Design specifications for an embedded system are crucial for ensuring the successful development and deployment of the system. Here’s an explanation of each point based on the some factors: Processor Power: The processor power of an embedded system is a critical specification that directly influences its computational capabilities. It involves selecting a suitable central processing […]
Earthing: An Essential Component of Electrical Safety Electricity is one of the most significant discoveries in human history, and it powers most of our modern-day gadgets and technology. However, as beneficial as electricity is, it can also be incredibly dangerous, causing electrical shocks, fires, and even fatalities. That is why proper electrical safety measures, such
X-Y recorders or X-Y plotters accept two inputs and create a chart or graph of one input versus the other. They are commonly used to determine the relationship between the two inputs. It is one of the types of recording and indicating instrument. Let’s see what is recorder? and classification of recorders first. Introduction to
Thermistors (construction of thermal resistor) are semiconductors which behave as resistors with a high negative temperature coefficient of resistance. Thermistor word derived from Thermal resistor. It became available in early 1960’s. They are based on oxides of semiconductors which has high temperature coefficients (mostly NTC) and have high resistance. Construction of Thermistor Thermistors are composed
Instrumentation a collective term for measuring instruments that are used for indicating, measuring and recording physical quantities. The term has its origins in the art and science of scientific instrument-making. Electronics for You bring you some topics on basics of Instrumentation Engineering. Click on the link for blogs on Instrumentation. It focuses mainly on two units Transducers and Sensors
Sensors and transducers are crucial in instrumenting an engineering system. Sensors may be used in an engineering system for a variety of purposes. A measuring device passes through two main stages while measuring a signal. First, the measurand is felt or sensed by the sensing element. Then, the sensed signal is transduced (or converted) into
When two metals having different work functions are placed together, a voltage is generated at the junction which is nearly proportional to the temperature. This junction is called a thermocouple. Working Principle of Thermocouple Thomas Seebeck discovered in 1821 that when two dissimilar metals were in contact, a voltage was generated where the voltage was
Resistance temperature detectors, or resistance thermometers, employ a sensitive element of extremely pure platinum, copper or nickel wire that provides a definite resistance value at each temperature within its range. Thermoresistive Effect The relationship between temperature and resistance of conductors in the temperature range near 0°C can be calculated from the equation where Rt =

Semiconductor-based light sensors as well as light sources are needed in optoelectronics. A light sensor is also known as a photodetector or photosensor. It is a device that is sensitive to light. Some photosensors can serve as energy sources (cells) as well. A photosensor may be an integral component of an optoisolator or other optically
The various photoelectric transducers that convert light energy into electrical energy are Photoemissive transducer, Photovoltaic transducer, Photoconductive transducer. Photoemissive Transducers The properties of a photoemissive cell or phototube are used in photoelectric transducers. The vacuum photoelectric cell consists of a curved sheet of thin metal with its concave surface coated with a photoemissive material, which
