This document describes the design of a low-powered wireless security device using a radio frequency (RF) transmitter and passive infrared (PIR) sensor. The system is divided into two hardware units - a sensor unit with PIR sensors interfaced to an RF transmitter, and a computational unit with a microcontroller interfaced to an RF receiver and alarm system. The microcontroller-based system detects intruders via the PIR sensors and wirelessly transmits a signal to trigger an alarm. It aims to provide security with low power consumption to operate on batteries for longer. The system was tested and able to detect movement at distances up to 7 meters with components operating between 4-12 volts and power consumption as low as 1.
Ijeee 33-36-surveillance system for coal mines based on wireless sensor networkKumar Goud
Abstract: The foremost critical task for coal mine is of keeping track of miners spread out across a large mining areas .It becomes even difficult when mine tunnels collapse. Many mines use a radio system to track miners, but when a collapse occurs, the base stations connected by a thin wire often are rendered useless. In this project to overcome the demerits of radio system we used wireless technology for tracking the miners. For this purpose a small RF transmitter module is equipped to each person entering a mine. Each transceiver placed in the mine look after the location of miners. The transceivers communicate with base stations through Zigbee module. In addition of tracking the location of miners we also include sensors such as temperature & humidity to intimate the base station & miners when some atmosphere changes occur. Mine operators are now able to monitor the real-time locations of each miner to better pinpoint their locations in the event of an emergency. Even after a full-day of use, mine operators can locate an individual miner within ten feet.
Key Words: Wireless sensor networks (WSN), ZIGBEE, and LPC2148.
My solution for this involves IoT device fixed on the safety jacket which is called Smart safety jacket.The Smart Safety Jacket enables complete safety of the employees working in mining and construction industries by installing a different type of sensors like Temperature sensor, Humidity sensor, Ultrasonic sensor, Motion sensor, Gas sensor, Sound sensor, RFID, Emergency Panel, and Notification Panel. These sensors connected to the network through Wi-Fi makes more relevant and valuable ever than before. In case of emergency, immediate notification will be sent to an admin who is monitoring entire miners in the mining industry and immediate action will be taken to rescue miner from the hazard.
The whole process can be stated in two points.
1. The miner has to wear the smart safety jacket (connected with the sensors) which is connected to the control room via a network.
2. A Monitor in the control room who is continuously monitoring the miners and the mining site should check the hazard status and alert and rescue the miners in case of any critical situation.
Thus the mining environment and miners will be protected from the hazard.
With the advent of technology, life has become faster in pace and shorter in interactions, with others, as well as with the surroundings. In such a scenario, there is a need to have an endeavor to have everything at the push of a button away, and more importantly, automated. Home Automation is such an endeavor, in which, all the electrical appliances present at home are connected to each other, having interactions with sensors placed at strategic positions in a closed loop manner in order to perform meager tasks automatically, leaving less burden on the humans. With this project we are promoting the fact that Home Automation can greatly contribute to energy conservation too.

Application of Zigbee in Smart Home with Dynamic Routing AlgorithmNooria Sukmaningtyas
In order to avoid damaging the walls and bore a hole through the walls, also to save the cost of
rewiring, low voltage power line can be used to implement the smart home. However, several difficult
problem must be solved at the same time , the most important are finding a technology method to
suppress the noise interference and resist the weaker signal. The smart home system is introduced in the
paper. During the design of Smart Home System adopting power line signal carrier, a dynamic routine
algorithm based on the idea of Genetic Algorithm is proposed to cope with the time-varying and random
feature of power line channel. Thus the system can find the transmission path in real time and dispatch the
signal carrier to transmit among the nodes. With this algorithm, the communication between a certain
group-controller and its terminal nodes or between the main-controller and the group-controllers is realized
successfully. In the proposed algorithm all nodes but the controller adopt same driver, therefore the plug
and play is realized for all nodes.
In this paper we have to design and implement
surveillance system by use of smart sensors like ultrasonic
sensors and pyroelectric infrared sensors (PIR) to detect an
intruder in a home, ATM, Industries, Bank Locker room or a
storehouse. The PIR sensors are placed on the ceiling, and the
ultrasonic sensor module consists of a transmitter and a receiver
which are placed vertically on the wall. We are going to use the
camera to capture images of the people those are coming under
the surveillance area. And we are sending these images to
authorized and related personnel via e-mail to avoid the storage
cost. This system will also help to reduce the power consumption.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
