IOT Based Food Spoilage Detection System Detailed Circuit Connections and Program | IOT Project.

Components used are:
Arduino UNO R3, MQ4 Methane Sensor, NodeMCU, Buzzer, Green LED, Red LED, Breadboard, Connecting Wires, Jumper Wires etc.

It is not required to buy every component separately.You can buy EPICTAC electronics kit which consists of Arduino UNO R3, Buzzer, Green And Red LEDs, Connecting And Jumper Wires(Male or Female or both), Breadboard, and few other components which are not required in this project but the separate price for components is too much,so you can opt for this.Other remaining components can be bought separetly.Everything is available on Flipkart.I have done the same.



For more details and the reference I am providing this link which is very useful.It consists everything right from arduino and nodemcu programming to the the circuit connections and also every details of blynk app setup.

I have done few changes in the code it is not same as provided in the above link.You can follow the same or mine.It is shown in the video itself.

Here's the link to my program:
