The Building Blocks of IoT
Sensors and Actuators
Sensors and actuators are the building blocks of IoT. They are the devices that allow IoT systems to collect data from the physical world and to interact with it.
Sensors
Sensors are devices that detect and measure physical quantities such as temperature, pressure, humidity, light, sound, and motion. They convert these physical quantities into digital signals that can be processed by other devices.
Sensors can be classified into two main categories: active and passive. Active sensors require an external power source to function, while passive sensors do not. Passive sensors typically use a physical process to convert the physical quantity into a digital signal. For example, a passive infrared sensor uses the thermal radiation emitted by a person to detect their presence.
Sensors can also be classified into two types based on their location: embedded and external. Embedded sensors are integrated into other devices, such as smartphones or wearables, while external sensors are standalone devices that can be attached to other devices.
Actuators
Actuators are devices that convert digital signals into physical actions. They can be used to control other devices or to perform a specific task.
Actuators can be classified into two main categories: electrical and mechanical. Electrical actuators use electricity to produce mechanical motion, while mechanical actuators use mechanical means to produce motion. Electrical actuators include motors, solenoids, and valves, while mechanical actuators include levers, linkages, and cams.
Actuators can also be classified into two types based on their location: embedded and external. Embedded actuators are integrated into other devices, such as smart home appliances, while external actuators are standalone devices that can be attached to other devices.
