Guys I spent a long time trouble shooting with this project. there were various issues. I am going to list some of them to help you skip burning the midnight oil.

1) Check the NodeMCU pins if they are giving the correct i/o as you are assuming, for e.g. lets say that you are taking the pin no 4 (GPIO) as an input pin. Now by default this pin should read ........ low that't right but for some reason it reads high even after initializing the pin to input. test it!! the consequences of not testing are long and not so fun.

2) Using a direct HTTP get/post method instead of using a visualizing function provided by BLYNK or Thinger.io. My deep respect to these guys for building amazing services and platforms.

My 2 cents :The reason being that the PIR output stays high for a couple of sends and you need to bring in necessary delay to avoid sending multiple emails. with some services like BLYNK this delay causes an issue. as it is required to call that function once is 6 or 7 sec. This is my experience I could be wrong.

3) Once it satisfies the condition from the if loop, call a function, instead of writing everything with the loop. This brings clarity to the code and help in trouble shooting. Again this is my feeling.

You could adjust the sensitivity of the PIR to reduce the time it stays high. something you could consider..

Have fun making this IOT device..

The ability to trigger an email is programmed or setup at the IOT platform for this product we are using the Carriots IOT platform. Its quite a mature platform with many features. spend some time in the platform to acquaint yourself with the functionalities and how to use them

All the hard work has paid off. You have a working IOT device to sense motion and alert the user with an email over wifi. Pretty darn good!!!

Obviously this could be programmed to call, or a text or a alarm to the cops or whoever, the apllications a re numerous.

We will go through the demo and see this IOT device in action.

Time to call all your folks and arrange some popcorn.

If you are able to pull this off, you are well beyond the beginner level and now the world is your oyster, you have understood the fundamental aspects of working with Micro controllers, Wifi, Ethernet chips, relays, IOT platforms and also hooking up actual devices.

Nice work !!!!
