Dispositivo Electrónico Para La Medición De Temperatura Y Humedad Del Suelo, Sergio Alejandro Vaca Vargas, Esteban Serrano Vivas

Ingeniería en Automatización

El presente documento se describe un proyecto de investigación, el cual fue realizado para el Instituto de Hidrología, Meteorología y Estudios Ambientales IDEAM, donde se implementó una metodología de ingeniería inversa encaminada a la aplicación de tecnologías propias para la generación de un nuevo dispositivo capaz de realizar la medición de temperatura y humedad del suelo, partiendo del diseño del circuito electrónico, pasando por la simulación y llegando finalmente hasta la disposición de los componentes electrónicos sobre una placa de circuito impreso (PCB), todo lo anterior basándose en un equipo existente para la identificación de componentes electrónicos, curvas de comportamiento, …

Design And Testing Of A Turbidity Sensor For Grain Size Measurements, Sara Rebeca Martin Cid

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Grain-size analysis is a measurement of the size distribution of individual particles in a soil sample. The major features of grain-size analysis are the destruction or dispersion of soil aggregates into discrete units by chemical, mechanical, or ultrasonic means and the separation of particles according to size limits by such means as sieving and sedimentation, as well as other methods.

Soil particles span a large size range, varying from boulders (exceeding 0.25 m in size) down to submicron clays (Grain-size distribution curves are used extensively by civil engineers to evaluate materials used for foundations, road fills, and other construction purposes. …

Characterization Of A Mems Accelerometer For A Highway Health Monitoring Ultra-Low Power Sensor, Karla Cecilia Enriquez

Open Access Theses & Dissertations

With the 2009 American Recovery and Reinvestment Act, government officials recognized the need to implement automated methods that reduce the cost of assessment projects and provide a long-term solution to monitor the structural health of bridges and highways. Although important research exists in the area of non-destructive evaluation, current road health monitoring efforts continue to be costly and time consuming. This Thesis focuses on the characterization of a MEMS accelerometer intended to be the basis of a novel ultra-low power sensing system to remotely asses the condition of highways. The architecture of a sensor prototype built to validate an algorithm …
