Sensors and Actuators
This chapter explores the critical roles of sensors and actuators in Internet of Things (IoT) systems. Sensors gather data from the environment, while actuators execute actions based on that data. Various types of sensors and actuators, along with their applications and interfacing methods with microcontrollers, are discussed in detail.
Sections
Sensors detect and measure physical properties and convert them into digital or analog signals.
Actuators are devices that convert electrical signals into physical actions, enabling systems to respond to sensor data.
This section explains how to interface sensors and actuators with microcontrollers, including the use of digital and analog pins.
This section explores practical applications of sensors and actuators in real-world IoT systems.
Sensors detect and measure physical properties and convert them into signals.
Actuators convert electrical signals into physical actions.
Microcontrollers interact with sensors and actuators through digital, analog, and PWM signals.
Sensors
Devices that detect and measure physical properties like temperature and light, converting them into digital or analog signals.
Actuators
Devices that convert electrical signals into physical actions, such as moving or switching operations.
Interfacing
The method of connecting and communicating between sensors, actuators, and microcontrollers.
Microcontrollers
Integrated circuits that manage the operations of sensors and actuators and process data.
