Lightning detectors and weather radar work together to detect storms. Lightning detectors indicate electrical activity, while weather radar indicates precipitation. Both phenomena are associated with thunderstorms and can help indicate storm strength. Air is moving upward due to instability.
R8 Radar/Laser Detector. The R8 is Uniden's top-of-the-line offering. It can identify threats coming from all four directions thanks to its dual antenna, and you get notified via voice alerts.
Many automated airport weather stations within the United States use the National Lightning Detection Network (NLDN) to detect lightning via the automatic lightning detection and reporting system (ALDARS). The NLDN uses 106 sensors nationwide to triangulate lightning strikes. Data from the detection grid is fed into ALDARS, which in turn sends ...
A Perry Weather lightning warning system. The detection equipment is designed to constantly survey atmospheric electrical activity and potential for lightning occurrence via radar and other methods. [citation needed] Storms are scanned by radar to determine the degree of electrification and potential for lightning occurrence. [citation needed]
DFR7. This low-cost detector has impressive range and all the requisite features, including GPS for low-speed false-alert muting, manual marking of up to 100 known radar locations, and speed ...
Electric eye for a garage door opener. An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam.
An early radar detector Car radar detector (Japanese) A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding.
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
