Introduction
In this tutorial, we will learn to Interface BME680 Environmental Sensor with Arduino microcontroller. The BME680 is an Integrated Environmental Gas sensor that measures ambient temperature, relative humidity, barometric pressure, gas (VOC) & IAQ. We know pressure varies with altitude, BME680 can measure the approximate altitude values. Besides these, using some mathematical equation relating to temperature and humidity, we can also derive the Dew Point. Simply, we can get all these parameters from Arduino Adafruit BME680 Library & Code.
The BME680 is a highly upgraded version of the BMP180 and BME280 with additional features. Before this, we created some weather station projects using the BME280 based on the ESP32 as well as ESP8266. We also built a wireless weather station using BME280 and Lora. Here we will implement the same weather station with BME680 and Arduino. Besides the weather station, we will also measure IAQ or Air Quality Index, or Gas VOC.
Components Required
The purchase link of the BME680 sensor and Arduino board is given below, along with some additional essential components.
BME680 Integrated Environmental Sensor
The BME680 is a digital 4-in-1 sensor measuring gas, humidity, pressure, and temperature based on proven sensing principles. The gas sensor on the BME680 can detect a variety of volatile organic compounds to monitor indoor air quality. The sensor has high linearity and high accuracy.

This tutorial is all about IoT Based Voice Controlled Home Automation Using NodeMCU & Android. Previously we have made similar types of IoT based Home Automation Projects to control relay from NodeMCU web server. We have used Asyncwebserver to control home appliances from a web browser. But, today we will build our own Home Automation Android App using MIT App Inventor. Install it on Android smartphones and control our home appliances using voice commands as well as buttons.

This IoT based voice-controlled home automation project, allows you to interface 2/4/8 channel relay with NodeMCU ESP8266 and control different Appliances like Lights, Fan, AC cooler, Pump, etc. We will use an Android app having Several ON/OFF Buttons and voice-controlled system to send a signal to NodeMCU in order to control relay output. We will assign an IP address to NodeMCU and assign the same IP Adress to the Android App. Because our Android phone and NodeMCU should be connected to the same network for access control. theiotprojects.com/iot-voice-controlled-home-automation-n...
Overview: BME680 IAQ Monitoring on webserver & OLED Display
In this project, we will make the Indoor Air Quality Monitoring with BME680 & ESP8266 Webserver and 0.96" SSD1306 OLED Display. We will use the advanced BSEC library for BME680 and monitor its parameters including IAQ on OLED Display and ESP8266 web server simultaneously. So, that you can monitor the sensor values remotely from your local network.
In our previous projects, we have interfaced Arduino with an integrated BME680 Environmental Sensor. Further, we made an IoT-based Indoor Air Quality Monitoring system on the Blynk IoT Cloud. But the drawback of that project was, we could not calculate the IAQ value i.e. Index of Air Quality, C02 equivalent, and percentage of (VOC) Volatile Organic Compound. we could only measure the environmental parameters like temperature, humidity, pressure, altitude, dew point, and Gas Resistance.
So in this tutorial, we will use a highly advanced BME680 Library called BSEC library, Which is now supported by NodeMCU ESP8266 and ESP32 Development Board. With the help of this library, we can measure the Temperature, Humidity, Pressure, value of IAQ, equivalent carbon dioxide, and Total volatile compound. SSD1306 0.96” OLED Display is used to monitor environmental data. We can also use ESP8266 Webserver to remotely monitor those values. The ESP8266 connects to your WiFi network & uploads the data regularly to the webserver.
