Hi friends! Welcome to another article in which we are highlighting the basic details of a gas sensor from the MQ sensor series. Today, our focus is on the MQ136 hydrogen sulfide gas sensor that instantly detects the presence of the sulfide gas and sends the signals through digital and analog pins to the output devices for timely indication.
Our mission is to understand the basic introduction of this sensor, so we’ll go through it and see the main points of its datasheet, such as its features and specifications. After that, we'll move towards the working principle and physical dimensions of MQ136, and consequently, there will be a discussion of the basic applications where this sensor is widely used. I am sure it is going to be a useful study for you, so let’s get started.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you detailed discussion on Introduction to LM2904. LM 2904 consists of two builtin amplifiers. These amplifiers have high gain and they are internally frequency compensated. These amplifiers are designed for the operation from a single power supply for a large range of voltages. We can also operate them from multiply power supplies as well.
LM-2904 operates on 3.3V power supply, it is the most common power supply in digital systems. LM 2904 is also available in small sizes i.e. they are available in the latest technology DSBGA. LM-2904 has a lot unique features in comparison to the other standard amplifiers. These features include large DC voltage ga ...
Hello friends. We hope you are doing fine. Today we are back with another interesting project. It is based on the image processing technology. Developing efficient and cost-effective solutions for real-time applications is becoming increasingly important in the area of embedded systems and computer vision. This project makes full use of ESP32-CAM. ESP32-CAM is a compact and AI-enabled microcontroller with built-in Wi-Fi capabilities. We will create a real-time face detection and counting system.The ESP32-CAM serves as the core of the system. It captures high-resolution images at 800x600 resolution and hosts an HTTP server to serve individual JPEG images over a local network. The device’s efficient JPEG compression and network capabilities ensure minimal latency while maintaining high-quali ...

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 geeks, welcome to our new project. In this project, we are going to make a very interesting project which is an Up-Down counter. Most of us who have an electronics background or studied digital electronics must know the counter. Counter is a simple device which counts numbers. As per the digital electronics, there are two types of counter, the Up counter which counts in increasing order and another is Down counter which counts in decreasing order. And every counter has a reset limit, on which the counter resets to its initial value and starts the counting again. The limit of every counter depends on the bits of counter. For example, we have a 8 bit Up counter which means it will count upto 255 and afterwards it will reset and will start agai ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to DS18B20. DS18B20 is a temperature sensor that can measure temperature from -55oC to +125oC with an accuracy of +- 5%. It follows 1 wire protocol which has revolutionized the digital world. Because of its 1 wire protocol, you can control multiple sensors from a single pin of Microcontroller.
DS18B20 is normally used in industrial projects where high accuracy is necessary. I will give you a detailed overview of this temperature sensor in today's post where we will have a look at its Pinout, working, protocol, etc. I will also share some links to projects where I have interfaced it with Arduino or other microcontrollers. If you have any questions, please ask in comment ...
Virtual training platforms play a significant role in professional development, onboarding, and education across all types of organizations. These solutions are designed to facilitate live instruction, interactive sessions, group activities, and self-paced learning in remote settings. Several platforms offer specialized features for managing participants, tracking engagement, and supporting various instructional methods. Differences in integration options, accessibility, scalability, and engagement tools can influence how each platform is used within a training program. Webex Training Center represents one approach to online learning, while other platforms offer alternative workflows and features tailored to diverse training needs.

Hello friends, I hope you all are doing great. In today’s tutorial, we will discuss What are Sound Transducers. The transducer is a module used for the transformation of energy from one type to other types of energy. For instance, the loudspeaker converts the electrical signal into the sound. Transducers are mostly used in automation (It is a technology that used for a different process where most work is done with less manpower), measuring devices, and for the conversion of the electrical energy into the different physical parameters like force, sound, light, etc.
In today's we will have a look at sound transducer's working, construction, applications and other related terms. So let's get started with What is Sound Transducers.
What are Sound Tra ...

We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.
