# EcoSen - Registradores de datos abiertos (o lo más abiertos posibles) para variables ambientales (English below)
El monitoreo ambiental es esencial para el cuidado del ambiente. Particularmente, me interesa poder monitorear ambientes acuáticos. Para medir estas variables una opción son los registradoresd e datos privativos. Estos debido a sus altos costos, o por ser de diseños cerrados nos imposibilitan compararlo o repararlos.
Nuestra propuesta consiste en el diseño y desarrollo de registradores de datos (RD) con tecnologías inalámbricas para tener información en tiempo real en cualquier dispositivo conectado a internet. Los RD pueden ser tanto acuáticos como terrestres. Los acuáticos se espera puedan medir información relevante para el cálculo de índices de calidad de agua ([Pesce y Wunderlin, 2000](https://www.sciencedirect.com/science/article/pii/S0043135400000361)), como ser turbidez, oxígeno disuelto, conductividad y pH. El terrestre va a medir aquellas variables relevantes para la calidad del aire o suelo.
La base técnica para la construcción de estos registradores es la presente en el increíble proyecto [Cave Pearl Proyect](https://thecavepearlproject.org/), pero adaptandolo a aguas superficiales.

### Descargo de responsabilidad
Este proyecto se encuentra en gestación por lo que vamos a ver es su evolución. Aún no hemos logrado un perfecto funcionamiento de lo propuesto ni con todo tipo de sensores ni con la conectividad inalámbrica, así que cualquier persona que se quiera sumar es bienvenida. Puedes comuncarte con alejo.bonifacio@unc.edu.ar
## Motivación
Queremos traer a la sociedad la pasión por el monitoreo de ríos, lagunas, lagos y todo tipo de humedales. Además, reconocemos la importacia de aprender acerca de aprender acerca de proyectos de electronica abierta con la posibilidad de reproducir, modificar y personalizar los RD. La tecnología abierta que queremos compartir es asociada a repositorios que harán de la información accesible a cualquier persona. Si en algún momento crees que alguna información no es lo suficiente pública por favor nos lo haces saber.
## Primeros pasos
[//]:# ### The first steps, measuring
To begin recording environmental variables is necessary to develop some abilities measuring these. To do that we are gonna start making a [Coqui conductivity sensor](https://publiclab.org/wiki/coqui) of [Public Lab](https://publiclab.org/) website.
<img src="Images/Coqui.jpg" width="100%">
With this task, we are learning to measure environmental variables with an open source hardware
### Second step, logging
To begin logging we are going to made an Arduino Uno based data logger. This data logger is based in one of the [Cave Pearl Projects] (https://thecavepearlproject.org/2015/12/22/arduino-uno-based-data-logger-with-no-soldering/). After complete the datalogger we are going to add a DHT11 temperature and relative humidity module to pin 8 of Arduino Uno. The code.ino is downloadable in the following [link](https://drive.google.com/open?id=17P1dIhY--dl7_n6sXm4gY56F4k5InGaj)or in the Codes folder.

### Features
This data logger is designed to function similarly to the [Cave Pearl Proyect data logger](https://thecavepearlproject.org/category/diy-build-a-pro-mini-logger/) designs:
* __Autonomous:__ this data logger has an autonomy of several months
* __Customisable:__ Allows to choose what sensor you want for your data logger
* __Wireless communication:__ Thanks to the LoRa connectivity this device can send a measurements to a server and get access to the information wherever you are. This feature is new to the Cave Pearl Proyect data logger.
We chose a Arduino pro-mini to be the "brain" of this data logger for its versatility, accessibility, simplicity, and ability to add and upgrade your own modifications. Any method with which you can communicate with a arduino pro-mini (bluetooth, WiFi, LoRa, etc) can be added to the data logger to get the information from its.

### Do you want to contribute to the project?
This project need people interested in contribute in different tasks. In order to collaborate with this project, you will need to have some experience in the following:
* __Coding arduino microcontrollers:__ Although we are already working in the code for the full data logger, improvements of the code are always necessary the best code possible for the device.
* __Electronics:__ This project uses components like sensors, different modules, and batteries.
* __Community management:__ We need some expertise in the use of social networks and content production.
Most of the above are skills that you can learn and pick up fairly quickly from watching videos and doing research on the internet, and throughout the project we try to give supplemental information on some of these as well. See the build documents for more information.
If you want to contribute please send me an email to: alejobonifacio@gmail.com

# EcoSen - Data-Loggers and sensors for environmental quality (Español abajo)
Environmental monitoring is essential due to the variety of ways in which it is threatened.
Usually recording environmental variables can be carried out by private data loggers. These devices, due to their high costs, or being of closed design, do not allow us to buy in quantity or build them.
