Electronic Component: Infrared Sensor
http://electro-component.blogspot.com/2009/10/infrared-sensor.html
Monday, October 26, 2009. Sensors are everywhere, some examples:. Smaller shops or barbershops, often have a beam of light crossing the room near the door, which ends up in a photo-sensor on the other side of the room. When a customer breaks that beam, the bell rings. Same thing with ultrasonic sound waves used by bats for example, they bounce back off a target and create an image. These are what we call active sensors. They send out energy, and detect changes in them . My articles will be around the tec...

Electronic Component: Resistors
http://electro-component.blogspot.com/2008/07/resistors-resistors-are-components-that.html
Thursday, July 24, 2008. Resistors are components that just about every electronic device uses. A resistor is a component that resists the flow of current. They do this by either extending the length of wire that the electricity must flow through or forcing the current to pass through a poor conductor, such as carbon. It can protect components that have a specific current rating. It can change the function of the circuit. It can create a "dummy load" for a circuit in order for testing purposes. The "dumm...

Electronic Component: April 2009
http://electro-component.blogspot.com/2009_04_01_archive.html
Wednesday, April 8, 2009. Optoisolators are circuits designed to isolate one circuit from another using light. Why would you use light instead of implementing some diodes or voltage regulators? Because light is essentially a guaranteed protection. If an overvoltage or overcurrent is applied to the optoisolator, the optoisolator circuit is destroyed and the circuit(s) it was protecting will not be affected. Posted by Dadang Supriatna.

Electronic Component: November 2008
http://electro-component.blogspot.com/2008_11_01_archive.html
Thursday, November 6, 2008. Capacitors are among the most commonly used components in electronics. Their construction is fairly simple, two metal plates and a dielectric layer separating them. Capacitors are very similar to batteries since they store electrical charge. However, capacitors must be charged with electricity, unlike batteries which produce their own using chemicals. Capacitors are also used to make DC voltage constant. In power supplies, the voltage can vary. With a capacitor include...Capac...

Monday, October 26, 2009. Speed Sensors of Turbine. With turbine technology finding its way into more and more aspects of todays high tech world, many people just like yourself may find themselves in uncharted water in having to deal with them. The fact is, that turbines can be simple or extremely complex depending on what they are used in. A Simple Turbine Engine. Turbo Charged Air Intake Systems. Also, a turbine can be an integral part but not the main component of a propulsion system or engine. A ...
