Here is the source code for the IoT Smoke & Gas Detector System using ESP8266. You can add a description of your project if required.For creating a project, first, you have to click on the New Template. In our case, it’s a Smoke & Gas Detection System. Create an account or simply sign in if you created the account earlier.Īlso Read: Home Automation using ESP32 & Blynk 2.0Ī template is a project in which we can create a web and mobile dashboard for specific hardware. In order to monitor the Smoke, LPG, and CO Data on Blynk IoT Server, you first need to set up the Blynk IoT Cloud dashboard. Now let’s set up the Blynk IoT Platform to test this project. Lastly, I connected the buzzer’s positive pin to the D6 pin of the NodeMCU and its negative pin to the Ground pin. After that, I connected an LED anode pin to the D5 pin and its cathode pin to the ground. Its SCL and SDA pins to the D1 and D2 pins of NodeMCU. ![]() After that, I connected the I2C OLED VCC pin to the 3.3V pin of NodeMCU and its ground pin to the ground. VCC and GND are connected to the 3.3 Volt and GND pins of ESP8266 respectively. Here I have interfaced the MQ2 sensor Analog Pin A0 pin with the A0 pin of ESP8266.
