Hello friends, I hope you all are having fun. Today, I am going to share the 9th tutorial of Section-III in our Raspberry Pi 4 Programming Course. In the previous tutorial, we interfaced an air pressure sensor BMP180 with Raspberry Pi 4. In this tutorial, you'll learn how to interface an MQ-2 gas sensor with a Raspberry Pi 4. Many apartments, residences, and workplaces rely heavily on these gas sensors to detect smoke or gas and alert the appropriate personnel in an emergency. In addition to gas and smoke, this sensor is sensitive to various odorous gases.
Project DescriptionToday, we will interface a gas sensor MQ-2 with Raspberry Pi 4 and will display the values on Raspberry Pi Console Window.

Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you What are the main features of embedded operating systems? In order to operate, most of our digital home appliances, industrial machines, vehicles, and all other sorts of machines require embedded Operating Systems that run all software that controls functionality. The reason why unitary control of the processes is necessary, among others includes efficiency. Instead of managing every embedded system separately, an embedded OS controls all programmable and fixed hardware functions. Even though they are widely in use, the full spectrum of features that these types of software have to offer is not familiar to a broader array of the public. That is why, in this a ...
Update: Here are the latest versions of this library: PIR Sensor Library for Proteus V3.0 and PIR Sensor Library for Proteus V2.0.
Hello friends, hope you are doing well. Today, I will share a new PIR Sensor Library for Proteus. PIR Sensor module is not available in Proteus so we can't use it in
our simulations. But today, I will share a new PIR Sensor Library
for Proteus which can easily simulate PIR Sensor in Proteus software.
We are quite happy that we are helping engineers by sharing these new Proteus Libraries.We all know about PIR Sensor but if you don't know then first read Interfacing of PIR Sensor with Arduino.As a quick review, a PIR sensor is used to detect motion in the environment and is commonly known as a motion sensor. It's quite helpful in security projects ...
Printed circuit boards are the most important and basic component of the electronic industry. These boards have made it possible to create and run circuits on every level and have served as the backbone of any electronic device. With the growing demand for technology, PCBs have gone through multiple evolutions. The transformation of PCBs has made it possible to create innovative and better electronic circuits.
Today, we are talking about the emerging trends in PCB that are reshaping electronic circuits and the components used in innovative designs. But before this, it is important to understand the importance of using the emerging trends for the circuits.
Importance of Using Trending Technologies in PCBs
PCBs are versatile components, and not all PCBs are ideal for a particular type ...
Hello everyone! I hope you will be fine and having fun. Today, I am going to give a detailed Introduction to Relay. In this tutorial, we will learn the basics of relays, the working principle of relays, the types of relays and their applications in detail. A relay is a simple automatic switch that opens and closes the circuit(either electronically or mechanically) based on its input signal. A relay is an electromechanical switch that uses electromagnetism from a small current or voltage to switch higher current or voltage for different appliances. When a relay is in a Normally Open (NO) state, no current passes through it and when the relay is energized, the current starts to flow and we can say the relay is in a Normally Closed state. You should also have a look at Relay Interfacing with ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Increase EF Core Performance for Saving Multiple Entities? EF Core works well for simple CRUD operations but for saving multiple entities EF Core provides poor performance. So, today we will use a third-party EF Core extension named "Z.EntityFramework.Extensions.EFCore", designed by ZZZ Projects, which will increase the EF Core performance significantly. I will be using a BulkSaveChanges Method of this library which is specifically designed for saving bulk data in an SQL database.
ZZZ Projects is a trusted company and has designed numerous .NET libraries, a few having downloads in millions. So, you can completely trust this extension library.
Here' ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new exciting post on Send SMS with SIM900D in Proteus ISIS. In my previous post, I have shared the new GSM Library for Proteus, which is the first ever designed library for Proteus, and I am quite excited while sharing its features. So, today, we will use this GSM Lirbary for Proteus and we are gonna send sms with Sim900D module available in that library. We are gonna design this whole project in Proteus ISIS.
If you wanna implement it on hardware then you must have a look at Send SMS with SIM900D module with Arduino which is designed in real hardware but today we are gonna just do the simulation part. Iam not gonna use any Microcontroller today. Inst ...
Hey pupils, Welcome to another lecture of this series on signals and systems, and this is the time to learn an interesting topic in which you are going to learn about the convolution of the signals. In the previous sessions, we have learned basic operations on the signals, and this time, you are going to know the convolution of the signals and different criteria that are related to this topic. Have a quick view of the concepts that will be clarified in this lecture: What is convolution? What are some basic types of convolution? How can you define the properties of linear convolution? How can you implement convolution in MATLAB using function and without function? What is the difference between linear and circular convolution? What is the convolution of signals? Convolution is ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share a detailed tutorial on How to monitor your System on Mac with Istat. Every year, consumers of Apple products are becoming more and more. Their hearts conquer the functionality and security of devices. When you work on your Mac, you do not just spend time with pleasure, but really enjoy the process. But like any gadget, your Mac requires attention and care. There are a large number of applications that may help you be aware of everything that happens with your computer. They are needed in order to react in time to some problem and correct it. We will talk about one of these applications in this article.
It's about a popular and very useful iStat Menus utility th ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM335. LM 335 is basically an Integrated Circuit (IC) for precise temperature sensor. LM-335 operates on a current range 400uA-5mA having resistance less than 1 ohm. At 10mV/K, its absolute temperature becomes directly proportional to the breakdown voltage.
LM-335 operates as two terminal zener diode. At the temperature ranging from -40 degree Celsius to 100 degree Celsius, LM 335 can be used for each type of temperature sensing purposes. This device is available in different dimensions and in different sizes. LM-335 is most commonly available in the market due to its unique features including e.g. large temperatur ...
