HC-05 Bluetooth Module

HC-05 Bluetooth Module

The microcontroller and various sensors must be in two-way communication for IoT-enabled projects. There are many ways to do that, including Bluetooth, WiFi, and wired communication. Your project can now communicate wirelessly with any Bluetooth-enabled laptop or mobile device using the Hc 05 bluetooth module. The module uses the USART protocol to communicate at a 9600 baud rate. Applications for it include data logging, wireless robots, wireless sensors, data acquisition, and home automation. It can also be used for communication between two microcontrollers.
