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 Pulse Sensor : Types & Its Applications
Knowing the heart rate data is very helpful while doing exercises, actively studying, etc. But measuring heart rate is a difficult problem. So, a pulse sensor is used to overcome this problem. This sensor is a plug & play heart-rate sensor, utilized by artists, students, athletes, mobile & game developers, makers who desire to know the existing heart-rate data to use in their live projects. This sensor merges a simple optical heart rate sensor through a circuit. This circuit is used … [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...]
What is a Temperature Sensor : Types & Its Applications
In our day-to-day life, we all utilize different types of sensors. From that, the temperature sensor is one kind of sensor that is used most frequently in different forms like microwaves, water heaters, refrigerators, thermometers, etc. Generally, these types of sensors are used in a wide range of applications to measure the amount of coolness or hotness of the device and change it into a readable unit. Do you know how the temperature of the buildings, dams, boreholes, soil are measured:? … [Read more...]
What is a Proximity Sensor : Types & Its Applications
Proximity sensor comprises all sensors that execute non-contact detection as compared to limit switches that notice objects through contacting physically them. These types of sensors change the data into an electrical signal on the movement or occurrence of a target. These sensors are used in mobile phones. Once the target is in a small range, then the lock screen of the mobile user interface will come into view which is called sleep mode. These sensors can be utilized to identify air gestures … [Read more...]
