e-Health Biometric Sensor Platform for Arduino and Raspberry Pi

luis_conectado-smallThe new e-Health Biometric Sensor Platform developed by Cooking Hacks (the open hardware division of Libelium) allows Arduino and Raspberry Pi users to perform biometric and medical applications where body monitoring is needed by using 9 different sensors: pulse, oxygen in blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG), glucometer, galvanic skin response (GSR – sweating), blood pressure (sphygmomanometer) and patient position (accelerometer). 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: Wi-Fi, 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.

GreenPeak launches the GP710: the first dual-protocol ZigBee chip

The dual ZigBee network solution for Set-Top Box and Gateway combines ZigBee RF4CE and ZigBee IP/ZigBee PRO for Smart Home Solutions

GreenPeak Technologies, a leading Smart Home RF-communication semiconductor company, today announced the launch of the new GP710, a dual-protocol ZigBee communications controller with simultaneous support for ZigBee RF4CE and ZigBee IP/ZigBee PRO protocols.

The GP710 communication controller is targeted for set-top boxes, gateways and Smart Home controllers and designed for supporting simultaneously ZigBee RF4CE applications – such as remote controls – as well as ZigBee IP or ZigBee PRO Smart Home applications such as security, home care and energy management.

The benefits of this GreenPeak dual-protocol communication chip are much simpler product design, cost reduction of the total product bill-of-material (single silicon) and a less complex PCB and antenna that makes it simpler and faster for developers to integrate ZigBee into their set-top box or gateway designs.

“The GP710 provides a low cost solution that combines different ZigBee Network protocols into a single chip,” said Cees Links, Founder and CEO of GreenPeak Technologies. “GreenPeak has developed special hardware features to enable multi-protocol support, minimizing the interrupt load on the set-top box processor, and allowing simultaneous RF4CE and other ZigBee protocol operations. This is a first for the industry! Because of GreenPeak’s superior range that covers the whole home and its ultra-low power consumption for long battery life, the GP710 is the best in class choice for integrated low cost Smart Home ZigBee applications.”

Cees Links continues: “Many large operators already support ZigBee RF4CE in the set-top box and remote controls and have an urgent need to broaden the service offering to their customers. GreenPeak’s GP710 communications controller will make new Smart Home service offerings less expensive because new residential applications can all be controlled from the set-top box or gateway using a single device.”

“This solution leverages the growing availability of ZigBee RF4CE in the market,” said Tom Kerber, Director, Research, Home Controls & Energy, Parks Associates. “Adding ZigBee IP/ZigBee Pro to the ZigBee RF4CE silicon will make it easy for service providers already using ZigBee RF4CE remote controls to add home automation devices – now an area of significant focus by communications service providers.”

The new radio module extends Waspmote features allowing the sensor data to be used in asset tracking, supply chain monitoring, intelligent shopping or access management. Read more.

Zigduinos for Sale

The Zigduino is a pin and code compatible OSHW Arduino variant based around the ATmega128RFA1. This gives it a number of useful features above and beyond a stock Arduino:

Built-in 802.15.4 transceiver
Hardware AES-256 encryption module
128K of flash
16K of RAM
In order to improve the Zigduino’s durability for field sensor applicaions and provide full shield compatibility, all pins are protected by diodes and series resistors capable of absorbing spikes of ±30V. It can handle an input voltage range of 6V-30V with power supply spikes to -20V and +60V.

The Zigduino ships as a kit. Each kit includes:

– A bare Zigduino board
– Female headers for the standard Arduino pinout as well as the separate I2C and SPI connectors.
– One male 2×3 pin header for the programming port
– A 2.1mm DC barrel jack for power
– A card-edge RPSMA RF connector
– A 2dBi antenna.

The Zigduino is now on sale for $69.99! It is shipping worldwide and available for retail purchase at Metrix: Create Space. It will shortly be available from Seeedstudio and lipoly.de.

ZigBee Alliance Establishes Chinese Offices

The ZigBee Alliance, a global ecosystem of organizations creating wireless solutions for use in energy management, residential, commercial and consumer applications, today announced it has opened two new offices in China to drive greater ZigBee adoption and address ZigBee standards to meet China’s specific needs for its rapidly expanding infrastructure and growing markets.

The Alliance appointed Jerry Huang as director of ZigBee Asia Pacific, Greater China representative, with offices in the Sensing China Center in Wuxi and in Zhongguancun Science Park (Z-Park) in Beijing. Huang, who has 20 years of marketing experience, will lead the Alliance’s collaboration on the Internet of Things industry efforts and standards development from these offices.

“ZigBee is very excited to have a local presence in China,” said Bob Heile, chairman of the Alliance. “China has declared the Internet of Things to be one of three strategic imperatives in its current five year plan and ZigBee’s comprehensive global standards for wireless sensor networks are key enablers for the IoT. Our two office locations will help us expand and deepen our collaboration with China in achieving this important objective.”

The Chinese Sensing China Center, located in Wuxi, is a thriving center of excellence on the Internet of Things. The Z-Park is one of the largest high-tech parks in China, located in the heart of the Chinese Capital City. Traditionally, many national and highly influential technology projects have initiated at Z-Park.

What’s Driving The Success Of IEEE 802.15.4 Radios?

Since its 2003 release, the IEEE 802.15.4 radio has become hugely popular for wireless sensor and actuator networks (WSANs), and it is the underlying radio standard for protocols such as ZigBee, 6LoWPAN, and WirelessHART. This growth can be attributed to its availability as an inexpensive standard IC. It’s also sophisticated yet reasonably easy to use.

The IEEE 802.15.4 radio is a short-range, multichannel, spread-spectrum radio designed to support large, low-power, low-data-rate mesh networks. The standard and ZigBee are often, and improperly, considered synonyms of one another. Therefore, it’s important to understand the clear separation of functions implemented in the radio from those managed in the upper protocol layers.

The 802.15.14 standard only specifies the lowest two layers of the protocol stack—the physical layer (PHY) and medium access control (MAC) layer. The upper layers of the protocol are separately defined by various interests according to their specific application needs. Of these, the largest and best known is the ZigBee Alliance. However, myriad proprietary protocols are also in use today, and they all rely on 802.15.4 as their underlying radio standard.
