A detector only signals the presence. A sensor allows both signaling the presence and intensity of stimuli.
Stimuli is the part of a plant.if we touch leaves of mimosa
it detects: Heat and Cold.some other stimuli the skin detects are: Roughness, smoothness, and pain.

Somatic sensory division...
Emotions are neural signals that tell the brain about the world around us. These signals tell the brain how to respond to the stimuli.
Receptors
stimuli are converted into electronic signals. Such electronic signals travel by a huge network of nerves throughout the body. These signals converge to the brain, where sensory neurons interpret them and send back an "order" through the Central Nervous System, to the correspondent point of the body where the stimulus has happened. Such "order" may refer to the release of defence cells, or simply tell your arm to touch the point of the stimulus,in order to calm you down, as a simple example. The signal that flows through the nerve, uses a mineral, magnesium, as a basis to conduct the electronic signal. Sodium is another mineral that participates of the process. Such travel may take only miliseconds to reach the brain and to come back.

The chemical stimuli in the body are converted into electrical impulses when some sensory input system in the body is triggered. This can be a visual sense like the eyes, or a aural sense like the ears. The chemical stimuli gets converted into potential energy and converted.
chemical signals of the endocrine system, the group of glands that, along with the nervous system, controls the body's responses to internal and external stimuli. Hormones are carried to their target cells in the bloodstream.
The gates on the ion channel may open or close to three kinds of stimuli: 1. Stretching of the cell membrane 2. electrical signals 3. Chemicals in the cytosol or external environment
