Wireless sensor networks (WSN) allow for the collection and transmission of data from various sensors distributed across an area. A WSN consists of sensor nodes that communicate wirelessly to monitor things like environmental conditions, industrial processes, and infrastructure. They have advantages like low cost, easy deployment, long-term operation, fault tolerance, and wide applicability. LINTECH develops both the hardware and software for WSN, using standards like Zigbee, to enable monitoring in various fields such as utilities, transportation, construction, healthcare, and more. WSN provide a cost-effective solution for distributed data collection and monitoring across many industries.

implementation of hardware and software of wireless sensor
networks (WSN), which allows economically to solve a wide
range of engineering, industrial and domestic problems of
modern life.
The company's mission
“Introduction of “smart dust” will make the world a safer,
more secure and more environmentally.”

5. Wireless sensor networks
This device is capable to organize itself in ad-hoc network on
given architecture and to execute distributed accounting, GRID
computing

6. The main function of wireless sensor
network (WSN)
The main function of WSN is the solution of
problems of collecting, information processing and
transmission with high demands for autonomy,
reliability, scalability, and distributed network.

7. Advantages of systems based on sensor
networks
- promptness and economy of deployment;
- there is no need in service;
- extended autonomous operation;
- advanced fault tolerance and reliability under
severe operating conditions;
- wide field of application.

8. The technology of sensor networks.
Composition of WSN.
DSN consists of hardware and software.
Zigbee IEEE 802.15.4 standard.
WSN are protected by original algorithms and software.

9. The hardware of WSN
WSN hardware are:
• endpoints (nodes of networks) for
collection parameters;
• routers;
• coordinator of the Network;
• gateway that has a radio transceiver and
united in a networked.
Hardware base is commercially available.

10. The structure node of
WSN
One node consists of:
- microchip;
- RF-transmitter;
- sensor;
- battery.

11. The software part of WSN
The software, based on the original
algorithms, which are protected by
copyright:
- to control, data collection and
transmission;
- to visualize the results.
OS: TinyOS, Linux, Win.
Programming language: C, Java.
Сompiler gcc

12. Zigbee IEEE 802.15.4 standard
Standard IEEE 802.15.4, also known as ZigBee, is a
low-speed connection standard intended for low-power,
short-range communication between wireless devices. In
addition, radioequipment ZigBee must have an extremely low
power consumption, and must work for years without
replacement of power sources.

13. Characteristics of the sensor
The network topology
The options: 1) Star, 2) Tree, 3) Mixed, multi-cell
Mode of operation of the
nodes
The options: 1) Continuous, 2) sleep on a schedule 3)

emergency.

17. Problems of the modern industrial and
environmental monitoring (if using wired
connection)
Installation of wires requires
the development of the project,

exceeds the value of laying new
cables!

the network performs its functions;
Can be added or removed any number of devices from the network;

High level of penetration through obstacles (walls, ceilings) and resistance to
electromagnetic interference (unlike wi-fi);

Long operating time without battery replacement due to budget conscious microchips
and algorithms developed in the framework of the project;


