We all know that one of the places where power wastage happens most in homes and offices is at staircases. We usually turn on light at stairs and leave it in a hurry. In this project we are going to design a stair case lamp which works on battery and only turn on the lights only […]

Determining the state of our health has always been a matter of finding a way to monitor and measure the body’s most basic functions. Before instrumentation, visual indicators were used that allowed us to know, for example, what our body temperature should be, what a healthy pulse is, and what an acceptable respiration rate is.

Cypress Semiconductor has introduced what it believes to be the lowest-available-power PMICs that enable an integrated module size of 1 cm² for solar-powered wireless sensor node (WSN) designs. Intended to manage solar-powered wireless sensors for Internet of Things (IoT) applications, these parts are said to be the lowest-power, single-chip Energy Harvesting PMICs, and can be

Summary This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being

Introduction This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed. A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that
Introduction The I2C is a multimaster, multislave serial single-ended computer bus and was invented by Philips in 1982. The atmel microcontrollers use a compatible to I2C serial bus that is named TWI (Two Wire Interface). The TWI supports serial communication at 100 kHz and 400 kHz. The master and slave devices that are connected to TWI bus

Temperature sensors are widely used in electronic equipments to display the temperature. You can see the digital clock displaying the room temperature value. It is due to the temperature sensor embedded in it. Generally, temperature value is analog. It is converted to digital value and then it is displayed. This article describes the same converting

Introduction For this project, we created a noninvasive heart rate and blood pressure measurement tool with the intention of gathering data for large-scale analysis for the automatic prediction of heart disease. In modern society, patients often have access to a wealth of electronic data concerning their social networks and surroundings, but have little personalized insight

For our ECE4760 final design project, we designed and built a two player game system for rock-paper-scissors. Our implementation involved the use of two sensor gloves (one for each player) that tracked bends in the user’s fingers, to determine the symbol put out by each player, as well as hand acceleration, to track the start

Introduction This project was designed to aid a research study by Cornell Professors Bob Nafis and Yingxin Gao on the reasons behind the higher rate of ACL injuries suffered by female athletes. This injury rate can be up to three to eight times higher than the rate of similar injuries suffered by male athletes. The
