IoT WiFi DIY Motion Detector With E-mail Notification Using PIR Sensor and ESP8266

In this project I am using the ESP8266 WiFi module and PIR sensor motion detector to get e-mail alerts if someone enters the room while I am away. I am using GadgetKeeper Cloud Platform to bing e-mail notifications with PIR Sensor. I have choose GadgetKeeper Cloud Platform because it's FREE and easy to use. The whole project costed me around $7 and was pretty easy to build.

NOTE: to upload code to ESP8266 first connect GPIO0 pin to ground, reset esp and then upload code. After uploading code GPIO0 can be disconnected again.

Download Arduino IDE from Arduino.cc (1.6.4 or greater) - don't use 1.6.2! You can use your existing IDE if you have already installed it

You can also try downloading the ready-to-go package from the ESP8266-Arduino project, if the proxy is giving you problems

Enter

http://arduino.esp8266.com/stable/package_esp8266com_index.json

into Additional Board Manager URLs field in the Arduino v1.6.4+ preferences.

Next, use the Board manager to install the ESP8266 package.

The required libraries can be downloaded from following link:

Time.h

All other required libraries are available as standard libraries with the IDE.

Installing Additional Arduino Libraries guidelines can be found on official Arduino site.

After successfully creating account on GadgetKeeper, go to console and create the "Alarm" thing first.

After successfully creating Alarm thing write down your Thing ID.

if you need detailed "point and click" UI instructions how to create thing see "Create, Read, and Write Property" on GadgetKeeper Documentation.

Create Motion detected event for Alarm thing in GadgetKeeper Console.

1. In the "Thing: Alarm" tab, open "Events"
2. Click "New" to open "Create Event" dialog
3. Set name to "Motion detected"
4. Select "boolean" as the data type for this event
5. Save event

if you need detailed "point and click" UI instructions how to create even see "Create Event And Trigger" on GadgetKeeper Documentation.

Create Mail notification trigger for Alarm thing in GadgetKeeper Console.

1. Open "Triggers" in the "Thing: Alarm" tab
2. Click "New" to open "Create Script Trigger" dialog
3. Set name to "Mail notification"
4. Select "Motion detected" as the event used for the trigger
5. Save trigger by clicking "Save"

if you need detailed "point and click" UI instructions how to create even see "Create Event And Trigger" on GadgetKeeper Documentation.

Add script to Mail notification trigger for Alarm thing in GadgetKeeper Console.

1. Open "Triggers" again in the "Thing: Alarm" tab
2. Select "Mail notification"
3. Click "Edit Script" button to open "Edit Script Trigger" dialog
4. Insert the following script in the text area (email name may be edited):

function onEvent(event){
if(event.value == true){

smtp.send("user@gmail.com", "Motion detected!")

}

}

5. Save the trigger script by clicking "Save"

if you need detailed "point and click" UI instructions how to create even see "Create Event And Trigger" on GadgetKeeper Documentation.
