Bluetooth module (Bluebee) 

BlueBee wireless module is new product from Cytron Technologies, utilizing the XBee form factor, BlueBee is compatible with XBee adapter such as SKXBee (without module), XBee breakout board and Arduino-XBee shield. Though the form factor (pin out) is compatible with XBee module, BlueBee uses Bluetooth Technology. It is compact in size, the pinout is compatible with XBee which is suitable for all kinds of microcontroller systems that have 3.3V power out, the module utilize AT commands to set baud rate and other parameters. The BlueBee module comes with an on-board antenna, the antenna provides better signal quality. It acts like a transparent serial port, which works with a variety of Bluetooth adapter and Bluetooth phone. However, it only provides SPP (Serial Port Profile) where it becomes serial COM port once it establish connection with master Blueooth. BlueBee module's baudrate can modified using XBEE adapter. You can use SKXBEE-BOARD or XBEE Arduino controller receives the base plug, enabling Bluetooth wireless control.

Cytron XBee Shield

This is the newly designed XBee Shield. It is a XBee expansion board that design for Arduino and you need to buy a XBee module separately. Xbee radios are an awesome way to add wireless capability to your Arduino project and now it's even easier with the XBee Shield. The serial pins (DIN and DOUT) of the XBee are connected through jumpers, which allows you to select a connection to either the UART pins (D0, D1) or any digital pins on the Arduino D0, D1, D2, D3, D8, D9, D10 and D11. It even provides the option to connect XBee UART pin to USB's UART pin. This feature offers flexibility to use hardware UART or softserial on Arduino. Power is taken from the 5V pin of the Arduino and regulated on-board to 3.3VDC before being supplied to the XBee. The shield also takes care of level shifting on the DIN and DOUT pins of the XBee.The board also includes LEDs to indicate power and activity on DIN, DOUT, RSSI, and DIO5(ASSOC) pins of the XBee. The Arduino's reset button is brought out on the shield, and we reserve a space with 0.1" holes for prototyping. The shield does come with headers installed.

Bluetooth module HC-06

The popular HC-06 Serial (UART) Bluetooth module is widely used to add wireless functionality to microcontrollers such as the Arduino.

Features:

• SLAVE mode only (the PC, telephone or other device must initiate the pairing and connection)
• 3V OPERATION (5V will not work)
• 4PIN connector (this does NOT connect to the normal 3PIN connector)
• 4PINs are Vcc, GND, DO (TX), DI (RX) This cable works perfectly with this brick: 4 Pin Dual-female Jumper Wire - 20cm(Parallel)
• Dimensions: 3.7cm × 2.1cm × 0.8cm

Conclusion

After done researching about Bluetooth module i decide to use bluetooth module HC-06, This is because this module is cheaper compare with other and it easy to use also easy to setting this module.
