400MHz RF transceiver geared for wireless smart energy apps

400MHz RF transceiver geared for wireless smart energy apps

A*STAR Institute of Microelectronics (IME) and Cubic Micro have developed and demonstrated a 400MHz radio frequency (RF) transceiver that claims to offer the highest power efficiency to deliver high quality signals over the industry’s widest coverage in wireless sensor network applications.

The transceiver is integrated with a highly configurable base band that enables users to customise transceiver performance for specific applications ranging from wireless smart energy management and security control in homes and buildings to long-range remote industrial monitoring.

To achieve low power consumption in RF transceiver, performance is typically sacrificed, resulting in degradations of sensitivity, channel selectivity and interference immunity during the wireless signal communication process.

Smart Water Sensors to monitor water quality in rivers, lakes and the sea | Libelium

Libelium launched a Smart Water wireless sensor platform to simplify remote water quality monitoring. Equipped with multiple sensors that measure a dozen of the most relevant water quality parameters, Waspmote Smart Water is the first water quality-sensing platform to feature autonomous nodes that connect to the Cloud for real-time water control. Waspmote Smart Water is suitable for potable water monitoring, chemical leakage detection in rivers, remote measurement of swimming pools and spas, and levels of seawater pollution. The water quality parameters measured include pH, dissolved oxygen (DO), oxidation-reduction potential (ORP), conductivity (salinity), temperature and dissolved ions (Na+, Ca+, F-, Cl, Br-, I-, Cu2+, K+, Mg2+, NO3-).

The Waspmote Smart Water platform is an ultra low-power sensor node designed for use in rugged environments and deployment in Smart Cities in hard-to-access locations to detect changes and potential risk to public health in real time.

Novel sensor system would flag structural weaknesses before bridges and stadiums collapse

NJIT will be part of an international team of engineers from universities in the U.S., Canada, and Qatar developing a novel system to detect the onset of structural damage on bridges, stadiums and other large public infrastructure.

With a grant of just over $1 million from the government of Qatar, a Persian Gulf nation that has proposed building one of the longest causeways in the world, the three-member team is developing a wireless sensor network that will monitor vibrations, sagging and stresses to assess a structure’s ability to carry its load. The proposed system would not only detect damage after it occurs, but would aim to predict it before it takes place.

“Our part of this project is to determine not only where to place the sensors, but to decide what type of data the system will collect, how to interpret it, and then how to make a decision about where, when, and to what extent to intervene,” said Mohamed Mahgoub, director of NJIT’s Concrete Industry Management (CIM) program and one of the project’s principal investigators.

The system would alert bridge engineers in real-time to potentially catastrophic structural failures or weaknesses, while also guiding periodic preventive maintenance.

“While the network can be installed on existing bridges, the aim is to embed it in a structure’s steel bars before the concrete is even poured,” Mahgoub said.

Thingsquare’s Contiki IoT workshop slides posted

From The Official Contiki OS Blog:

The first set of slides from the Thingsquare Contiki IoT workshop series have been posted.

The slides show how to connect a Contiki system to the Internet and make it interact with web services, how to build an IoT cloud service with node.js and Javascript, some of the next steps for Contiki 3.x, and some of the trade-offs in choosing a communication technology for your next IoT system. Slides for the three remaining days will be posted during the week.

STMicroelectronics launches mbed-enabled family with NUCLEO

stm32-nucleoFrom mbed blog:

Just today STMicroelectronics (STMicro) announced their new line of STM32 mbed-enabled development boards, the STM32 Nucleo!

This will be a full line covering the STM32 Microcontrollers, and of course the really great thing is ST developers will now have access to mbed’s ecosystem of software, tools, and community!

The Nucleo boards will allow developers to re-use hardware and software IP for multiple projects and create scalability for their STM32 designs, as they are all going to be the same form factor and software platform. This will also offer a wide variety of shields supporting functions such as Bluetooth® LE or Wi-Fi connectivity, GPS, audio recording utilizing STMicro’s MEMS microphone capability, proximity sensing, and wireless control.

This is a great line, and we are looking forward to seeing the wider range of prototypes and innovations that come from the addition of the STM32 Nucleo family.

And if you are wondering, the first four boards will be released at Embedded World next week at $10.32 per unit!
