Magnetic Sensors

Recently the US Military has developed a special set of sensors for water supplies for troops. Any time a base camp is set up it is important to monitor the water supplies and test them. You cannot simply test them when you arrive you need constant monitoring so that insurgents or enemies do not pollute [...]

Data collection using modern data logging systems is revolutionizing the face of school science labs around the world. Information that was previously tedious to collect, subject to much guess work and often difficult for many students to visualize or draw any actual learning value from, can now be displayed in a clear, graphical and easy [...]

To understand clearly how the interactive white boards might be able to improve the teaching environment, you need to understand the sensing technologies which are used to track the interaction on the screen surface. These are resistive, laser, infrared optical, camera based optical and ultra sonic. Among all these technologies, the most successful in commercial [...]
