A detector only signals the presence.
A sensor allows both signaling the presence and intensity of stimuli.

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.
The refrigerant itself acts as the medium that carries the gas to the sensor in a halide leak detector. When the refrigerant comes into contact with the halide gas, it picks up traces of the gas and carries them to the sensor for detection.
A DAD (diode array detector) uses an array of diodes to measure absorbance at multiple wavelengths simultaneously, providing spectral information. A PDA (photodiode array detector) is a type of DAD that specifically uses photodiodes for detection. Both detectors are commonly used in chromatography to detect and quantify analytes in a sample.
Sensitivity describes the smallest change an instrument can detect. Range describes the largest change an instrument can detect.
When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
Common sensors in a washing machine include water level sensor to detect water levels, temperature sensor to monitor water temperature, and load sensor to determine the weight of the laundry. Some models may also have sensors for measuring motor speed or detecting unbalanced loads.
