I used to live in front of a beautiful but polluted lake in Londrina city. Now I live in Curitiba city, some say the most ecological Brazilian city.
Urban socio-environmental problems identified in Curitiba includes air pollution, water pollution and environmental degradation (references).
This project is developed with the objective of creating low-cost water monitoring stations, enabling the creation of a dense monitoring network with the capacity to locate occurrences of water pollution and contamination.
With community and educational purposes in mind, information about suppliers, configurations, and software are all open-source.
The current state of the project is hardware and software prototyping. The prototype was tested on the Atuba River, near a place known as Ecobarreira do Atuba. The prototype is current deployed at Igapó Lake 2.
This is the prototype deployed at Igapó Lake 2:
This is the prototype deployed at Ecobarreira:
The prototype in greater detail:
Inside the box:
- Atlas Scientific Wi-Fi Pool Kit (Legacy, with ESP8266). It has pH, ORP (Oxidation Reduction Potential) and Temperature probes and comes with Wi-Fi connectivity.
- LILYGO® T-SIM7000G. For cellular connectivity this low-power, low-cost board comes with Espressif's ESP32 microcontroller, SIMCom's 7000G cellular modem, battery holder and solar power circuit at around 300 Brazilian Reais. ESP32 is more capable than Arduino and less expensive than Raspberry Pi.
- LILYGO® T-A7670SA R2. Similar to T-SIM7000G but this one have Cat 1 protocol support, enabling future connection to Starlink's "Direct to Cell".
Atlas Scientific has a a broad range of probes such as Conducitvity and Dissolved Oxygen. Alsos several other locations can be monitored.
