By analyzing atmospheric values, this tiny unit can decide when to irrigate your garden if it is necessary.
Project in progress by Daniel Rossi
A wireless headset which allows you to control devices through cerebral waves. It works with two sensors and a Bluetooth shield.

For this project i used a protocentral's board which mounts an ads1292r. You can still find something similar on protocentral, but i don't think that it is the same board i used: https://protocentral.com/product/ads1292r-ecg-respiration-shield-for-arduino-v2/
it still mounts the ads1292r, so the project is still feasible , but it could be necessary to completely renew the project because the board i used is now dated (the circuit architecture could be different).
Anyway, there was no documentation when i started the project. Now this board is fully documentated with code and circuit examples so i think you can do it! :)
thank you for taking an interest in the project! :D
we have spent around 130 USD to buy all the necessary tools (ads1292r, 2x bluetooth shield, arduino uno, etc.), without the costs of the headset and sensors which are handmade.
