Overview: IoT Fire Detector & Extinguisher
Nowadays, Fire detecting and Alerting system are very common in banks, offices, homes, etc. They usually detect fire and alert people with a siren. But, what happens, when nobody is there to listen to the Alarm. Like when nobody is at home or office. So, to inform the authority about fire incidents and to automatically extinguish the fire. We have made this IoT Fire Detector & Automatic Extinguisher using the NodeMCU project. This project can be further modified to notify the fire control department automatically.
This IoT based project detects the nearby flame using an Infrared Flame Sensor and then NodeMCU Tiggers the relay to extinguish the fire automatically. It also informs the authority using IoT Blynk Application. With the help of this project, you can easily understand the concept of a fire detector and alert system.
Requirements for IoT Fire Detector and extinguisher system
The following are the components required for making IoT based fire detector and automatic extinguisher system using NodeMCU:

Now let's start assembling all the components for IoT based Fire detector and automatic extinguisher system using NodeMCU(ESP8266) and flame sensor.
Circuit Diagram of IoT based fire extinguisher project
- First of all, connect the Vin pin to the positive rail on the breadboard.
- Then connect GND Pin to the negative rail of the breadboard.

Today in this tutorial, we will learn to interface the BME280 sensor with the NodeMCU ESP8266 development board, then Monitors its parameters like temperature, humidity, barometric pressure, altitude, and dew point on the Blynk IoT Platform. This IoT Project provides your NodeMCU ESP8266 board the ability to sense the environment with a BME280 Barometric Pressure sensor. Overall, we are building ESP8266 & BME280 based IoT Weather Station.

- Wrapping Up
The BME280 is a widely used sensor that measures temperature, humidity, barometric pressure, dew point, and altitude. Actually, it is pre-calibrated and is relatively simple to use. Because you don’t require any extra components. So you can start measuring its data using NodeMCU ESP8266 and BME280 sensor.
We are from the Internet of Things (IoT) Generations. These days, we control our home appliances like air-conditioners, room heaters, water heaters, etc. remotely from anywhere. But for every Wi-Fi-based IoT-enabled device, we require uninterrupted Internet/Wi-Fi connectivity. The problem of Low Wi-Fi signal is very common due to interference from room to room or floor to floor. Many people face this problem in their daily lives. Everything needs the internet. Smart TV, smartphone, laptop, desktop computer, but you just have one router to provide a wireless connection on a house. Don't worry we will build the cheapest and Portable Wi-Fi Repeater using ESP8266 NodeMCU.
So, the question is How can we access the internet in every corner of the house? If you have a big house single router is not enough to cover this range! Each footstep lowers the Wi-Fi signal. And it's not good for a multi-story building So what solves this problem?
The one and only solution is Wi-Fi Repeater !!!!! Yes, repeater solves this problem.
What is Wi-Fi Repeater?
A Wi-Fi repeater or expander is used to expand the coverage area of your Wi-Fi network. It works by receiving your existing Wi-Fi signal, amplifying it and then transmitting the enhanced signal. With a Wi-Fi repeater you can effectively double the coverage area of your Wi-Fi network - to reach the far corners of your home or office, on different floors, or to expand coverage in your yard.
