Sensors

Sensors are the primary source of data for an IoT solution.

Sensors are devices that can detect the physical properties of the environment around them, convert the physical properties into electrical signals (analog or digital), and transmit the information to a processor either directly or through a gateway. Sensors can be electrical, electronic, mechanical, biochemical, or a combination.

Physical properties that sensors can detect and capture include almost everything humans can sense or experience and many others that humans cannot. Sensors can detect temperature, humidity, pressure, light, motion, touch, sound, acceleration, vibrations, moisture, and many more properties. The only exclusions at this time probably are taste and smell. Although, sensors can detect the presence of a gas using chemical reactions, which humans may detect with their sense of smell.
