“Radiant” heat relates to one of three of the most prevalent means that heat is transferred. Radiant heat is long wave infrared energy radiated from any “hot body” to any “cooler body” within sight. In other words if you’re in the sun you’ll feel warmer than if you’re in the shade. If you can see [...]

all about electronic cigarette
An electronic cigarette, e-cigarette or personal vaporizer, is a battery-powered device that provides inhaled doses of nicotine by way of a vaporized solution. It is an alternative to smoked tobacco products, such as cigarettes, cigars, or pipes. In addition to purported nicotine delivery, this vapor also provides a flavor and physical sensation similar to that [...]

electricity
ELECTRICITY has been called the stuff of the universe. Early scientists believed it was a kind of fluid that flowed through wires, that it was of two kinds, and that it was contained in equal amounts in neutral bodies. Now it is known as a movement of electrons — a negatively-charged body indicating an excess [...]

Mechanical Magnetic Compasses Sensor
The first recorded use of a magnetic compass was in 2634 B.C., when the Chinese suspended a piece of naturally occurring magnetite from a silk thread and used it to guide a chariot over land [Carter, 1966]. Much controversy surrounds the debate over whether the Chinese or the Europeans first adapted the compass for marine [...]

Radio-frequency identification (RFID) is
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. Utilizing radio frequency waves, an RFID tag can be applied to or incorporated into a product for the purpose of location and identification. UHF Passive RFID can be read from several meters away [...]

Analog to Digital Converter : ADC MAX 154/158
Maxim ADC issued a new generation, ie MAX154 ADC which has a 4-channel input with a resolution of 8 bits, while the MAX 158 has 8 channels with a resolution of 8 bits. This chip is very compact because it is an internal pulse source, compare with ADC0808 which requires an external pulse source using [...]

Parking Sensors on The Car
Parking sensor (sensor backwards) is an electronic device mounted on the rear of the vehicle that detects the rear of the vehicle so that it can stop the vehicle before touching / hitting parts that are not visible from the cabin of the vehicle. This sensor is standard equipment on luxury cars, but now many [...]

Geomagnetic Sensors (compass) for an autonomous platform
Vehicle heading is the most significant of the navigation parameters (x, y, and O) in terms of its influence on accumulated dead-reckoning errors. For this reason, sensors which provide a measure of absolute heading or relative angular velocity are extremely important in solving the real world navigation needs of an autonomous platform. The most commonly [...]

RFID (Radio Frequency Identification)
Radio-frequency identification (RFID) is a technology that uses communication via electromagnetic waves to exchange data between a terminal and an electronic tag attached to an object, for the purpose of identification and tracking. Some tags can be read from several meters away and beyond the line of sight of the reader. Radio-frequency identification involves interrogators [...]

How Oxygen sensor work
Priciple of operation : When voltage is applied to a zirconia electrolyte cell, oxygen is pumped trought the zirconia disc from the cathode side to the anode side because the carriers of the current flowing trhought the zirconia electrolyte is oxygen ion. By attaching a cap with a pinhole on the cathode side of the [...]
