2020 has been a rollercoaster year for businesses but it has also given a much-needed push for innovation. Industry 4.0 is making a strong case for itself, and in 2021, the nature of manufacturing innovations will take centre stage. In that regard, let's look at five key factors set to impact the manufacturing industry in 2021 and beyond. Table of Contents 1 Introduction 2 Smarter … [Read more...]
IoT Home Automation: Getting Started
If you have multiple houses and want to remote control the electrical devices from anywhere on this earth with a decent UI then this article is for you. When we need to control just few bulbs or motors then we can use ready to use smart sockets. A DIY alternative to it is using IBM IoT and ESP32 to control the AC powered appliances. These ways are cost-effective, commercial solution provides a … [Read more...]
Samsung Galaxy Watch LTE Review
This watch is quite different as it contains the circuit for having a SIM. That makes it an independent device like a standalone smartphone. You can make calls, receive calls, use data services without Bluetooth or WiFi connection with the smartphone. It is a master on a network, not a slave. It is capable to use NTP like ESP32 Arduino or smartphones with data connection or computers with active … [Read more...]
Connect Android CLI (Termux) to IBM Watson IoT Like Raspberry Pi
Android smartphones can be made to partially work like Raspberry Pi like single board computers. That is probably useful for different reasons. To follow the steps of this guide, you need to read our previous guide for the basic setup with Termux. Although in that guide, we mainly focused on how to use Node-RED, there are is the installation of termux-api and some useful links. Any Android device … [Read more...]
How to Use Android Smartphone as IoT Device (Termux, Node-RED)
We can use any modern Android Smartphone something like a Raspberry Pi with a camera, all the sensors & send the collection to any IoT platform. Although it will sound like a complex work it is easy because of a lot of development by many hundreds of developers. There are ready to use Android applications which does the similar job from GUI and connect with IoT platform like IBM Watson IoT … [Read more...]
Raspberry Pi Zero For Low Cost IoT Projects
There is nothing to disagree with the advantages and low cost of microcontrollers such as ESP32. But, by design ESP32 can not perform complex computing works. Adafruit's CircuitPython and MicroPython are good way to work with Python on microcontroller. But, there are many use-cases where using MicroPython/CircuitPython pushes to the limit. Cost of boards from Adafruit and Arduino are not cheap … [Read more...]
What is the Relationship Between Cloud Computing and IoT?
Virtualization is the technology behind Cloud Computing. Cloud Computing itself has different service models. We work on with self-hosted server with Infrastructure as a Service (IaaS) model of cloud computing. IaaS is used as a replacement of traditional virtual private servers, dedicated servers, shared servers for easiness, more control and lesser cost. Even at the end of 2019, the cost of a … [Read more...]
Control Multiple AC Appliances With One ESP32 Arduino
The result of this guide will be a local control panel with ESP32, pushbuttons, LED indicators, relays which can control the connected AC appliances by the simple pushbutton press. When connected to Wi-Fi, it will be able to control the thing over the internet with simple HTTP cURL commands. This guide and code can be used for home automation or creating smart power outlet. Single relay version of … [Read more...]
URL Format For Sending Commands Over HTTP (cURL) to IBM Watson IoT
HTTP commands open up wider way to control. This is the corrosponding GitHub repository with a basic example matched with this guide. Already we have shown the serious usages of the method through our Controlling AC Powered Appliances With ESP32 guide. Here is a Discussion on URL Format or Sending Commands Over HTTP (cURL) to IBM Watson IoT. IBM's platform is configured to accept events from … [Read more...]
How to Control Multiple Relays With Single Arduino ESP32?
One regular reader of this website asked us how we can control multiple relays with single Arduino ESP32? This article will not give any direct answer. This is a theoretical article discussing how multiple channels on MQTT can be created so that we can separate matters like temperature and humidity from a DHT11 sensor. Normally we connect DHT11 with IBM Watson IoT in a raw manner. In our that … [Read more...]
Influence of the Internet of Things (IoT) on Retail : Part IV
This is the forth part on the series on Internet of Things (IoT). The use of IoT technologies in retail enables a multitude of new opportunities and offers great benefits. At the same time, however, it also brings dangers with it. The main benefits are the economic advantages for the dealer and the added value for the customer. However, the security of the Internet of Things, as well as the … [Read more...]
