In this internet of things tutorial, I have shown how to make IoT based project using an MQ2 gas sensor, rain detector & ESP32 NodeMCU with Blynk Notification for beginners. With this simple IoT project, you will get an Alert in mobile notification and email, if there is any gas leakage or rainwater detected. So this is a very useful IoT-based project on home safety you can make in the home with the New Blynk IoT platform.
During the IoT tutorial video, I have covered the following topics:
01:15 How this Blynk IoT sensor project works.
02:52 Required Components for the Blynk IoT project.
03:14 Circuit of the IoT project using ESP32.
03:50 Circuit of the IoT project using ESP8266 NodeMCU.
04:09 How to set up the Blynk cloud platform.
08:13 Add new device in Blynk IoT platform.
08:52 Source codes for the Blynk IoT project.
12:27 Set up Blynk IoT app mobile dashboard.
13:15 Testing the IoT sensor Project.
Required Components for the internet of things project:
1. ESP32 or NodeMCU
2. MQ2 Gas sensor
3. Rain sensor module
4. 1k 1/4 watt resistors (2no)
5. 5-mm LEDs (2no)

During the video on IoT mini-project, I have explained the source code in detail, so you can easily connect multiple sensors with the ESP32 or NodeMCU and monitor the readings from the digital or analog output pins in the Blynk app.
I have also shown how to set up Blynk Notification in the Blynk cloud in the source code.
So this is a simple IoT project for beginners or you can make it for the final year project. I have used all the FREE resources, so anyone can make this Blynk project.
