  • Sensor Sense: Passive Infrared-Motion Sensors
    being sensed. The most common object a PIR sensor detects is the human body, so these sensors find use in automatic light switches, alarm systems, and door openers. Any object with a temperature above absolute zero emits infrared energy through black-body radiation. This energy is invisible
  • Sensor Could Detect Concealed Weapons Without X-Rays
    machines or radar instruments, the sensor doesn't have to generate a signal to detect objects - it spots them based on how brightly they reflect the natural radiation that is all around us every day. There is always a certain amount of radiation - light, heat, and even microwaves - in the environment
  • Wireless Sensor Network Aids Travelers in Parking Their Cars and Trucks
    Wireless Sensor Network Finds Parking Spots Users of a UCLA parking garage just check their cell phones for updates on vacancies. * Microprocessors within the sensors determine the type of sensed event, and whether to update the mainframe database. * Wireless sensors transmit data only on a valid
  • Polyimide 1, designers 0
    for monitoring radiation. Manufacturing the sensor required encapsulating various radiation-sensitive materials in an adhesive that could be silk-screen printed onto flexible, thin-film substrates. The radiation-sensitive materials were thermoluminescent (TLD) phosphors that when heated from between 120
  • Power Management Case Study
    power short range wireless sensor networks), optimal utilization of battery power will result in the longevity of the sensor nodes. The utility of sensor nodes in typical sensing tasks such as temperature, light, vibration, sound, radiation, etc. is phenomenal and collection of real-time data
  • Recent Design Updates and Selection Considerations for High Temperature and Cryogenic Aerospace Sensors
    . The same sensor might be required to withstand radiation and be used in monitoring vibration inside a nuclear power plant or on a space vehicle, or the cryogenic conditions of liquid propellants. These environments present a multitude of measurement challenges. Materials and construction must
  • Measurement and Control Basics, Fourth Edition
    of control loops was added to Chapter 2. Chapter 3 includes a more complete discussion of electrical and electronic. fundamentals needed in process control and instrumentation. The discussion of the basic principles underlying pressure measurement. has been expanded to include a discussion of sensor
  • Microwaves To Reveal Ocean Weather, Locate Land Mines
