What is a hall effect sensor? Its a sensor simply by using hall effects principle to operate it.. Hey get to the point.. allright..

A hall effect principle is simply having electrical current flowing through a conductive material which is immersed in a magnetic field. The applications of hall effect sensor can be found widely in brushless DC motor, flow sensor, tachometer. To understand brushless DC motor just look at your desktop PC’s cooling fan.

If you try to open it up you’ll find that it has no brush or contacts to run the motor but what runs it is the Hall Effect sensor by giving the circuit board electrictrical pulse to alternately suplly current to generate electromagnetic field in order to rotate the motor.

Its a battle between coorporations and companies to produce the most humanoid robots. We are heading towards a world of automation and AI (artificial Intelligince). The are watching too much of Terminator, I-Robot, The Matrix.. In these movies it shows that robots takes over human task and decides for us in the future. and I might say the nEaR future. At that stage we will strugle for survival from the menace of these robots. Its always a drawback to give birth of intelligence to something that might retaliate back at us. But anyway its human’s nature to create, invent and innovate for the better of our lives.

Juz imagine if one day when you r about to refuel your car at gas station and what you’ll see is hydrogen filling station. and could sumtimes be water.

and you’ll say: what the *%^&^*?

while I’d say : welcome to the hydrogen age.

Fuel Cell technology is a system that converts the flow hydrogen and oxygen into usefull electrical energy. However there are many types of of cell though. The electrial power is used to drive the high torque electrical motor that will be able to run a car at a satisfying speed.Nevertheless it is environmental friendly system.. Its a ZEV (zero emmission vehicle) system which only produces water vapor and heat as its byproduct.

While being a renewable energy source it stills a big contender to petrol fuel which dominates vehicle fueling market. but why since fuel cell is far more better off than petrol in many envoronmental aspects but petrol is still a predominent commodity? this is due to the establishment of internal combustion that consumes on petrol for the past 141 years since Nikolaus August Otto, and the rest are great investment which makes tonnes of money per week.

The fuel cell offers a very promising future of super clean and efficient energy. As we know our planet is degrading due to the enourmous green house gases being release everyday mainly from vehicle, factories, power plant and etc. are all contributing factor to global warming which eventually disrupts the global climate at causes undesirable global mass disaster weather chaos. from ultimate drought to extremely hostile blizzard storm.

Today scientist and engineers are pushing the limit juz to tackle existing and potential menance to the planet which air pollution that affects global climate in total.

Thats the reason FUEL CELL are being born.. WELCOME TO THE HYDROGEN AGE

thanks to Sir William Robert Grove 1839 that pave the way for todays modern fuel cell.
