Wireless sensor networks project

Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location or sink where

What are the medical applications of wireless sensor networks?

With wireless continuous medical monitoring systems, patients' information such as blood pressure, heart rate, and electrocardiogram can be sent instantly to specialized medical centers to store and process properly.

What are the basic for wireless sensor network?

Wireless Sensor Network (WSN) is an infrastructure-less wireless network that is deployed in a large number of wireless sensors in an ad-hoc manner that is used to monitor the system, physical or environmental conditions.

What are the 4 main types of sensors?

Why we use wireless sensors?

Wireless Sensors allows us to collect information about our surrounding environments with very little manual effort. Devices that use wireless technology are everywhere in the modern world. Wireless sensors can tell you a lot about the condition of your machinery.

Where are wireless sensor networks used?

Such networks are used in industrial and consumer applications, such as industrial process monitoring and control and machine health monitoring. A WSN is built of "nodes" – from a few to hundreds or thousands, where each node is connected to other sensors.

How WSN is used in IoT?

An IoT (Internet of Things) Wireless Sensor Network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring, and recording the physical conditions of the environment, and collectively pass on such data through a wireless network to a internet-based location.

What is WSN architecture?

Wireless sensor networks (WSN) are infrastructure-less and fully distributed systems of self-configurable and self-organized nodes that wish to share the IoT devices' data over the air.

Which topology is used in WSN?

Yain Various topologies are used in WSNs. These topologies include star topology, tree topology, and mesh topology [5] . There are two types of mesh topology; partial mesh topology and fully connect topology [6]. Coverage hole detection is an important research problem in wireless sensor network research community.

Is WiFi a wireless sensor network?

WiFi-based Wireless Sensor Network(WSN) has the features of high bandwidth and rate, non-line-transmission ability, large-scale data collection and high cost-effective, and it has the capability of video monitoring, which can not be realized with ZigBee.

What is the principle of sensor?

The sensing principle of an optical sensor is based on shifts in the characteristic optical signal of an optical platform resulting from interactions with analyte molecules, which are then translated into quantitative and/or qualitative measurements.

What are the advantages of sensors?

The key advantages of sensors include improved sensitivity during data capture, almost lossless transmission, and continuous, real-time analysis. Real-time feedback, and data analytics services ensure that processes are active, and are executed optimally.

How do sensors work?

Put simply, a sensor converts stimuli such as heat, light, sound and motion into electrical signals. These signals are passed through an interface that converts them into a binary code and passes this on to a computer to be processed.

What are the 8 sensors?

The following are the eight key sensors of the car: air flow sensor, intake air temperature sensor, throttle position sensor, water temperature sensor, camshaft position sensor, crank position sensor, knock sensor and oxygen sensor.

What applications use sensors?

There is a multitude of different sensor types, the most popular categories we can offer are; position sensors, pressure sensors, temperature sensors and load and force sensors. Sensors are used in so many applications including motorsport, agriculture, medicine, industrial, aerospace, agriculture and more.

What are the applications of sensors?

Sensors are central to industrial applications being used for process control, monitoring, and safety. Sensors are also central to medicine being used for diagnostics, monitoring, critical care, and public health.

What are the three main uses for wireless?

Here are five uses of a wireless communication system:

Making Calls. On a global level, billions of people have subscriptions for cellular communication.
Connecting Devices. Bluetooth technology allows people to connect various devices. ...
Accessing the Internet. ...
Enhance Security. ...
For Locating and Tracking.

How are sensors used in real life?

Some household appliance applications using sensors are the boiler, washing machines and dishwashers for heating systems, and other white products. Many vehicles, including automobiles, trains, buses, etc., employ sensors to monitor petroleum temperature and pressure, jets and steering systems, and so many more.

When was WSN invented?

The first wireless network that bore any real resemblance to a modern WSN is the Sound Surveillance System (SOSUS), developed by the United States Military in the 1950s to detect and track Soviet submarines. This network used submerged acoustic sensors – hydrophones – distributed in the Atlantic and Pacific oceans.
