FlatMesh™

The award winning FlatMesh™ platform uses a wireless mesh-networked, intelligent sensor system consisting of a collection of small easy to deploy devices, equipped with sensing, communication and computation capabilities. They work co-operatively and intelligently (“they talk to each other”) to enable monitoring of complex layouts or challenging and difficult to access environments.

The FlatMesh™ platform development was part funded by the Technology Strategy Board who recognised Senceive’s leadership in the global wireless market for geotechnical sensing.

Wireless Mesh Networking

At a technical level the system has been tested and proven over a decade of deployments in highly demanding environments, and prior to that 5 years of research at UCL, one of the world’s pre-eminent engineering universities. Our System Integration Layer consists of a lightweight operating system and modules that interface between the sensors, communication layers and processing systems on each node and then back through a gateway to our server and web interface.

The nodes themselves are micro-controller based, wireless mesh-networked based on IEEE 802.15.4 and form an integrated system that can monitor over a wide area, or any convoluted physical/geographical environment. Working as a self-configuring wireless mesh, data moves from neighbour to neighbour through the network. This provides an extremely robust and flexible solution adaptable to many various and challenging situations.

As a result of many years of development on sensor interface and wireless algorithms, battery life is unrivalled and should last between 12 to 15 years in typical situations of 15 minute to one hourly reporting.

Proprietary algorithms support functions such as clustering, data retrieval and policy distribution, self-diagnosis, dynamic algorithm management and security models. Nodes communicate with the gateway in order for data to exit the system. The gateway only needs to communicate with one node in order for the whole network to send data. This provides for highly flexible deployment configurations, particularly in comparison to hub and spoke wireless alternatives.

Senceive’s gateways comes in a variety of options to ensure data is readily available even before the install team leaves site. The options vary from USB connection to a laptop or industrial PC, connectivity via a solar powered cellular gateway or to a wide choice of networks where some power is available and connections to other data bases, data loggers or industrial PC’s are appropriate. The system is highly intelligent and enables us to interact with nodes and the gateway remotely; via the web it is possible to visualise and manage key elements within the network.

Data is transmitted to our user friendly WebMonitor software or can be sent to customer defined alternative software. Read more about the WebMonitor here.

While our proprietary technology is exciting and we are innovating continuously, we only bring the most robust and applicable products and techniques to market.
