Step 2: Add Necessary Libraries to the Arduino IDE I know some of you will not need anymore info than this and the sketch attached below but I will go into some more detail for anyone who would like a little further assistance. I2C 16X2 LCD Module VCC to 5V, GND to ground, SCL SDA pins to SCL SDA of the Arduino (pin A5 is SCL, pin A4 is SDA)ĭS3231 RTC Module VCC to 5V, GND to ground, SCL SDA pins to SCL SDA of the Arduino (there is 2nd set located above the GND and AREF pins of most Arduino's) LED between pin 8 of the Arduino and to a 220ohm resistor then to earthĤ33 or 315 Mhz receiver, VCC to 5V, GND to ground and either one of the 2 data pins to pin2 of the Arduino Piezo between pin 5 of the Arduino and earth Step 1: Wire Up the Ardunio and Modules As Shown in the Imageįile:///home/samba/transfers/frizting.png Wireless Alarm reed switches, motion sensors and remote key fobs as desired See additional notes at end to ensure you use the correct version of these parts.Ĥ33 or 315 MHz receiver module for ArduinoĭS3231 Real Time Clock module for Arduino The new alarm can still be manually armed by my existing wireless keyfobs and has a real time clock to allow it to automatically arm and disarm at preset-able times of the day. One of the issues with the old alarm was never actually knowing exactly which of the 25 sensors went off, by adding an LCD screen to my new alarm build I now get text on the LCD indicating exactly which sensor was activated. I began the process to build an alarm system that could replace my existing alarm and would also provide increased functionality. I stumbled across an instuctable and after some experimenting determined that I could receive the signals from my existing sensors. One day while wondering what I could do to make my alarm functional again, it occurred to me to check if an Arduino could receive signals from the sensors. I am sure there are many people like me who have purchased a GSM/2G alarm system with wireless sensors and were happy with it, however when the 2G/GSM network was turned off where I live, I was left with an alarm system I could no longer program or even set the time on it. Just search for 433Mhz or 315Mhz sensors that use PT2262 or EV1527 coding.

It can also be a complete new project with wireless alarm sensors, such as infrared motion detectors and reed switches, easily and cheaply available online. This project can be built in about half an hour at a cost of about $20.00 if you have existing 433Mhz or 315Mhz wireless alarm sensors. Finished alarm and examples of the wireless PIR, reed-switch and remote key fob.
