Hi readers! I hope you are doing well and want to learn something new. Have you ever asked why our homes feel warmer when it’s cold and cooler when it’s hot out? Welcome to learn some of the secrets of HVAC Systems. Today, we will learn about the HVAC System.
Specific requirements of HVAC refer to all installations providing comfort as well as keeping a good air condition indoors for residential, commercial, and industrial buildings. It discusses the necessary components for comfortable air in your home: temperature, humidity, and cleanliness through heating, cooling, and fresh air. Most HVAC systems are based on thermodynamic principles and operate using the refrigeration cycle to transport heat through the phases of heat transfer by compressing, condensing, expanding, and evaporating re ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I will provide you document on detailed discussion about Introduction to LM224. LM-224 has four internal builtin operational amplifiers. These amplifiers are frequency compensated. The basic purpose to design these type of device is to operate it from a single power supply sources. Moreover, they are also able to perform different tasks using split power supplies. Magnitude of power supply and the current current drain both are independent of each other.
LM-224 has a very wide range of application areas which include DC gain blocks, transducer amplifiers etc. LM 224 has a large number of amazing features include wide power supply ranges, large bandwidth, low input offs ...
Hi friends and hope you are doing very well. Today we would like to take one tutorial which is very essential in the industry which is analog input processing for handling analog measurements of physical signals like temperature, humidity, pressure, distance, flow and level of liquids, etc. Typically, sensors produce two types of analog signals to represent the equivalent measured signal which is current and voltage signals. The currently produced signals would be within the range of 4-20 mAwhile voltage signals are in the range of 0-10 v. because, that output signals represent physical signals, the limits of output signals are 0 to 10 v for voltage based sensors and 4 to 20 mA for current-based sensors, these values should be scaled to represent ...
Hello friends, today's post as the name suggests is about how to send SMS with Arduino UNO and SIM900D using AT Commands. There are different types of SIM900D modules available in the market, so it doesn't matter which module you are using. All SIM900D modules work at AT commands basically so today I am going to show you how to send an SMS via AT commands without using any Arduino library. You should first read the AT commands manual which will give you an idea about AT commands. AT commands are special sets of commands which are used for communicating with SIM900 module. Using these AT commands we let our GSM work for us. Like if you want to send SMS then there's a specific AT command for sending the SMS similarly if you want to change the PIN co ...
Hello readers, I hope you all are doing great. In our previous tutorial, we discussed the implementation of pulse width modulation (PWM) in Raspberry Pi Pico using the MicroPyton programming example. We also implemented the LED brightness control program to demonstrate an application of the pulse width modulation technique.
In this tutorial, we are going to implement another application of pulse width modulation technique which is ‘Direction and position control of a servo motor’ with Raspberry Pi Pico module and MicroPython programming language.
Later in this tutorial, we will also discuss how to control the position of a servo motor with push buttons (to be used as control inputs) and also to use LEDs for indication purposes.
What is Servo Motor?
Before interfacing the servo motor with ...
Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss what is the Maximum Power Transfer Theorem. The power transferred from input to the output in electric circuitries is an important factor. If we have direct current circuitry then in this circuitry resistor will be taken as output. But if our circuitry is using alternating current then it will have impedance as an output.
In 1840 this theorem was given by the Moritz Von Jacobi (Jacobi was an engineer of Germany, most of his work was related to electrical machine and telegraphy), maximum power transfer theorem is also known as Jacobi's law. After the invention of this theorem had some confusion because some inventors thought that this theorem is also applicable to f ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show give you an overview of the future of Cloud Development. As one of the fastest-growing innovations of modern technology, cloud computing has revolutionized our relationship with the internet and the ways we’re able to connect and share resources with others around the globe. As tech companies are rapidly discovering even more ways to utilize all of the cloud’s advantages, the future of cloud development is sure to bring further advancements as an integral part of our everyday lives.
Where it is and where it’s going
Cloud development has taken off because of its ease of use, security, scalability, and reduction of costs. Many companies have been growing more relia ...
Hello friends, I hope you all are doing great. In today's tutorial, I am gonna show you How to Choose and Set Up a Business Phone System. Normally engineers like to be an entrepreneur and if you wanna start your own business then its essential to have a Business Phone Number. To maintain the success of your business, having a relevant and structured phone system will help your business grow. Here are the ways on how to choose and set up a business phone system.
Choosing Your Business Phone System
Before you can begin setting up, it is important that you take the time on choosing what type of phone system works for you. If you are starting a new or small business, every call you receive is important and could be the make or break to the success of y ...
Hello everyone, I hope you all are doing great. Today, I am going to share a new Heart Beat Sensor Library for Proteus. Using this Library, now you can easily simulate your Heart Beat Sensor in Proteus ISIS. I am quite excited while sharing this Library as it has never been designed before. All credit goes to the TEP team for creating this awesome Heart Beat Sensor Library for Proteus. You should also have a look at this Second Version of Heart Beat Sensor Library for Proteus.
Heart Beat Sensor is used to measure the Heart Beat Count of a person. When you are using a Heart Beat Sensor in hardware then there's a chance that you won't get the same results as this simulation because the placement of a finger on this sensor matters a lot. If you hav ...
Hello Everyone! Happy to see you around. In this post today, we’ll cover the 2SC2240 NPN Transistor. We will have a look at the 2SC2240 Datasheet, Pinout, Power Ratings, Equivalents & Applications.
Electrons are the majority charge carriers in this NPN transistor, in contrast to PNP transistors, where holes are the majority carriers. The 2SC2240 comes with a power dissipation of 0.3W, the amount of energy this transistor dissipates while operating in the forward-biased state, while the collector current is 0.1A means it can support load up to 0.1A.
This NPN transistor contains 3 terminals, named:EmitterCollectorBase
If the voltage at the base terminal is above 0.7V, the transistor will get forward-biased and the current will start flowing from Collector to Emitter terminal. If the ...
