1. Wireless Sensor Network, Wsn

1.1. What is a Wireless Sensor Network?

There are a number of definitions of wireless sensor networks, and a few more common ones are listed: Wireless sensor network is deployed in the monitoring area by a large number of quality and cheap micro-sensor nodes, It is formed by wireless communication of a multi-hop self-organized dynamic network system, The purpose is to collaboratively track, perceive, collect and process information about the perceived objects in the network coverage area, and sent to the data center, in order to carry out information processing.

Wireless sensor network is based on sensor detectors, wireless communications and computer applications and other science and technology to build the target monitoring system (Han, We, Zhang, Zhang,2005).

1.2. Wireless Sensor Classification

Generally used classification:

According to the measured parameters classification: temperature, pressure, displacement, speed and so on.

According to the working principle classification: strain type, capacitive, piezoelectric, magnetic and so on.

Functional materials classified as sensitive components: semiconductor sensors, ceramic sensors, fiber optic sensors, polymer membrane sensors, etc.

Combined with a technology name: integrated sensors, smart sensors, robot sensors, bionic sensors.

1.3. Basic Features

Large-scale network, self-organizing network, multi-hop routing, dynamic network, data-centric network, application-related network.

1.4. Requirements for Use

  • Sufficient capacity

  • High sensitivity, accurate accuracy

  • Fast response, stable operation, high reliability

  • Applicability and adaptability

  • Use the economy

1.5. Sensor Composition

Sensitive components: direct feelings are measured, and to determine the relationship between the output of a physical quantity.

Sensing element: the non-electrical physical output of the sensitive components into the number of circuits or power.

Basic conversion circuit: the circuit parameters will be converted with the measured power.

1.6. In the Application of Smart Home

Personalized entertainment, safety management, disaster management, environmental control, identification and positioning, health management.

1.7. Sensors Used in Smart Homes

Thermal infrared detector, microwave object motion detector, infrared microwave probe, door switch, glass break detector, ultrasonic object motion detector, infrared probe, smoke alarm probe.
