This paper presents the design and construction of a machine that automates the process of selling access credentials to a wireless network. For its construction, the V methodology for project management was followed. The machine consists of a closed box with two buttons on the outside to indicate the start and end of the transaction, a 16x2 LCD screen with an I2c conversion interface to show transaction, user and password indications, a multi-currency purse and four LED lights that serve as indicators of the amount entered. Internally the machine consists of an ESP-8266-E development board, an Mb102 breadboard source module, a 12V 2.5A eliminator, a 5.0 V universal charger cube and a breadboard. Logically, the web-based spreadsheet (Google sheets), Google apps script and the Arduino integrated development environment were used. The result is a low-cost prototype, which provides controlled internet access credentials for multiple users.
The communication problem that the Nahua population of the state of Puebla currently have about medicinal herbs and alternative therapies is increasingly complicated, given that several cultural values are being lost, so it is an important opportunity to use digital media to rescue some remedies. The objective of this project is to develop an application to create and maintain a data repository that contains information on the medicinal plants used by the Nahua communities of the Huauchinango region. This project was born out of the need to communicate to future generations about the knowledge that is currently practiced in the Nahua communities about the properties of medicinal herbs in the region. The research work is carried out with the specialists of traditional peasant medicine with whom the diversity, use and management of medicinal plants classified by specialists of the Nahua peoples that they use to solve multiple diseases within their communities are documented. By having the system finished, the end user will be able to make queries about the medicinal plants, as well as the formula or recipe of the remedies. The administration of the repository can be done from a progressive WEB application.
This article presents the results obtained by implementing an application with an architecture based on the Internet of Things, applied to the production of red California earthworm, using an interface with which it is possible to monitor and collect data on temperature, humidity and PH with sensors that allow recording the necessary data. For the implementation, an experimental module was built in which the temperature and humidity variables were monitored, with the data obtained from the sensor measurements, the constant changes in temperature (between 20 to 29 ºC) and humidity (from 35% to 50%) were observed, This information made it possible to keep a weekly plan in which irrigation, aeration and compost mixing were attended to in a timely manner, reducing time, cost and human labor in the production of the red California earthworm and maintaining the reproduction of the red California earthworm in optimal conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
