This project aims open source prototypes for monitoring the environment using free-design hardware and open source software. The first prototype has a tree unit station and a base station. The tree station gets data from the tree and the environment before sending the data to the base station that will be interconnected to the InterSCity Platform. The stations has been developed in partnership with the group managed by Prof. Marcos Buckeridge, from Instituto de Biociências – Universidade de São Paulo in the context of the INCT InterSCity.
By now, the units offer:
The sensor stations were produced with a focus on low-cost hardware considering that the main idea is to reproduce the stations in large scale and monitor big cities. The hardware and software used in these stations were:
A better description of each unit of the station is described in next sections.
The first prototype was created by Anne-Camille and Oumeima during their internship at Universidade de São Paulo. An Arduino-based sensor station was created using low-cost components and inspired other solutions available on the market. The hardware-design is presented below.
In order to protect the final hardware, a 3D case was projected. This case fits all the sensors, hardware, and batteries. The idea of using an Arduino Nano over a breadboard was intentional. This approach allows other sensors to be easily attached without modifying the case in most of the cases. Below we have some images of the front and back side of the protective case.
The first prototype of the web portal was also developed by Anne-Camille and Oumeima. This portal shows the data available at the Raspberry Pi base station. A single visualization of this portal is presented below.
