Hi Guys! Glad to have you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Types of Internet of Things (IoT). IoT has been around for a while and has started making the headlines over the past couple of years. Some people experience IoT in their everyday life but are not aware of what it actually is. When physical objects “things” interact with the digital world, IoT is born. In simple words, it’s the network of connected devices integrated with sensors that work to exchange and share data over the internet. It is a rapidly growing technology with more than 18 billion connected IoT devices today and with the inception and boost of 5G technology this figure is expected to touch 125 billion by 2030. Experts say we may witness the stage when everything ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention. Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32. We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to access Firebase (a real-time database) to store and read values or data with ESP32. It is Google’s mobile application development platform that can be used to can access, monitor and control ESP32 from anywhere in the world with its (firebase) real-time database. What is Firebase? Firebase real-time database is a development platform provided by Google which included multiple services to manage and authenticate data. Firebase is basically a mobile and web app development platform I as works great with Android APIs) that includes features like firebase cloud, real-time data and Firebase authentication etc. As per Firebase’s official documentation ( https://firebase.google.com/docs/database ), whenever a us ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to interface the BMP280 sensor with the ES32 module to get temperature, pressure and altitude readings. Later, in this tutorial, we will also discuss how to upload these sensor readings to a web server. BMP280 BMP280 or Barometric pressure sensor is a module used to measure temperature pressure and altitude. The small size and low power consumption feature of this sensor makes it feasible for battery-powered devices, GPS modules and mobile applications etc. Fig. 1 BMP280 Sensor The BMP280 is the product of BOSCH which is based on Bosch’s proven Piezo-resistive pressure sensor technology featured with high accuracy, long term stability, linearity and high EMC robustness. BMP280 is the successor of the BMP180 ...
Hello readers, I hope you all are doing great. ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT. Project Overview In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32. Fig. 1 To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD). We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to display the hard-coded data (in the ESP32 module) o ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to update a webpage using Server-Sent Events and the ESP32 web server. What is Server-Sent Events (SSE)? It is a server push technology that enables the client devices to receive automatic updates from a server over HTTP (Hypertext Transfer Protocol) connection. SSE also describes how the server can initiate data transmission towards the client once an initial connection with the client has been established. We have already posted a tutorial on how to implement Web socket protocol with ESP32 which is also a protocol used to notify events to a web client. Both the Server-Sent Events (SSE) and Web-Socket technologies seem to be quite similar but they are not. The major difference between the two is that SSE is ...
ESP32 module comes with multiple inbuilt features and peripheral interfacing capability is one of those features. ESP32 module also consists of an inbuilt temperature sensor, but that can only measure the temperature of the ESP32 core not the temperature of the surrounding environment. So it is required to use a peripheral sensor to measure the temperature of the surrounding environment like home, garden, office etc. Hello readers. I hope you all are doing great. In this tutorial, we will learn how to interface DHT11 (temperature and humidity sensor) with the ESP32. Later in this tutorial, we will discuss how to share the sensor readings obtained from the DHT11 sensor to a web server. Before moving towards the interfacing and programming part, let’s have a short introduction to the DHT11 s ...
The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet. To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers. Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications. Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR se ...
Hi Friends! Hope you’re well today. In this post, I’ll walk you through What is Edge Computing? Edge computing is the extension of cloud computing. Cloud computing is used for data storage, data management, and data processing. While Edge Computing does serve the same purpose with one difference: edge processing is carried out near the edge of the network which means data is processed near the location where it’s produced instead of relying on the remote location of the cloud server. Confused? Don’t be. We’ll touch on this further in this article. Curious to know more about what is edge computing, the difference between edge computing and cloud computing, benefits, and applications? Keep reading. What is Edge Computing? Edge computing is the process where data is processed near or at the p ...
