Hi, I have multiple ESP32 dev boards, what I'm using like a magnetic detector (with inbuild hall sensor) With one ESP32 it's not a big problem (code attached = combination of web server & hall sensor example). Question is, how can I send this info from multiple ESP32 boards into one website? (See attached image) Thanks
...would like to build an Android Wear Application. The application needs to be able to register a user and his/her emergency contact information and interface with a heart beat sensor (on a smart Android watch). If the heart rate is below or above a certain level then a notification with the current location is sent to the emergency contact information.
PROJECT COMPLETION DATE: 19TH OCT 2018 We require an industrial designer to improve an existing product concept. The product is an outdoor air quality sensor, which needs to have a feature that enables it to mount to trees or outdoor walls, on either flat, curved or corner surfaces. These will require some industrial design skills to create, model
