Ranging and was first developed for military purposes. The word Detection stands for finding an object or target by sending out a radio signal. Merriam Webster defines radar as “a device or system consisting usually of a synchronized radio transmitter and receiver that emits radio waves and processes their reflections for display and is used especially for detecting and locating objects (as aircraft) or surface features (as of a planet). (Merriam Webster‚ 2012) The word Ranging means measuring the

correctly and matches the one of the words in the grammar text file‚ a code will be sent to the PIC 16f873P through the MAX 232. This command is then translated and sent to the PT 2262 to be encoded and transmitted to the PT 2272M4 via the transmitter TX/RX module to be decoded. This command is then sent to the PIC 16f873A to be translated according to the program preinstalled in the PIC. Based on the command‚ the PIC sends a specific command to the servo motors via L298N to operate either

The anode of the transmitter and receiver are connected to the 5 V power supply and cathodes are connected to the ground. When the bias voltage applied to the security alarm circuit‚ the transmitter emits the Infra-red ray. Then this connected to amplifier to amplify the low sound coming from transmitter.

message sender at the transmitter communicates with a message receiver. The sender selects one message from the finite set‚ and the transmitter sends a corresponding signal (or “waveform”) that represents this message through the communication channel. The receiver decides the message sent by observing the channel output. Successive transmission of discrete data messages is known as digital communication. Based on the noisy received signal at the channel output‚ the receiver uses a procedure known
