In this time when COVID-19 is spreading rapidly, it is essential to maintain social distance and avoid large public gatherings at one place to break the chain of corona infection.  But maintaining this is not easy. Many people, knowingly or...
Geofencing is one of the greatest technologies of the 21st century. It has a multitude of applications such as car tracking and parcel location tracking. Here is a more exhaustive list of the applications of geofencing Can be used...
This simple GSM security switch project is based on Arduino Nano microcontroller (MCU) and SIM800L GSM modem (Fig. 1). The cellular-based alert system is configured to send an SMS in response to a security switch action. When the security sensor...
COVID-19 is a highly infectious and easily contractable virus that can become extremely hard to control once it begins to spread. Social isolation/distancing is one of the most important and effective steps one can take to break the chain...
This is a concept DIY that helps to detect the symptoms of COVID-19, so as to help individuals quarantine themselves and practice social distancing. The DIY works by detecting the basic symptoms of the virus, which are: increased body...
This project can be used to control up to four industrial electrical appliances with the help of a joystick and an Arduino Nano board. The block diagram of the joystick-controlled industrial automation system is shown in Fig. 1. The circuit...
Accidents due to drunk driving are a common occurrence in metropolitan cities. Albeit helpful, constructing checkpoints at different locations is a cumbersome job and takes a lot of timing, as does stopping and checking every potential drunk driver. To...
Monitoring of various process variables such as temperature, pressure, viscosity, humidity, pH and flow-rate is very important in steel plants, petrochemical and other such industries. The human-machine interface (HMI) at the operator station displays a continuous and real-time trending...
We are all familiar with how notice boards in schools, offices, colleges and railway platforms look like. But have you ever wondered how they work and how you can make such a board by yourself? So, today we are going...
Today, we are going to make an ‘all-in-one’ measurement device/instrument, which consists of a digital inclinometer, compass and protractor. It also includes a health monitoring system that can provide data about temperature, oxygen levels and heartbeat. All these features come...
