Occupancy sensor An occupancy sensor is a lighting control device that detects occupancy of a space by people and turns the lights on or off automatically, using infrared, ultrasonic or microwave technology. Occupancy sensors are typically used to save energy, provide automatic control, and comply with building codes. Three basics types of occupancy sensors are: 1  Passive infrared sensor, which works on heat movement detection.

Principles of Motion Sensing Principles of Motion Sensing. Sensors able to detect three-dimensional motion have been commercially available for several decades and have been used in automobiles, aircraft and ships. However, initial size, power consumption and price had prevented their mass adoption in consumer electronics. While there are other kinds of motion detector technologies available commercially, there are four principle types of motion sensors which are important for motion processing in the consumer electronics market.

Are Microwaves Really a Health Hazard? Microwaves are a type of electromagnetic wave (shocker, right?), just like UV rays and radio waves. Instead of cooking food with heat like a conventional oven, microwave ovens excite atoms (or get 'em all moving around), cooking food evenly throughout rather than from the outside in (like an oven does).

All About Robotic Surgery. The bottom two are called the ventricles. The heart's natural pacemaker is called the sinoatrial (SA) node or sinus node. It's a small mass of specialized cells in the heart's right atrium. It produces electrical impulses that make your heart beat. For your heart to beat properly, the signal must travel from the SA node down a

- NAMUR Inductive Proximity Sensors. WORKING PRINCIPLE. These sensors act as a variable resistor. With the active surface free, they have a low output resistance. In the presence of. a metal target the output resistance is high. The resulting variation in the current is used to control a signal amplifier. TECHNICAL CHARACTERISTICS.

- RADIO WAVES | MICROWAVES | INFRARED | VISIBLE LIGHT | ULTRAVIOLET | X-RAYS | GAMMA RAYS. Microwaves are good for transmitting information from one place to another because microwave energy can penetrate haze, light rain and snow, clouds, and smoke. Shorter microwaves are used in remote sensing. These microwaves are used for radar like the doppler radar used in weather forecasts.

How Microwave Cooking Works Microwaves. ­Not surprisingly, a m­icrowave oven uses microwaves to heat food. Microwaves are a type of wave that are sandwiched between radio waves and infrared radiation on the electromagnetic spectrum. In the case of microwave ovens, the commonly used wave frequency is roughly 2,450 megahertz (2.45 gigahertz). Waves in this frequency range have an interesting property: They're absorbed by water, fats and sugars. Once absorbed, they're converted directly into atomic motion -- heat.
