of colors.

As you can see the concept is similar to Disco Dog . Differences are:
Disco Dog communicate via Bluetooth, RF Sheep Tracker via 433Mhz. This means more communication range for open spaces. The prototype made allow communication between transmitter and receiver around MAX 40 meters at open air . The range can be also reduced .

<p>hey, this is an excellent project! Though im not going to use it to track sheep but rather to make a range finding system, i was wondering how you can control the range of the rf module as they have a set range depending on your environment as far as the rf waves can travel. Please let me know how you did that. Thank you</p>
I'm glad you like it.<br>RF modules range depends on multiple factors and cannot be controlled upstream. Buildings, interferencies, receiver shielding, makes a difference. My statement &quot;The range can be also reduced&quot; comes from empirical tests. I have observed that increasing transmission speed the range decreases. In my case, changing Wirtual Wire speed setup from 1000 to 2000 range decreases approx. from 40 to 4 mt., in the open air. <br>First time i used these RF modules, i was not satisfied about range covered. Telecontrolli enginner told me that my receiver PCB needed of more shielding, so i soldered a metal plate connected to GND on receiver module. He said also that, with a good shielding, these modules can communicate 100 meters away.
<p>Hey this is cool! </p><p>I thought you might like to know by coincidence, I just worked on a project with the BBC to try to track stolen sheep...we cam at things in a different way, but it's really interesting to see your approach and final design.

thanks for your concern.<br>I've watched tv programme and just never realized stolen sheeps could be so prevalent. <br>...the thieves are very fast to steal a flock of sheeps!
