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.

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.

Overview: MAX30100 ESP8266 Web Server
In this project, you will learn to make MAX30100 Pulse Oximeter Webserver using NodeMCU ESP8266. In our previous project, we have made an IoT based Pulse oximeter in which Pulse rate and Sp02 level are shown in OLED Display and Blynk Application. But in today's project, we will monitor Heart Rate and oxygen saturation (Sp02) values on the ESP8266 NodeMCU Web Server. You can monitor those values from any device which has wifi support and browsing capabilities.
In today's project, you will learn:
- What is the MAX30100 sensor and how it works?
- How to interface the MAX30100 Pulse Oximeter sensor with ESP8266?
- Program ESP8266 board using Arduino IDE.
- Create a beautiful local webserver to display BPM and Sp02 parameters.
Components Required
To make an ESP8266 based MAX30100 Pulse oximeter, you will need the NodeMCU ESP8266 Development board. A MAX30100 Pulse oximeter sensor, few jumper cables, and a breadboard. You can buy all these components from the Amazon link provided below.
Working of MAX30100 Pulse Oximeter Sensor
The sensor has two LEDs, one emitting red light, the other emitting infrared light. Infrared light is required for pulse rate. But, Both red light and infrared light are required for measuring Sp02 levels in the blood.
When the heart pumps the blood, the oxygen level is increased because there is more blood. But, when the heart rests, there is a decrease in oxygenated blood.

In this project, we will make an IoT based Decibel meter with NodeMCU ESP8266 & Sound Sensor then monitor the sound level intensity on the Arduino IoT cloud.
Overview
Generally, the sound level meter is used to measure the sound intensity of the surroundings. Condenser microphone combines precision with stability and reliability, hence it is best for the decibel meter. This device is sometimes called SPL (Sound Pressure Level) Meter because the diaphragm of the microphone responds to changes in air pressure caused by sound waves.
Decibel meters are commonly used in studies for the identification of different kinds of noise pollution, especially for industrial, environmental, mining, and aircraft noise. This DIY project is helpful for monitoring loudness in dB.
In this IoT project, we will make a simple Decibel Meter using ESP8266 & Sound Sensor. We will also use a small 0.96” I2C OLED Display to visualize the noise intensity locally. The Sound Sensor will detect the sound and convert it into an analog voltage which is read by Nodemcu ESP8266. Then Nodemcu connects to WiFi Network and uploads the data to Arduino IoT Cloud. So, you can monitor those parameters remotely from anywhere in the world.
