IoT Projects for final year – IR sensor Notification IoT


Hey guys, welcome back to Our website again.

we have the latest IoT project for final year students. Final year students search for ideas on IoT projects for these guys we uploaded this video.

simple we are uploading the data on the server. the server is the storage where we store the data in real-time. before this,

we have uploaded a very good project for your IoT home automation. you should check all our IoT projects. This is only the way to monitor our activity over the internet from anywhere in the world.

IoT based project is in trending nowadays coz everything is controlled by the internet. we have mobile, pc and laptop to control the thing over the internet but on the other side, we need a system which can connect to the server or the internet.

What is iot project using ir sensor?

Here we are using an IR sensor with the esp 8266. if someone comes in front of the IR sensor then it will detect and send information to the server.

and notify you on your mobile phone. we will share all the information about the esp8266 ir remote. you need to follow all the given instruction

Here we are having an application named Blynk application. which we need to download from the play store. And afterward,

we need to make a few fastens according to the prerequisite. we will make the association as given underneath and afterward transfer the code into the ESP8266.

and afterward when we squeezed the catch in our IoT Based project on the portable screen then the application will send the information to the worker and as indicated by the code, the worker controls the gadget as per the information. this is how the entire framework functions?

Components Required

  1. NodeMCU (esp8266)
  2. Breadboard
  3. jumper wires
  4. Connecting cable
  5. IR sensor

Connection Table

Nodemcu esp8266 IR Sensor
Vin, 3V3VCC
D1 PinOUT Pin

Here we added an IR sensor with the nodemcu and will send this data to the server and the server will send this data to the mobile phone and show the value.

we will use the Blynk app in which the data shows. all the steps we will upload here. Following all the steps it’s pretty simple. This IoT project is the easiest and coolest project.

IR IoT Projects Code:- 

 // ESP8266 LIBRARY  
 // IR Sensor Connect to D1 PIN  
 #define BLYNK_PRINT Serial  
 #include <ESP8266WiFi.h>  
 #include <BlynkSimpleEsp8266.h>  
 BlynkTimer timer;  
 char auth[] = "6Stu2qds1ijIEsWTpt6NhDsQYnnXjAxt"; //Auth code sent via Email  
 char ssid[] = "DESKTOP"; //Wifi name  
 char pass[] = "asdfghjkl"; //Wifi Password  
 int flag=0;  
 void notifyOnIR()  
  int isButtonPressed = digitalRead(D1);  
  if (isButtonPressed==1 && flag==0) {  
   Serial.println("Some one inter in the room");  
   Blynk.notify("Alert : Some one inter in the room");  
  else if (isButtonPressed==0)  
 void setup()  
 Blynk.begin(auth, ssid, pass);  
 void loop()  

Upload the given code into your esp8266. and if you have trouble with uploading see our latest esp code uploading tutorial 

After uploading the code you need to follow the given instruction.

App installation & Setup

  1. May you include to turn IR detection on or off from mobile phone. This would be great as a simple alarm system. Thank you for your great projects.
