Hello Friends, I hope you all are fine and will be doing well in your life. In today's tutorial, I am going to give you a detailed Introduction to DHT11. It is an embedded sensor used to measure temperature & humidity in the surroundings and gives calibrated digital output. It can measure temperature in the range of 0°C to 50°C with ±2°C accuracy. Its humidity range is from 20% to 80% with ±5% accuracy. It is a small, low cost and easy-to-interface embedded sensor.
In this tutorial, I will explain its working, pinout, protocol and interfacing with other microcontrollers in detail.
Here are a few important features of DHT11, given in the below table:

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to BC337.
BC337 is a general-purpose transistor mainly used for lower power audio amplification and switching purposes. It belongs to the NPN transistor family and comes with a maximum gain of 630. The continuous collector current is 800mA indicating it can drive loads under 800mA.
I’ll be discussing the complete introduction to BC337 in this post covering pinout, working, power ratings, alternatives, applications, and physical dimensions of BC337.
Stay tuned.

Update: We have created a new version of this library, which you can check here: Arduino Pro Mini Library for Proteus V2.0.
Hello friends, hope you all are fine and having fun with your lives. In today's post, I am gonna share Arduino Pro Mini Library for Proteus. Recently, I have shared Arduino Nano Library for Proteus, and before that I have also posted Arduino UNO Library for Proteus as well as Arduino Mega 2560 Library for Proteus, and now I am gonna share Arduino Pro Mini Library for Proteus. Arduino Pro Mini is another Arduino board which also uses the same Atmega328 Microcontroller and has almost the same number of pins as Arduino UNO and Arduino Nano. Arduino Pro Mini is even more smaller than Arduino Nano board. It doesn't have the pro ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP122. It is a Darlington braces NPN transistor. It works like an ordinary NPN transistor, but as it consists of a Darlington pair it has a decent collector current assessment of nearby 5 amperes and it's gain is around 1000. This transistor can bear 100 volts around collector and emitter terminals due to this feature it can be used for high loads.
This is a common purpose transistor it used in different industrial projects. It manufactured for less time taking switching submissions. In today’s post, we will have a look at its protection, wreck, distinction, entitlements, etc. I will also share some links where I have connecte ...
Abstract: This paper is written to represent a web-server based real-time weather monitoring system implemented using the ESP32 module. The system is designed to measure the weather conditions like temperature, pressure, humidity etc, in its vicinity. This system continuously provides real-time data (weather conditions) over limited or controlled areas, for example, agriculture fields, homes or a particular room, industries etc. Although we have satellites for weather monitoring but to perform research over a particular area, the data observed should be highly accurate which is not possible with satellites. To implement an IoT network we need to use a webserver to continuously store and display the real-time data which can be accessed globally. ’T ...
Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Hi Guys! Hope this finds you well. I welcome you on board. Thank you for clicking this read. In this post today, I’ll be explaining the Introduction to BC559.
BC559 is a bipolar junction transistor used to drive loads under 100mA. It falls under the family of PNP transistors and is mainly known as a current-controlled device. Where small current at one terminal is used to drive large current change at the remaining two terminals.
Read this post all the way through, as I’ll be touching pinout, working, datasheet, physical dimensions, power ratings, and applications of a BC559 transistor.
Let’s get started.

Hi Guys! Glad to see you around. I welcome you on board. In this post today, I’ll walk through the Introduction to LM2575.
LM2575 is a step-down voltage regulator mainly used to step down the voltage. It is also known as a buck converter and is used to drive load under 1A. In the customized output version of the buck converter, you can set the output voltage as you like better. It comes with an extremely good load and line regulation and is available in fixed output voltages with 3.3V, 5V, and 12V.
I suggest you read this post all the way through, as in this post I’ll detail the Introduction to LM2575 covering the datasheet, pinout, features, and applications of this component LM2575.

The Internet of Things (IoT) and the Industry 4.0. Distinct technological revolutions but with a common goal: To integrate equipment (digital or analog) to a computer network.
And to be part of this revolution, the developer goes out of its way to include wired ethernet modules or WIFI modules in its circuits. Which increases complexity, circuit size and development cost.
What if I told you that already has a built-in WIFI microcontroller? And that it fits in the palm of your hand? For just 1 US dollar?
Today I’m going to introduce you to the ESP8266 microcontroller, from Espressif. And for those of you who already program in 8Bit microcontrollers like the Atmega328 (one of the most common on Arduino) and struggle to build your code in the modic SR ...
