Module Introduction
ESP32 Devkit Development Board: Features a built-in dual-core Xtensa 32-bit LX6 processor with a clock speed of up to 240MHz, 448KB ROM, 520KB SRAM, and 16KB RTC SRAM, along with 4MB of external Flash memory. The board also provides up to 26 I/O ports and supports Bluetooth and Wi-Fi connectivity.
ESP32 Expansion Board: Utilizes the XH2.54 standard reverse-insertion interface, effectively preventing incorrect connections and simplifying connection steps, thereby improving development efficiency. An onboard power regulator chip ensures stable circuit operation, while the two rows of pins provide flexible wiring options.
LED Module: The LED module is an integrated high-efficiency lighting unit that can be used as an indicator light.
Button Module: The button module is an electronic switch component that integrates physical buttons, circuitry, and signal processing functions. Its large size design provides a more comfortable pressing feel and easier operation.
IR Receiver Module: An electronic component used to receive and decode infrared remote control signals. It converts invisible infrared light pulses into digital signals recognizable by a microcontroller.
Active Buzzer: A sound-generating component with integrated drive circuitry. It sounds continuously at a fixed frequency when powered on, typically used for alerts or alarms.
Motor Fan Module: Consists of a DC brush motor, plastic fan blades, and a motor drive circuit, integrating speed regulation and stabilization functions.
RFID Sensor Module: A device that reads and writes electronic tag data non-contactly using radio frequency signals, commonly used for identification, access control, and item tracking.
DHT11 Sensor: A digital composite sensor module integrating temperature and humidity sensing elements. It outputs calibrated digital signals via a single-bus protocol and is commonly used for basic environmental monitoring.
LIGHT Sensor: An electronic component that uses a photoresistor to sense ambient light intensity and converts it into an analog or digital signal output.
Raindrop Sensor: A detection component used to detect the presence of water droplets or rain on a surface. It outputs a signal by measuring the change in circuit impedance caused by raindrops, and is commonly used in intelligent sensing systems such as automatic window closing.
PIR Sensor: A passive sensor that detects movement of a person by detecting changes in infrared light emitted by the human body at a specific wavelength. It is commonly used in automatic lighting and security alarms.
RGB LED Strip: An intelligent LED strip module composed of 8 independently controllable RGB LED beads connected in series. The color and brightness of each LED bead can be precisely and dynamically controlled via a single-wire digital signal.
LCD1602 Screen: A commonly used character-type liquid crystal display module that can display two lines simultaneously, each line containing 16 English letters, numbers, or common symbols. It communicates with the main controller via an I2C interface.
SG90 Servo Motor: Receives pulse width modulation (PWM) signals and accurately converts the pulse width into the rotation angle of the output shaft.
Infrared Remote Control: A handheld transmitter that wirelessly sends control commands to electrical devices by emitting encoded and modulated infrared light pulses through infrared LEDs.
