Wireless Sensor Network connecting IoT Devices
Wireless Sensor Network (WSN) is an infrastructure-less wireless network that is used for deploying a large number of wireless sensors that monitor the system, physical and environmental conditions. Our extremely motivated and professional engineers are very well equipped to provide you with an all round solution if you are looking to incorporate WSN in your business.
Networks connecting Wireless Sensors
To connect Sensors embedded in IoT devices, a communication protocol is used. A low-power wide-area network ,LPWAN, is a type of wireless network designed to allow long-range communications between these IoT devices.Lora based Wireless Sensor network is widely used. Sub-1 GHz, Zigbee,Thread etc are also used to connect sensor networks and gateway and data collected from this sensor network can be sent to cloud using cellular networks such as NBIoT, LTE-M or wifi etc.
Components of Wireless Sensor Network
Sensors- Sensors play the vital role of capturing environmental variables. The data that is captured is converted into electrical signals for transmission.
Radio Nodes- Radio nodes in Wireless sensor network receive data from the sensors and forward it to the gateway. These consist of microcontrollers, transceivers and a battery.
Access Point or Gateway-It is used to receive the data sent by the radio nodes wirelessly typically through the internet or other cellular network and send it over the cloud.
Edge Computing and Data Analysis-The data received by gateway is further processed, analysed and stored. This data can be displayed on IoT mobile application or IoT dashboard.
Applications of WireLess Sensor Network

Wireless Sensor networks by PsiBorg
- Fault Tolerance – Fault tolerance is the ability of the network to work even when there is a break due to sensor node failures. These kinds of unanticipated failures occur from time to time in networks.
- Mobility of Nodes – Nodes can be moved anywhere within the sensor field in order to increase the efficiency of the network.
- Scalability – WSN is designed in such a way that it can have thousands of nodes in a network. Hence, it is highly scalable.
- Feedback in case of Communication Failure – If a particular node fails to exchange data over the network, it informs the base station immediately without any delay.
With our expertise in the field we assure you to provide you with impeccable solutions for all your needs.
What is Wireless Sensor Network or WSN in IoT?
Wireless Sensor Network (WSN)is deployed in a large area with a large number of wireless sensors nodes in an ad-hoc manner that is used to monitor the system, physical or environmental conditions. The data is then sent to gateway for processing or edge computing.
What are the communication protocols on which Wireless sensor networks communicate?
The sensor nodes are connected over Low Power Wide Area Network (LoRaWAN, Sub-1Ghz, ZigBee, Sigfox etc) which is used to connect sensor Nodes to the gateway unit. The gateway unit is connected to the internet (consisting of Cellular or WiFi Module) from where the processed or edge computed data which is further sent to the server or Cloud.
What is the IoT gateway in Wireless Sensor Network?
The Gateway acts as a bridge between the Wireless Sensor Network and cloud. IoT Gateways manage device connectivity, data filtering, processing, protocol translation, security etc. Adding a cellular module (works on LTE, NBIoT, LTE-catM1, etc) or an Internet modem (works on WiFi) to the gateway makes the WSN remotely managed.
How does a wireless sensor network work?
The sensor nodes used in Wireless Sensor network systems are integrated with the onboard controllers. The complete circuitry manages the operation and monitors it mainly. Everything is connected with the base station known as the Gateway, where high end processing of data collected from distributed sensors is done. The data is further sent to cloud for storage and analysis, and this data is fetched by a mobile or a cloud application. All the distributed sensors devices in WSN are mostly connected over a LPWAN and communicate with the gateway.
