This paper targeted to reduce the Queue at a billing counter in a shopping complex. The system does the same by displaying the total price of the product kept inside the cart. In this way the customer can directly pay the amount at the billing counter and leave with the commodities he/she has bought. It eliminates the traditional scanning of products at the counter and in turn speeds up the entire...
At present, technologies used in indoor positioning like Radio Frequency Identification (RFID) are based on wireless waves. However, various objects can reflect wireless waves, which cause complex multipath effect and non-line of sight transmission. Especially, people walking make errors hard to be corrected. Therefore, this article proposes a way that 940nm infrared ray replaces wireless wave tag...
With the improvement in standard of living of human beings, better home/office environment is required. Nowadays, intelligent home designs are becoming a trend in which intelligence can be built-in to provide improved user comfort at an incremental cost. However, many of the mature systems do not care about the energy savings. This paper presents a smart home solution with energy conservation in mind...
The main goal of this paper is to propose a simple and low-cost microcontroller-based laser communication link. To demonstrate that laser communication is a viable and efficient means for transmitting data, a transceiver capable of transfer rates of approximately 0.7 kB/s is prototyped. The hardware used for the transceiver consists of Commercial Off-The-Shelf (COTS) lasers, photodiodes, and the Arduino...
When information exchange occurs between people via a network, then authentication and security of data have more priority. This paper introduces a low cost, handheld, wireless electronic notice board by using Atmel's ATmega32 microcontroller and different wireless technologies (Bluetooth and ZigBee) and their performance analysis based on the parameter such as range, BER (bit error rate), RSSI (Received...
This paper proposes an advanced system for process management via a credit card sized single board computer called raspberry pi based multi parameter monitoring hardware system designed using RS232 and microcontroller that measures and controls various global parameters. The system comprises of a single master and multiple slaves with wireless mode of communication and a raspberry pi system that can...
One of the important directions for the gas metering is network transmission, such that the web gas management system can directly acquire the data of the gas usage for different customs, and give the billing and pricing without the human interaction. The gas meter is typically no wire connection for the safety consideration, so the wireless communication is necessary. An appropriate wireless module...
Tracking the position and the orientation of human limbs to reconstruct postures and actions is becoming a crucial need in several application domains, including medicine, rehabilitation, sport, and games. However, most available solutions are expensive, imprecise, or require an instrumentation of the environment. This paper presents a low-cost tracking system based on a set of wearable inertial measurement...
Currently, the main components of most sensor nodes are a microcontroller and a radio. Their real-time and peak performance would be a bottleneck when executing computation-intensive tasks. Also, energy consumption may be high due to the long task-execution time. Several works [2]–[6] demonstrate that adding a coprocessor would be a solution to the problems. So far, no work have been done to analyze...

The design...
Humans have been constantly striving to make life simpler and more organized. With rapid advancement in electronic technology, we have all sorts of gadgets to interact with the physical world around us. For such an application, Touch screen technology is yet another promising platform, but has hardly been explored. In our project, we used touch screen to control the movement of a bot as precisely...
The project aims at developing a prototype boat that is capable of autonomously sailing and navigating its way through obstacles present around it. Apart from moving on a pre defined path the boat can intelligently avoid obstacles in the path through its ability of decision making using fuzzy logic. Calculations of fuzzy logic as well as deciding inputs for the path direction to be sent to the micro...
Programmable embedded systems which are configured through a cable for operation, typically are inaccessible for reprogramming after deployment. Cheaper systems tend to be deployed in large numbers like Wireless Sensor Network (WSN) nodes forming a mesh network. In such cases, a reconfiguration or upgrade of firmware is difficult. A wireless channel for programming with broadcasting features addresses...
In this paper we present BRIX, a novel modular hardware prototyping platform for applications in mobile, wearable and stationary sensing, data streaming and feedback. The system consists of three different types of compact stack-able modules, which can adapt to various applications and scenarios. The core of BRIX is a base module that contains basic motion sensors, a processor and a wireless interface...
