  • An oxygen sensor, is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed.cientists use oxygen sensors to measure respiration or production of oxygen and use a different approach.
  • Warnings can be visual or audible. Increased warnings indicate potentially hazardous lane changes.
  • 1. Electromagnetic parking sensorsThese rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once detected the obstacle, if the vehicle momentarily stops on its approach, the sensor continues to give signal of presence of the obstacle. If the vehicle then resumes its manoeuvre the alarm signal becomes more and more impressive as the obstacle approaches. Electromagnetic parking sensors are often sold as not requiring any holes to be drilled offering a unique design that discretely mounts on the inner side of the bumper preserving the 'new factory look' of your vehicle2. Ultrasonic parking sensorsThe rest of this posting refers to ultrasonic parking sensors only.The ultrasonic sensors are currently available in several brands of cars, with a variety of brand names such as Parktronic and Parking Aid. Some systems are also available as additional upgrade kits for later installation.

  • baseballs, runners and tennis serves.After the returning waves are received, a signal with a frequency equal to this difference is created by mixing the received radio signal with a little of the transmitted signal. Just as two different musical notes played together create a beat note at the difference in frequency between them, so these two radio signals are mixed to create a "beat" signal (called a heterodyne) and an electrical circuit then measures this frequency using a digital counter and displays the number on a digital display as the object's speed.
  • consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field. If a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal, and this produces an alternating electric field of its own.Larger portable metal detectors are used by archaeologists and treasure hunters to locate metallic items, such as jewelry, coins, bullets, and other various artifacts buried shallowly underground.
  • Resistive countersA resistive counter is associated with an in-river structure, such as a Crump weir.[1] The resistivity of a fish is lower than that of water. So, as fish cross this barrier, they pass embedded electrodes, and the difference in resistivity disturbs the field established in the vicinity of the electrodes.Optical countersAn optical counter is also associated with an in-river structure. However, rather than pass electrodes, in an optical counter the fish interrupt some of a number of vertically arranged beams of light. The pattern of beam-breaks can be used to determine the size, profile, and direction of motion of the fish.The performance of optical counters has been determined by studies, under various conditions, to be greater than 90%. Optical counters can also distinguish the size of fish more accurately than other counter types and so are particularly useful where a mixture of species inhabit a river (for example rivers where salmon mix with sea trout).Hydroacoustic countersHydroacoustic counters operate using the principles of sonar. A fish is insonified by a sound source, and reflections from the fish are detected by an underwater microphone. The reflection occurs because of the sudden change in impedance to sound waves within the fish, particularly at the swimbladder (90% of the reflection).
  • -Rain sensor:A rain sensor or rain switch is a switching device activated by rainfall. There are two main applications for rain sensors. The first is a water conservation device connected to an automatic irrigation system that causes the system to shut down in the event of rainfall. The second is a device used to protect the interior of an automobile from rain and to support the automatic mode of windscreen wipers.

  • Motion detector:There are four types of sensors used in motion detectors spectrum:Passive infrared sensors (Passive)Senses body heat. No energy is emitted from the sensor.Ultrasonic (active)Sends out pulses of ultrasonic waves and measures the reflection off a moving object.Microwave (active)Sensor sends out microwave pulses and measures the reflection off a moving object. Similar to a police radar gun.Tomographic Detector (active)Senses disturbances to radio waves as they travel through an area surrounded by mesh network nodes. Has the ability to detect through walls and obstructions.
