SenzaBlock

How many SenzaBlocks can be interconnected into a network?

What types of sensors can be used with a SenzaBlock?

What is SenzaNET? ⇑

E-Senza Technologies developed SenzaNET as a unique technique to support in best conditions a wireless device network. SenzaNET is based on the IEEE 802.15.4 low-power wireless standard.

How does SenzaNET compares to other wireless standards? ⇑

WLAN and Bluetooth are standards meant for high-data rate, like multimedia videos, pictures and voice. Moreover the power consumption is very high and the range reduced.
RFID is a passive RF barcode with no intelligence, no active communication channels and very small transmission power only in the neighborhood of the reader.
From the wireless standards ZigBee is most similar to SenzaNET, since it is based also on IEEE 15.4, with the difference that SenzaNet has smaller footprint, higher range, longer battery life and a high-level Java API.

SenzaNET range capability is up to 600 mt LoS depending on frequency band and power used. SenzaNET is used mostly for text/measuring data and transmits in 2,4 Ghz frequency channel.

How easy is it to integrate SenzaNET devices into an existing application? ⇑

The monitoring solutions provided by E-Senza are plug-and-play configurable systems.

The server application is based on Java and therefore it is platform independent and easily integratable into a multitude of systems.
At the sensor level, SenzaBlocks are also provided with multiple interfaces and can integrate most of the typical devices worldwide.
SenzaGate allows most of the possible connections like: RS232, RS485, Ethernet, GPRS, USB, Wi-Fi

Is it possible to add SenzaNET technology to existing appliances and other devices? ⇑

Yes, SenzaNet can be easily integrated with new devices and therefore ideally used in retrofitting actual systems.

What are the features of the application interface? ⇑

The server application is based on Java and it is platform independent and easily integratable into a multitude of systems. With the server application the customer can get a multitude of tools like statistic, report, graph, data management, network console module etc.

What is a wireless sensor network? ⇑

A Wireless Sensor Network (WSN) is an exciting new technology that allows for networking of small sensor nodes communicating wireless among themselves. Unique characteristics of a WSN are:

Limited power they can harvest or store
Harsh environmental conditions
Node failures
Mobility of nodes
Dynamic network topology
Communication failures
Heterogeneity of nodes
Large scale of deployment
Unattended operation

E-Senza evolved this term to include any measurement device. E-Senza develops systems based on wireless device networks (WDN), which allow at the same time sensing, control and interaction.

What frequencies are used in the radio communication? ⇑

SenzaNET uses license-free frequency spectrum of 2.4 GHz.

What are some examples of low-power wireless networks? ⇑

Low-power wireless networks can be used for a variety of temperature monitoring applications like greenhouse, data center, warehouse and cold chain monitoring.

In buildings in order to centralize data collection from fire alarms, security access or temperature room monitoring etc.

Monitoring and control of industrial parameters can become very much flexible when it is supported by multiple tiny flexible wireless nodes.

Even meters can be read remotely and integrated with customer systems without any manual intervention by help of wireless device networks.

What are SenzaBlocks? ⇑

SenzaBlocks are the wireless network elements which can be integrated with almost any sensor or device in order to collect data and control the device remotely.

SenzaBlocks can be imagined as intelligent and independent mini-computers with wireless capabilities. They usually consume very little power and can operate for years with a single battery and without any attendance.

They are available with interfaces for analog, digital and puls signals. SenzaBlocks can also be provided with integrated sensors for measuring temperature, level, humidity, energy, light etc.

How many SenzaBlocks can be interconnected into a network? ⇑

Usually 32 SenzaBlocks can be connected to a SenzaGate.
At the same time 256 SenzaGates can be built up to a big network containing 256 x 256 nodes.
Yet there can be restrictions in range, power and costs which have to be taken into consideration.

What types of sensors can be used with a SenzaBlock? ⇑

Theoretically, any sensor can be integrated with SenzaBlock. Since SenzaBlock is meant to be universally integratable it provides following interfaces: Analog I/O, CS Meter, 4-20 mA I/P, Digital I/O, Serial

Typical devices which can be interfaced are:
