Product Details
Serial Communication: The HC-05 communicates with other devices through a serial UART (Universal Asynchronous Receiver-Transmitter) interface. This means you can easily connect it to a microcontroller or any device with UART support for wireless data exchange.
Master and Slave Modes: The HC-05 can be configured to operate as either a master or a slave device. In master mode, it can initiate connections with other Bluetooth devices, while in slave mode, it can accept incoming connections.
Pairing and Authentication: The module supports pairing and authentication mechanisms to establish secure Bluetooth connections between devices. You can set up a PIN code for security.
Voltage Levels: The HC-05 typically operates at 3.3V, but some modules can be used at 5V with a voltage level translator or voltage divider for the UART signals.
Operating Range: The effective operating range of the HC-05 module is typically around 10 meters (approximately 33 feet), depending on factors like signal interference and the presence of obstacles.
AT Commands: You can configure the HC-05 module using AT commands. These commands allow you to change settings like the Bluetooth device name, baud rate, pairing code, and more.
LED Indicators: Most HC-05 modules have LED indicators to provide status information. They often indicate power, Bluetooth connectivity, and data transmission.
Applications: The HC-05 is used in various applications, including wireless data transfer between a smartphone and an Arduino or other microcontroller, Bluetooth-enabled home automation, and remote control of electronic devices.
Compatibility: The module is compatible with a wide range of microcontrollers and development boards, making it a popular choice for hobbyists and electronics enthusiasts.
When using the HC-05 Bluetooth module, it's essential to refer to the module's datasheet and documentation to understand its pinout, AT commands, and configuration options.
