In everyone’s life, water is a basic need but conserving water as well as its proper maintenance is very important. So here is a rain sensor to detect the rain in the agriculture field & generates an alarm whenever there is rain so that we can take some proper actions to conserve the water as well as crops. Consequently, we can enhance the underground water levels through a recharge technique used underwater. This sensor detects the rain and gives an alert to concerned persons in d … [Read more...]
What is a Clap Switch : Circuit & Its Working
As the name suggests, clap switch is a simple interesting project for beginners and hobbyists. This circuit is used to make the light ON through a clap sound but it can work through any kind of same pitch sound. The essential components used to build this project are electric condenser mic as a sound sensor. The main function of this device is to change the energy of sound to electrical. A 555 timer through a transistor activates the LED and after some time, it will be turned OFF. When this … [Read more...]
What is LCD 16X2 : Pin Configuration & Its Working
In LCD 16x2, the term LCD stands for Liquid Crystal Display that uses a plane panel display technology, used in screens of computer monitors & TVs, smartphones, tablets, mobile devices, etc. Both the displays like LCD & CRTs look the same but their operation is different. Instead of electrons diffraction at a glass display, a liquid crystal display has a backlight that provides light to each pixel that is arranged in a rectangular network. Every pixel includes a blue, red, green … [Read more...]
What is an Ideal Diode : Working & Its Characteristics
An ideal diode is one kind of electronic component that includes two terminals and allows the flow of current in only one direction because it has less zero resistance in one way and infinite resistance in another way. The most frequently used type of diode is a semiconductor diode. It is a crystalline part of semiconductor material that includes a PN junction and it is connected to two electrical terminals. The first semiconductor electronic devices are semiconductor diodes. At present, most … [Read more...]
What are Electronic Circuit Symbols – Reference Designators
There are different kinds of electronic components that are used in different circuits to make different engineering projects as well as electronic devices. These components are represented with electronic circuit symbols within various circuits. At present, circuit symbols & their utilization have been very much standardized. This allows the user to identify the components like wires, semiconductors, batteries, logic circuits, ICs, etc. By using electronic component symbols in circuits, … [Read more...]

What is IMPATT Diode : Construction & Its Working
The concept of IMPATT diode was actually invented in the year 1954 by William Shockley. So, he expanded the idea for producing a negative resistance with the help of a mechanism like transit time delay. He proposed the injection technique for charge carriers within a PN junction is forward biased and published his thought in the Technical Journal of Bell Systems in 1954 and titled with the name 'Negative Resistance Occurring from Transit Time within Semiconductor Diodes. Further, the proposal … [Read more...]
What is PIN Diode : Construction, Working & Its Applications
We know that there are different types of diodes are used in different applications based on the requirement like Varactor diode, Schottky diode, LED, Zener diode, etc. Even though, the most popular diode including a basic PN- junction is also used in different circuits which are called a PIN diode. As compared with a normal PN junction diode, this kind of diode is different because this diode includes three layers like P, I & N whereas the PN junction diode includes two layers like P & … [Read more...]
What is Multimeter : Types, Working & Its Applications
A measuring device like a multimeter is an essential device in the field of electronics and electrical labs or workshops to measure the electrical properties of industrial wiring as well as tools. Before knowing about this device, some fundamental concepts we have to know like the voltage, current, and resistance. Here, voltage is the disparity in charge between the two points, the current is nothing but the flow of charge carriers and resistance is the measure of the current flow. At … [Read more...]
What is IR Sensor : Circuit & Its Working
IR technology is used in a wide range of wireless applications which includes remote controls and sensing. The infrared part in the electromagnetic spectrum can be separated into three main regions: near IR, mid-IR & far IR. The wavelengths of these three regions vary based on the application. For the near IR region, the wavelength ranges from 700 nm- 1400 nm, the wavelength of the mid-IR region ranges from 1400 nm - 3000 nm & finally for the far IR region, the wavelength ranges from … [Read more...]
