4 Current trends in home AUTOMATION In simple installations, AUTOMATION may be include remote as straightforward as turning on the lights when a mobile control, person enters the room. In advanced installations, automated lights, rooms can sense not only the presence of a person automated inside but know who that person is and perhaps set appropriate lighting, temperature, music levels or surveillance.

Gas leak detection is the a pyro electric device that detects motion by process of identifying dangerousgas leaks by measuring changes in the infrared (heat) levels sensors. These sensors usually employ an audible emitted by surrounding objects. When motion is alarm to alert people when a hazardous gas has detected the PIR Sensor outputs a high signal on its been detected. Common sensors include infrared output pin. This logic signal can be read by a point sensors, ultrasonic sensors, electrochemical microcontroller and can be used to control other gas sensors, and semiconductor sensors. Recently, circuitry. The delay time / blocking time are infrared imaging sensors are come into use. All of adjustable using the potentiometers on-board.

8 It can these sensors are used for a wide range of detect the signal from 10-12 feet. Its operating applications and they found in industrial plants, voltage is 5V DC. This sensor can be used to detect refineries, waste-water treatment facilities, theft in a home when owner not present. vehicles, and homes. Fig. 2 PIR sensor Temperature Sensor-LM 35 is an integrated circuit temperature sensor which can be used to detect the temperature in a centigrade scale( 55 C to 150 C).The LM35's low output impedance, linear output, and precise inherent calibration make Fig. 4 MQ-6 LPG Gas sensor interfacing to readout or control circuitry it draws only 60mA from its supply, it has very low self- RF Transmitter and Receiver-This RF module, as this SYSTEM , it is used to adjust the the name specifies, operates at Radio Frequency.

In this RF SYSTEM , the digital data is measure high voltage range than that of represented as variations in the amplitude of carrier thermocouples. wave. This type of modulation is known as Amplitude Shift Keying (ASK). Transmission through RF is much better than IR (infrared) due to many reasons. Firstly, signals through RF can pass through larger distances making it suitable for long range applications. Second IR mostly operates in line-of-sight mode; Radio Frequency signals can travel even when there is an obstacle between transmitter & receiver. Next, RF transmission is Fig. 3 LM35 Temperature sensor stronger and reliable than the IR transmission.

The safety SYSTEM . This type of component is used to transmission of RF signals occurs at the rate of detect a gas leak and interface with a control 1 Kbps - transmitted data is received SYSTEM so the process can be automatically shut by RF receiver operating at the same frequency as down. A gas detector sound an alarm to user in the that of the transmitter. area where the leak is occurring, by giving them the opportunity to leave. These type of device is important because there are many gases that may be harmful in a life, such as humans or 1222. All Rights Reserved 2016 IJARCET. ISSN: 2278 1323.
