In safety equipment, flame sensors, fire alarms, and smoke sensors play a major role because these sensors assist us in maintaining our offices, homes, or stores very safe from fire accidents. Generally, safety equipment is used in almost all apartments, modern homes, cinema halls, offices, and shopping malls, and in some regions, it is compulsory to fire security devices. To overcome this problem, a flame sensor is used to protect all these from fires or flames. This article discusses an … [Read more...]

Fingerprints of humans are practically unique that’s why these are very successful in recognizing individuals. Fingerprints of individuals are collected & maintained by law enforcement agencies and also other occupations for certification or professional licensing like stockbrokers, financial advisors, teachers, real estate agents, security, doctors or nurses, contractors, and many more. At present, advancements in technologies use these scanners as an additional security feature. So these … [Read more...]

The thermocouple was first designed after the examination of the thermoelectric phenomenon in the year 1821 by Thomas Johann Seebeck. He observed a circuit that contains two wires made with two different metals like platinum or bismuth & antimony which are connected jointly at their ends. So heating one of the junctions will produce a weak electric signal that is simply proportional to the variation in temperature among the two welds. So this type of arrangement is known as a thermocouple. … [Read more...]

Measuring current within any system without affecting its performance is significant. So, current measurement is very essential in many instrumentation and power systems. Usually, current sensing was mainly for protection & control of the circuit. But, with the progress in technology, sensing current has appeared as a technique to examine and improve performance. So knowing the sum of current being transmitted to the load is very helpful for an extensive variety of applications. So this … [Read more...]

In automobiles, there are various sensors to control all engine functions and work to indicate failures and protect the vehicles from damage. Air Flow Sensor or Mass Air Flow (MAF) sensor is one detection device, which can convert the amount of air entering the vehicle's engine into a voltage signal to calculate the load of the engine. This sensor is necessary to determine the amount of fuel injection, when to fire the cylinders, shifting of gears, and calculate the exact air-fuel ratio/flow … [Read more...]
