XBee 1mW Wire Antenna 

Description

Finally user can enjoy another simple yet reliable wireless communication for robots. XBee OEM RF module has been used in many robotics applications world wide to offer wireless communication, point to point and also mesh network. No more searching for surrounding device and request for connection, it can send data wireless after powering up without any extra configuration. Additionally, the communication range is very good (100 meters) for a low powered device (1mW). Its small form factor saves valuable board space. No configuration is necessary for out-of-box RF communications. XBee module comes with application software to ease user in editing configuration and also for functional testing. Since the XBee module pin is 2mm pitch to pitch (is difficult to plug in standard board), you can use SKXBEE as starter kit.

XBEE STARTER KIT 

Description

XBee has becoming extremely popular among robot builder and embedded wireless communication. It can be use for control and monitoring, data streaming, real time wireless update and also wireless downloader.Finally user can enjoy another simple yet reliable wireless communication for robots. However, using XBee OEMRF module need extra work to interface since it is 3.3V power and offer 3.3V interface. With these reason, Cytron Technologies has designed Starter kit for user to easily use XBee module. With SKXbee, useronly requires 4 simple wiring to offer wireless communication to 5V microcontroller. On board USB interface, can easily turn SKXBee into XBee dongle.

Dimension: 8cm x 4cm

IR Sensor Set 

Description

The IRS-01 IR sensor set consists of an IR transmitter and an IR receiver mounted side by side on a tiny PCB. With a 5 VDC power, it can be used as a reflective type IR sensor for mobile robot or any simple control system.

Dimension: 1.2cm x 1cm

Sharp Analog Distance Sensor (10-80cm)

Description:

The Sharp distance sensor is a popular choice for application and development that require accurate distance measurements. This IR sensor is more economical than sonar range finders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital (ADC) converter for reading distance measurements. The output can also be connected to a comparator for threshold detection.

Specification:

• Similar specification to GP2D12
• 4.5V to 5.5V operating voltage.
• Working distance from 10cm to 80cm.
• Analog Output
• Output voltage change over distance (2.45V - 0.45V)
• Come with Connector and Wire
