The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3g. It can measure the static acceleration of gravity in tilt sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
The user selects the bandwidth of the accelerometer using the CX, CY, and CZ capacitors at the XOUT, YOUT, and ZOUT pins. Bandwidths can be selected to suit the application, with a range of 0.5 Hz to 1600 Hz for X and Y axes, and a range of 0.5 Hz to 550 Hz for the Z axis.
The ADXL335 is available in a small, low profile, 4mm × 4mm × 1.45mm, 16-lead, plastic lead frame chip scale package (LFCSP_LQ).
•Cost sensitive, low power, motion and tilt-sensing applications
•Disk drive protection

What is GPS Receiver?
GPS, which stands for Global Positioning System, is a radio navigation system that allows land, sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all weather conditions, anywhere in the world. The capabilities of today’s system render other well-known navigation and positioning technologies namely the magnetic compass, the sextant, the chronometer, and radio-based devices—impractical and obsolete. GPS is used to support a broad range of military, commercial, and consumer applications.

GSM Modem SIM900
What is a GSM Modem ?
A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile operator, just like a mobile phone. From the mobile operator perspective, a GSM modem looks just like a mobile phone.
When a GSM modem is connected to a computer, this allows the computer to use the GSM modem to communicate over the mobile network. While these GSM modems are most frequently used to provide mobile internet connectivity, many of them can also be used for making and recieving calls,sending and receiving SMS and MMS messages.
An RFID (Radio-frequency identification) reader is a device that is used to interrogate an RFID tag. The reader has an antenna that emits radio waves; the tag responds by sending back its data. Here Terminal software is used to show detected 12 bytes ID.
A number of factors can affect the distance at which a tag can be read (the read range). The frequency used for identification, the antenna gain, the orientation and polarization of the reader antenna and the transponder antenna, as well as the placement of the tag on the object to be identified will all have an impact on the RFID system’s read range.
This RFID works with 125kHZ Tx-Rx and reads 12 bytes code from the RFID tag. And is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. Some tags require no battery and are powered and read at short ranges via magnetic fields (electromagnetic induction).Others use a local power source and emit radio waves (electromagnetic radiation at radio frequencies). The tag contains electronically stored information which may be read from up to several meters away. Unlike a bar code, the tag does not need to be within line of sight of the reader and may be embedded in the tracked object.
This will gives you a very convenient and easy way to wirelessly communicate with your serial devices, regardless if they are new or old, and with the new Bluetooth serial 2.0, 3.0 and 4.0 protocols you get 128bit encryption for highly secure communications.
This serial Bluetooth is a good all-round unit for general wireless RS232 communication with printers, building control, scales, office equipment, alarm and security devices, CNC's and other manufacturing machinery. It can be powered by the included USB cable, a USB Mini power adapter, pin 9 at the DB9 connector or by an external battery.
You can configure this Bluetooth serial to communicate with most built-in or external USB Bluetooth dongles, in that case you will need only one Bluetooth serial adapter to setup a communication link. The parameters can however also be configured over Bluetooth if you have built-in Bluetooth or if you are using a USB Bluetooth dongle.
Zigbee is the latest advancement in wireless networking, working with utility providers and electronics manufacturers to create a convenient, energy-efficient wireless alternative. Zigbee allows a variety of electronic devices to interconnect through a single network, operated by a single remote.
The Zigbee network, in a sense, provides a global language by which a wide variety commercial and consumer products can communicate.Zigbee currently provides its home area networking (HAN) capabilities to various utility and energy providers. With this, the customer can conveniently control, for example, their lights, thermostat, and appliances from a single network.
