That is just plain dumb...
A sensor is a device that detects a physical property and converts it into an electrical signal, such as temperature or pressure. A detector is a device that specifically detects the presence of something, such as a gas or a substance, without necessarily converting it into an electrical signal. In essence, a detector is a type of sensor that focuses on detecting a particular target or substance.
There are many types of stores that sell Valentine 1 radar detectors. One can purchase Valentine 1 products at Amazon, eBay, and various electronics stores.
Relative motion radar is a type of radar system that detects and tracks moving objects by measuring their relative motion compared to the radar system itself. It is commonly used in military and civilian applications for surveillance, navigation, and collision avoidance. The radar calculates the velocity of targets by analyzing the Doppler shift in the reflected signal.
Primary and secondary radar are commonly used in air traffic control. Primary radar detects the presence of aircraft by sending out radio waves and measuring the time it takes for the signal to bounce back. Secondary radar relies on transponders installed on aircraft to send out a signal that is received by the ground radar system, providing more detailed information about the aircraft's identity and altitude.
The Uniden 800 radar detector should be able to pick up a police signal from 2 miles away, but there is never a guarantee. It also depends on the type of radar used by the police.
The ionization type smoke detector was invented in 1931 in Switzerland.
An easily found carbon monoxide detector
The type of nerve that detects pain is a naked nerve fiber. Other fibers that detect pressure, taste, etc have special endings.
A weather radar is a type of radar used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity.
A metal detector can detect all types of metal....depending on in what type of soil it is in.
A non coherent detector is a type of device that does not need a receiver carrier to be phase locked to a transmitter carrier. A coherent detector demodulates signals.
