Today communication is the heart of the technology. Communication is achieved over a transmitter and a receiver through signals. These signals carry the information through modulation. Pulse Amplitude Modulation is one of the kinds of modulation techniques used in signal transmission. Pulse amplitude modulation is the simplest form of modulation. It is Analog to digital conversion method where the message information is encoded in the amplitude of the series of signal pulses.
Wireless communication plays a significant role in day to day life. Besides communication, wireless technology has become an integral part of our daily activities. The transmission of data or information from one place to another wirelessly is referred as wireless communication. This provides an exchange of data without any conductor through RF and radio signals. The information is transmitted across the devices over some meters to hundreds of kilometres through well-defined channels.

Motion sensors are commonly used in security systems. They work based on a wide variety of principles and are used in a wide variety of applications. Typical usage could be in the exterior doorways or windows of a building for monitoring the area around the building. Upon detecting motion, they generate an electrical signal based on which some actions are taken. Some operate in much the same way as a military radar scanner, while others work based on vibration, infrared radiation and, even sound. All of these different types of sensors have different strengths and weaknesses, which are important to take into account when making a decision to choose a particle motion detection sensor.

The system detects the LPG leakage using a gas sensor and flames by a flame sensor that alerts the consumer about the gas leakage by sending SMS with the help of GSM module which is connected preprogrammed microcontroller.
Heart attack (coronary artery disease) is one of the most common and very serious effects of aging. The cholesterol, fatty deposits, emotional stress, and drug intake lead to build spasm in blood vessel walls. As the spasm grows, less blood can flow through the arteries. As a result, the heart muscle can’t get the blood or oxygen what exactly, it needs. This can lead to a heart attack. In this article, We are developing a system which will help to decrease the death rate due to the heart attack by early heart attack detection. In our system, we will be using smart Heart Beat sensor which is easily available in the market.
Nowadays, the security system of the nation depending upon the enemy’s war and so the security of the soldiers is considered as an important role in it.

In soldiers security, biosensor system gives different kinds of sensors like small physiological, Barometric and Oxygen analyzer, processing capabilities and transmission modules, and can thus enable low-cost wearable unremarkable solutions for health monitoring system. The proposed system uses GPS to track the direction of the soldier in the form of latitude and longitude values. So that direction can be found easily.
GPS and GSM Based Soldier Tracking and Health Monitoring System
Designing of this system using GPS and GSM gives a wireless system for tracking the location of the soldier and observing the heart beat rate and body temperature of the soldier. The biomedical sensors used in the proposed system are sensor and beat. The temperature sensor is used to measure the temperature of the body as well as heart beat sensor is used to measure the heartbeat rate of the soldier.
One of the most important tasks in military processes is that the Soldier, not able to interconnect with control room administrator. In addition, every organization wants to apply for certain work when they communicate over the n/w owned and worked with other organizations. Therefore, without cautious planning and coordination, one group cannot interconnect with the other groups. Present a problem faced by the soldiers are; Soldier wants to identify the location. They will not get assistance during terror situation and soldiers are not trackable
Soldier unit is placed on the soldier. This unit has four parts, namely biomedical sensor, keypad, GSM, and GPS.
The Heart Beat sensor gives an easy way to study the function of the heart This sensor is used to monitor the blood through a finger. As the heart services blood through the blood vessels in the finger, the blood amount in the finger changes with respect to time. Heartbeat sensor shines a light lobe through the finger to measure the light communicated to the LDR.The signal gained from the LDR is changed by the amplifier and will be cleaned and provided to the ADC.
The Temperature sensor can be sensed with the help of the LM35 sensor. This series is accurate integrated circuit sensors, whose o/p voltage is linearly related to the Celsius temperature. A Station, which is pressed directly will aware Base station and thus will not delay for heart beats to go out of the normal range.
