Description

The IoT enabled projects require two way communication between the microcontroller and various sensors. There are various methods you can do that, Wired Communication, WiFi, Bluetooth are some among them. The HC-05 Bluetooth Module adds wireless communication to your project to communicate via Bluetooth to any Bluetooth enabled Laptop or Mobile Device. The module communicates at 9600 baud rate via USART protocol. It can be used in applications like communication between two microcontrollers, data logging, wireless robots, wireless sensors data acquisition and home automation.
