Home Automation and Monitoring Projects for Raspberry Pi 
Installation

Welcome to PrivateEyePi
 
This is a Raspberry Pi projects website aimed at the Raspberry Pi enthusiast wanting to build home security/automation systems and at the same time learn programming and electronics. 
 
All software and source code we provide is free of charge can be copied, shared and modified without restriction. There are no charges for the alarm system or any of the projects. The parts you will need are described in the projects and can be sourced on your own or bought from the PrivateEyePi Store.

The Internet Of Things (IOT)

The Internet Of Things has arrived and connecting sensors and controls to The Internet has never been easier. You don't need no be an electronics or software expert or spend a lot of money on proprietary and closed systems to create your own IOT devices and control and monitor them from The Internet. 

Using your Raspberry Pi or our tiny wireless Arduino you can easily build your own sensors and connect them to The Internet. 

Build Sensors

We have many tutorials that show you how to build sensors, or you can build them using hundreds of online tutorials. Some of our sensor tutorials include : 


Using our range of wireless tutorials you can convert your sensor to a wireless battery operated IOT device!

Connect Your Sensor to The Internet

In each of our projects we show you how to, firstly, build the sensor and secondly connect it to The Internet using your Raspberry Pi. We supply the Python code that you download from our web server. 

Create an Alarm System

PrivateEyePi has a cloud based alarm system where you can group sensors using zones. Zones can be activated and alarms triggered based on rules that you define. 

Control

Some sensors, like relay switches, can be controlled through The Internet. You can also control the alarm system through the PrivateEyePi web based dashboard

Monitor

Using our dashboard you can monitor the status of sensors and view temperature and humidity readings in real time from The Internet. Using the PrivateEyePi Analytics you can view historical information. You can see trends using our daily, hourly and detailed data views. 

Trigger

IOT devices are useful for triggering alerts. Using our sophisticated rules engine you can create rules that are processed in real time to create alerts tailored to your needs. You use parameters like sensor values, time of day, days of week, alarm activated/deactivated to define rules specific to individual sensors. The rules can alert you to specific events like a door being opened, motion being detected or temperature or humidity reaching a threshold. You can also use the rules to determine if something hasn't happened. For example you may want to know if no motion has been detected for a time period (popular for monitoring the elderly). Or you may want to know if your garage door was not closed. You can also apply a delay setting to a rule that will only trigger after the rule if valid for a period of time (e.g. garage door open for more than 5 minutes). This is also useful for monitoring the temperature of your house or a fridge where you only want to be alerted after a sustained temperature drop or increase.

Projects:
    • Build a home alarm system and link it to existing door contacts or alarm sensors
    • Connect the alarm system to our server which will feed your own personal WWW dashboard, which is designed for mobile devices
    • Use the dashboard to control your alarm system zones, and view alerts and activity logs
    • Configure your Raspberry Pi to send email alerts to you whenever a alarm occurs
    • Receive alerts and view your dashboard from you PC, smart phone or any device that has a browser and connection to the internet
  •  Webcam Surveillance Projects
    • Create a surveillance monitor using any popular webcam and a Raspberry Pi
    • Create a motion sensor from a webcam and a Raspberry Pi
    • Create email alerts with pictures attached when motion is detected.
    • Build a digital temperature gauge with the highly accurate DS18B20 or DHT22 sensor
    • Display a temperature gauge and graph in Celsius (centigrade) or Fahrenheit on your dashboard
    • Add as many temperature gauges as you like to your dashboard 
    • DHT22 Project
      • Multiple DHT22 sensors can be connected to multiple GPIO pins
      • DHT22 does support humidity which is also displayed on the dashboard
        

  • Wireless Sensor Projects
    • Build a wireless temperature sensor, or a wireless door contact or panic button
    • We have sourced high reliable wireless components that have very long battery life (over 1 million transmits from 1 battery) and very powerful radio frequency signal that can easily operate in and around your home.
    • Highly secure encrypted communication
    • The wireless modules can be programmed with different personalities
    • No knowledge in wireless communications necessary the wireless modules communicate with each other using a light weight easy to understand text protocol (LLAP)
    • Lowest price point on the market for this sophistication
    • Visit the PrivateEyePi store to purchase the components

Wireless Temperature Sensor


  • Wireless Relay Switch Project
    • Switch multiple wireless relays around your house from your Raspberry Pi. You can use it to switch any electrical device (e.g. lights/fans) using a smartphone or browser. 
  • Siren Project
    • Attach a buzzer or external siren to the alarm system
    • This project is dependent on you completing the alarm system project first
    • Auto restart the alarm if it is down
    • Run the alarm as a background process

     
    SwitchBlade

    • Perfect to make your alarm system more robust and permanent
    • 12 GPIO switch connections. Switches are connected to the screw terminals
    • Pads are available on the board for the remaining 5 of 17 GPIO pins. 
    • GPIO header is broken out to twin row pads (convienent and fast access for more than single wire hookups)
    • Construction is very easy (suitable even for children with basic soldering skills)
    • Pick up points for the Pi 3.3v and 5v supply (flexible options for powering your project)
    • Centre power rails (perfect for powering IC's and it eliminates lots of wiring)
    • 2.54mm holes arranged in 3's (a really convenient layout)
  • Switch a light on/off using your smart phone
  • Utilizes a relay switch, GPIO ports, a light weight web server and JavaScipt running on Node.js
  • Everything runs locally on your Raspberry Pi
  • No programming skills required
