Arduino SMS Alarm
An Arduino based burglar alarm that sends an SMS when motion is detected. It will send an SMS to you every 30 minutes while motion is detected (configurable).
Requirements
- Python
- Python library pyserial installed
- Python library requests installed
- A TelAPI account
- An Arduino
- A Parallax PIR sensor
- Some female-female jumper wires
- Some break-away headers (to convert female to male)
Set up
Wire it up!
- Attach + on the PIR sensor to 5v on the Arduino
- Attach - on the PIR sensor to GND on the Arduino
- Attach OUT on the PIR sensor to DIGITAL 2 on the Arduino
Upload the sketch
- Plug your Arduino into your computer
- Open the
arduino_pir/arduino_pit.ino
sketch with the Arduino IDE - Select your serial port (Tools>Serial Port) and click Upload
Your arduino LED will now be blnking. This means the PIR sensor is calibrating.
Setup the server
- Open server.py with a text editor
- Change the value of
SERIAL_PORT
to the serial port you set in the Arduino IDE. For Windows it might look like COM2, for Posix systems, it might look like /dev/tty.usbserial-AH00PP05 - Change the value of
SMS_FROM
to the number in your TelAPI account numbers (You can set this to another number, such as your own phone and it will cost a little extra. This is what I do.) - Change the value
SMS_TO
to your cell phone - Change the value of
TELAPI_ACCOUNT_SID
to yourAccount SID
as found at your TelAPI dashboard - Change the value of
TELAPI_TOKEN
to yourAccount Token
as found at your TelAPI dashboard
Run it!
- Open up your terminal and run
python server.py
(assuming the terminal is CD'd to the directory where server.py is) - The Arduino will blink it's LED for 60 seconds. Get out of the sensor's sight while it calibrates.
Now, whevever motion is detected in the infra-red spectrum (think body heat), server.py
will send you an SMS up to once every 30 minutes.
Put it in a case (Optional)
- Get some plastic case, like one from a hummus & pretzel snack
- Cut a hole in the top for the sensor to be exposed (like R2D2 in an X-Wing)
- Cut a hole for the USB cable to stick out
- Tape or screw the sensor to the top
- Finit!
