Nanosensor : Block Diagram, Working, Interfacing & Its Applications

September 16, 2022 By WatElectronics

Nanosensor

In nanotechnology, the nanosensor is used as a sensing device to measure/detect/sense the chemical and physical properties of matter or nanoparticles at the nanoscale of less than 100 nm. These are used for changing the applications and properties of the materials. These are nanodevices that observe physical quantities and convert them into signals that can be detected and analyzed. Nanosensors are used in medicine, pollution control, pathogen detection, and process monitoring in … [Read more...]

What is Magnetic Sensor : Types, Working & Its Applications

August 13, 2022 By WatElectronics

Magnetic Sensor

Magnetic sensors are the sensors that convert the change/ magnitude of a magnetic field into an electrical signal. The Earth's magnetic field or the magnetic field referred to as magnetism, is a well-known but invisible phenomenon. Magnetic sensors convert invisible magnetic fields into electrical signals and help to have visible effects. They were designed decades ago as a sensor using the electromagnetic induction effect and has expanded into applications in the magneto-resistance effect, … [Read more...]

Interfacing Knock Sensor to a Microcontroller or Arduino

August 9, 2022 By WatElectronics

Knock Sensor Interfacing Working

Generally, automobiles (especially 2-wheeler and 4-wheeler vehicles) and security monitoring systems are equipped with multiple sensors that constantly monitor their operation and condition. Some sensors measure air, oxygen, and temperature, while others, such as knock sensors, measure vibration and noise levels in the vehicle's engine and security monitor systems. Knock sensors, on the other hand, have a much wider range of applications and are also known as piezoelectric sensors Or vibration … [Read more...]

Knock Sensor : Circuit, Working, Testing, Types, Failure Causes & Its Applications

July 22, 2022 By WatElectronics

Knock Sensor Diagram

In automobiles, engine knocking is a sound or detonation or engine ping that occurred due to high-frequency vibrations caused by poor quality fuel, wrong spark plug, irregular ignition /explosion occurring in the cylinder, and deposits on the cylinder wall. These engine knocks can cause power wastage of the engine and destroy the engine. These days, modern vehicles are equipped with various sensors to monitor their functioning like measuring the air, temperature, etc. In addition to these, the … [Read more...]

What is Transistor-Transistor Logic : Working & Its Applications

July 16, 2022 By WatElectronics

Transistor Transistor Logic

In 1963, Sylvania as Sylvania Universal High-Level Logic (SUHL) introduced the first Transistor-Transistor Logic circuits. The concept of TTL was developed to achieve high speed, low power dissipation that allows optimization of the design. It belongs to the digital logic family and is designed with bipolar transistors, resistors, and diodes. It is widely used in various applications such as electronic devices, computer control systems, industrial controlling systems, the design and fabrication … [Read more...]

What is Class D Amplifier : Working, Types, Characteristics & Benefits

July 2, 2022 By WatElectronics

Block Diagram

The initial invention of the class D amplifier took place in the year 1950 by Alec Reeves, but the device was actually called by the name class D in 1955. The first IC-based class D amplifier was introduced by Tripath in the year 1996 and this version was widespread across various domains. The need for class D amplifiers such as minimal power dissipation when compared with other topologies like class A, class AB and class B allowed class D to use in multiple applications. Also, minimal circuit … [Read more...]

What is DMA Controller : Working & Its Applications

June 20, 2022 By WatElectronics

DMA Controller in Computer

To execute any operation in a computer system, first, the microprocessor gets the instruction, decodes it, and further, executes. However, if the microprocessor is executing the entire task individually within the system, then it keeps the microprocessor busy continually. Therefore, to improve the processor’s performance, an external device like a DMA controller is utilized to control the operation of data transfer between memory & peripherals with the least utilization of CPU. Basically, … [Read more...]

What is Low Noise Amplifier : Working, Types, Design & Its Applications

June 10, 2022 By WatElectronics

Low Noise Amplifier

In a communication system, a low noise amplifier or LNA is an essential component in the receiver section. The main role of this amplifier is to amplify the weak signal by keeping the noise as small as possible. The performance of this amplifier can be measured most particularly by considering different factors like its noise figure, gain, dynamic range, matching, stability, and return loss. These amplifiers play a key role in millimeter-wave applications like passive remote sensing, Earth … [Read more...]
