LEWE – an open source biometric wristband – is built around the Atmel-powered Arduino Mega board (ATmega1280) and a number of shields, including Bluetooth, RTC and color LCD.
According to Boris Landoni of OpenElectronics, the goal of Project LEWE is to leverage available tech and create a low cost platform using sensors for data collection.
“Clearly this version is quite hulking, but we wanted to explain how to make the [platform],” said Landoni.
“[Ultimately, everything can be] integrated into a single board or two, in a more compact fashion that can be worn thanks to a special container with a wristband.”
The current iteration of the LEWE prototype currently supports at least five functions, including:
- Measuring body temperature and sweat rate
- Local display of recorded data
- Relaying information to a smartphone app
- Sending and storing data to the cloud
- Organizing data in graph form for analysis
On the app side, LEWE is designed to communicates with an Android smartphone.
“The app consists of a main activity, in which the last data received from the wristband are shown, [along with] a secondary activity that displays the diagram containing all the data,” Landoni added.
“By clicking the icon of the gear, you can enter the app settings [to] connect and configure the cloud access information.”
