Description

The Bluetooth HC05 module is a commonly used wireless communication module that allows devices to communicate with each other over short distances using Bluetooth technology. The HC05 module is a small, low-power Bluetooth radio module that can be integrated into various electronic devices such as microcontrollers, Arduino boards, and other embedded systems.

One of the key features of the HC05 module is its ease of use and low cost, making it an ideal choice for hobbyists and enthusiasts who want to add wireless communication to their projects. The module can be paired with other Bluetooth-enabled devices, such as smartphones or laptops, allowing for easy data transfer and control.

Some common applications of the HC05 module include wireless data transfer, remote control of devices, and wireless sensing and monitoring.

Here are some technical specifications for the Bluetooth HC05 module:

– Bluetooth version: Bluetooth v2.0+EDR (Enhanced Data Rate)
– Frequency: 2.4GHz ISM band
– Modulation method: GFSK (Gaussian Frequency Shift Keying)
– Transmit power: ≤ 4dBm, Class 2
– Sensitivity: ≤ -84dBm at 0.1% BER
– Data rate: 2.1Mbps maximum, 1Mbps typical
– Operating voltage: 3.3 to 5V DC
– Operating current: ≤ 40mA (when connected), ≤ 8mA (standby)
– Operating temperature: -20°C to +75°C
– Dimensions: 26.9mm x 13mm x 2.2mm
– Interface: UART/TTL (Universal Asynchronous Receiver/Transmitter)

The HC05 module uses a 4-pin header interface for power supply, ground, TX (transmit), and RX (receive) signals. The module can be configured using AT commands, which allow for setting the baud rate, Bluetooth device name, pin code, and other parameters. The module also supports multiple connection modes, including point-to-point, point-to-multipoint, and broadcast. The maximum range of the HC05 module is up to 10 meters in open space.
