The GeoSensor – A Low cost weather station

The GeoSensor is a new IoT-based project by Hugo Lavalle, an Arduino and IoT fan.

The main scope of the project is to provide makers with a low-cost weather station that will allow users to have direct access to meteorological data.

The idea behind this effort has come from the fact that Hugo is a sailor and have always wanted access to meteorological data from the place he usually sails. Most likely a commercial weather station is too expensive, so he decided to build one himself.

These are the main components proposed for the basic version of the project:

  • Wind and rain sensors
  • Arduino microcontroller
  • Ethernet shield
  • Temperature sensor
  • Cables, electric material, arduino case, etc.

Hugo has just launched a crowd-funding campaign for his project and is going pretty good. In case the project gets the funds, he will donate the first station to the marina he uses for sailing, that is located at the Parque da Cidade, in Jundiaí/SP.

Source code and h/w schematics will be released as Open Source at the end of the project.

In case the fund raising goes well, Hugo plans to add more features like:

  • Including more sensors, like air and soil humidity.
  • Enabling alarms for heavy rains, that may cause flooding and mudslide, frequent problems here in Brazil during summer rains.
  • Investigating the possibility of measure river levels.
  • Building a wireless station, wih wifi or a zigbee/ethernet gateway.
  • GPS integration.
  • Building a mobile station with GPRS connection.
  • Using solar power

Hugo reports that the book has helped him a lot with his project! Thank you so much Hugo and good luck with your project! 🙂

UPDATE (26/6/2012): Hugo reports that after having the first prototype ready, he will propose the creation of a national GeoSensors network. In that network, each participant would be a maker and/or manager of a GeoSensor. The resources could be obtained also from crowd funding. More details on the website that Hugo shares the progress of the prototype.
