Yes, a detector can identify the presence of drugs using various methods, such as chemical analysis, spectroscopy, or electronic sensors. These detectors can be designed to recognize specific substances based on their unique chemical signatures. Common applications include law enforcement drug testing, airport security screenings, and medical diagnostics. However, the effectiveness and specificity of a detector depend on its design and the technology used.
A metal detector can detect all types of metal....depending on in what type of soil it is in.
the function of a diode detector is to detect stuff

With a ultraviolet light detector.
-- If the detector is designed to detect wave characteristics, then light exhibits all the characteristics and behavior of a wave when it encounters that detector. -- If the detector is designed to detect particle characteristics, then light exhibits all the characteristics and behavior of a particle when it encounters that detector.
motion detector
detect nytrogen
I detect decay
By not carrying anything that it will detect, of course.
A photoelectric smoke detector uses a light sensor and a light source to detect smoke particles in the air. When smoke enters the detector, it scatters the light, triggering the alarm.
It is possible for an alcohol detector to detect alcohol in lotion, depending on the sensitivity of the detector and the amount of alcohol present in the lotion. Some alcohol detectors are able to detect a wide range of alcohol compounds, including those found in lotions.
