In August 2013 Cooking Hacks launched the new version of the first biometric shield for Arduino and Raspberry Pi: the e­Health Sensor
Platform V2.0. Thanks to the feedback given by the Community and several projects that have been created with it, we have improved the e­
Health platform with new features such as:
New muscle sensor
New blood pressure sensor
Upgraded glucometer
New Connection possibilities
In this tutorial we will explain how to work with e­Health Sensor Platform V2.0. If you have e­Health V1 you can see how to use it on this link:

(/media/cooking/images/documentation/e_health_v2/e_health_top_big.png) The e­Health
Sensor Shield V2.0 allows Arduino and Raspberry Pi users to perform biometric and medical
applications where body monitoring is needed by using 10 different sensors: pulse, oxygen
in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG),
glucometer, galvanic skin response (GSR ­ sweating), blood pressure
(sphygmomanometer), patient position (accelerometer) and muscle/eletromyography sensor
(EMG).
This information can be used to monitor in real time the state of a patient or to get sensitive
data in order to be subsequently analysed for medical diagnosis. Biometric information
gathered can be wirelessly sent using any of the 6 connectivity options available: Wi­Fi, 3G,
GPRS, Bluetooth, 802.15.4 and ZigBee depending on the application.
If real time image diagnosis is needed a camera can be attached to the 3G module in order to send photos and videos of the patient to a medical
diagnosis center.
Data can be sent to the Cloud in order to perform permanent storage or visualized in real time by sending the data directly to a laptop or
Smartphone. iPhone and Android applications have been designed in order to easily see the patient's information.
(/media/cooking/images/documentation/e_health_v2/e_health_sensors_big.png)  Quick FAQ
What does it mean to count with an open medical monitoring platform?
Cooking Hacks wants to give Community the necessary tools in order to develop new e­Health applications and products. We want Arduino and
Raspberry Pi Community to use this platform as a quick proof of concept and the basis of a new era of open source medical products.
How do I ensure the privacy of the biometric data sent?
Privacy is one of the key points in this kind of applications. For this reason the platform includes several security levels:
In the communication link layer: AES 128 for 802.14.5 / ZigBee and WPA2 for Wifi.
In the application layer: by using the HTTPS (secure) protocol we ensure a point to point security tunnel between each sensor node and

IMPORTANT: The e­Health Sensor Platform has been designed by Cooking Hacks (the open hardware division of Libelium) in order to help
researchers, developers and artists to measure biometric sensor data for experimentation, fun and test purposes. Cooking Hacks provides a
cheap and open alternative compared with the proprietary and price prohibitive medical market solutions. However, as the platform does not
have medical certifications it can not be used to monitor critical patients who need accurate medical monitoring or those whose conditions must
be accurately measured for an ulterior professional diagnosis.
