Human Intelligence can collect information from a wide variety of sensory inputs, which are really more than the 5 basic senses, including:
Vision - Humans can perceive and interpret visual information through the eyes, including color, shape, depth, motion, and texture.
Hearing - Humans can perceive and interpret auditory information through the ears, including pitch, volume, tone, and spatial location.
Touch - Humans can perceive and interpret tactile information through the skin, including pressure, texture, and damage pain.
Taste - Humans can perceive and interpret gustatory information through the taste buds, including sweet, sour, salty, bitter, and umami.
Smell - Humans can perceive and interpret olfactory information through the nose, including various scents and odors, and toxic chemicals.
External Thermal - Humans can perceive and interpret infrared heat information through the skin from a distance without any tactile touch pressure.
External Pressure - Humans can perceive and interpret air/water pressure information through forces applied to the ear drums.
Vestibular Balance: Humans can perceive the spatial position and 3D orientation of the head in realtime.
Proprioception - Humans can perceive the spatial position and 3D orientation of the body in real time through very long neural connections throughout the body called nerves.
Internal Thermal - Humans can perceive the internal body temperature, and autonomously shutdown parts of the body if it becomes too low.
Blood CO2 concentration level - Humans can perceive the concentration of the CO2 level and use this to autonomously manage the Oxygen and CO2 concentrations in the blood.
Interoception - Humans can perceive their present level of key nutrients needed for fuelling the body, and water level as indicated by thirst.
Muscular Force - Humans can perceive the amount of tension stress being applied to muscles and tendons through very long neural connections throughout the body called nerves.
Extra sensory perception (maybe) – although obviously esoteric, extremely controversial, and heavily debated in scientific fields and with the general public, this arguably may be a genuine area of Human sensory ability. For example, based on partially classified research by scientists such as Dr Hal Puthoff and many others, it seems this type of sensory information does need to be considered for completeness. Particularly as this type of sensory information relates to what amounts to extremely poorly understood theories of consciousness, identity, communication, matter, and the true fabric and construction of the Universe.
So, in addition to the five commonly cited primary senses, there are several additional sources of sensory information that contribute to Human Intelligence including others that are not listed above. For example, some Humans can sense Magnetic fields and directionality, and some Radio Frequency emissions.
Every Human is able to process, prioritize, integrate, and learn information from these different sensory systems to create a rich and nuanced level of understanding of the surrounding environment. Humans then use this input information to make Intelligent decisions and drive outputs in order to take actions. These include such things as moving the body, performing spoken communication, and directly or autonomously controlling other bodily functions.
