Firstly, we will learn about BME280 and how to connect with ESP8266 NodeMCU. Secondly, we will see how to install the BME280 library in Arduino IDE. Next, we will work … Read more
In this user guide, we will learn how to publish sensor readings to ThingSpeak using the ThingSpeak Arduino library and ESP8266 NodeMCU. We will use Arduino IDE to program our ESP8266 NodeMCU board which will be connected to a temperature, humidity, and pressure sensor. Our main aim is to transmit these sensor readings to ThingSpeak … Read more
In this user guide, we will learn how to publish sensor readings from ESP32/ESP8266 to Google Sheets using IFTTT as a third-party service. This guide will be helpful for the users who want to access data for a predetermined amount of time and also store it appropriately. Any preferred sensor, such as DS18B20, BME680, and … Read more
In this user guide, we will learn to send sensor readings to Google firebase and also on Android app through Google Firebase using ESP8266 NodeMCU and Arduino IDE. We will make our personal ESP8266 IOT app by using Google Firebase and MIT App Inventor. Previously, we used the Blynk application to control ESP32’s output (Control … Read more
In this tutorial, we will learn to program ESP32 and ESP8266 boards with VS code by using the Pymakr extension available in visual studio code. As we have seen in previous tutorials, we have learned to program ESP32 and ESP8266 boards using various IDEs. Recommended Components The following components are used in this project or … Read more
In this user guide, we will learn about web server with Server-Sent Events (SSE) protocol. Using this technique, we will build an ESP8266 controlled web server that will automatically update sensor readings regarding temperature, pressure, and humidity to all connected web clients. Our client will receive automatic updates from the ESP8266 board with SSE through … Read more
In this tutorial, we will learn to interface the BME680 sensor with ESP8266 NodeMCU using Arduino IDE. The BME680 environmental sensor, which is used to measure ambient temperature, barometric pressure, relative humidity, and gas (VOC) or Indoor air quality (IAQ). We will learn how to interface it with ESP8266 NodeMCU using Arduino core programming. For … Read more
In this tutorial, we will learn how to get the current date and time from the NTP server with the ESP8266 NodeMCU development board and Arduino IDE. In the data logger applications, the current date and timestamp are useful to log values along with timestamps after a specific time interval. The time.h header file provides … Read more
In this tutorial, we will learn how to reconnect the ESP8266 NodeMCU board to the WIFI network when it temporarily loses connection. Through different methods, we will demonstrate this functionality. Hence, this guide will be highly useful to avoid the nuisance of constantly losing network connection due to many reasons such as WiFi router restarted, … Read more
