Interfacing sensors and actuators with ESP32
In this section, we’ll dive into the hardware components of our home monitoring and control project. Here, we will explore the seamless integration of a wide range of sensors and actuators with the ESP32 microcontroller, allowing us to transform our ordinary home into a smart and efficiently managed living space.
Our project hinges on the precise coordination of various elements to log data and monitor different rooms in our home, offering us valuable insights and control. To achieve this, we will connect the ESP32 microcontroller to a set of essential components, including DHT22 sensors, motion sensors, Light Dependent Resistor (LDR) modules, and an additional servo motor for the living room.
Each room in our home as depicted in Figure 8.1, will be equipped with a set of sensors. The DHT11 sensors will provide temperature and humidity data, the motion sensors will detect human presence, and the LDR modules will measure light...
