A set of sensor nodes cooperating for certain activities is referred to as a WSN (i.e., Wireless Sensor Network). Wireless connections are used by every sensor to transmit data. A sensor node specifically carries out sensing and transmitting tasks. It primarily keeps an eye on environmental factors like sound, temperature, etc. It then sends the info to distant consumers.

The top 7 WSN projects for students to learn from and put their talents to the test are as follows:

1. Low power Smart Vehicle Tracking, Monitoring, Collision avoidance and Antitheft System

By aiding with Fleet Management, Vehicle Security, and Safety, this project offers a system that effectively and efficiently delivers an Internet of Things application in the transportation industry. Technology only succeeds when it reaches every socioeconomic level.

This article proposes a vehicle tracking and anti-theft system that operates just utilising GSM-GPS and open source technology, making it the cheapest solution for Fleet Management, safety, and security in comparison to the several pricey GPS tracking systems that are currently on the market.

Your research career will be intelligently monitored and reshaped by Wireless Sensor Network Projects. The basic processes in WSNs like network construction, sensing, data transmission is important for the implementation in projects for solving real life problems and also for the success of the project.

2. Design and Application of Intelligent Agriculture Service System with LoRa-based on Wireless Sensor Network

Based on LoRa wireless technology, this project suggests a low-power agricultural environment detecting system. ZigBee, Wi-Fi, and GPRS traditional wireless sensing technology has a short transmission distance and signal interference in greenhouse environment monitoring systems such as large farms. This is due to the current intelligent agriculture's collection and processing of production site data and the control requirements of related equipment.

To fully identify soil, model environmental conditions, regulate lighting, irrigation, cooling, and man-machine interfaces, this model may make use of numerous sensors in the lab.

3. Arduino Based traffic congestion control with automatic signal clearance for emergency vehicles and Stolen Vehicle Detection

The traditional traffic signal system is based on a set time concept that is assigned to either side of the junction and cannot be adjusted to account for changes in traffic density. When there are more cars waiting on the same route, the priority of the traffic signal has to be adjusted. When the junction's traffic density is detected, the signal automatically adjusts.

IR sensors and Arduino RFID were used to create the prototype model. Due to its simplicity and affordability, we utilise Arduino to build code that meets our criteria, and IR sensors are used to measure the volume of traffic on a certain road. There may be restrictions on the ability of IR sensors to function in normal lighting. As a result, traffic lights function incorrectly.

4. Energy-Efficient Resource Allocation in Wireless Energy Harvesting Sensor Networks

The energy harvesting in WSN is the major focus of this research. Recently, an approach to solve the aforementioned issue has been presented using EH (i.e., Energy Harvesting) sensors. These sensors' extended lifespans are the consequence of their ability to capture the energy they need from the environment in various ways.

We investigate a WEHSN (i.e., Wireless Energy Harvesting Sensor Network) based on TDMA, where the time slot is comprised of two-time intervals. Energy is absorbed in the first-time interval whereas the data is transmitted from the sensors in the second time interval.

5. Smart Door Using Biometric NFC Band and OTP Based Methods

With the use of biometric, NFC band, and OTP authentication mechanisms, this concept provides a novel design for a smart door that would enable safe and convenient entrance to our homes.

By lowering the time required for authentication using a biometric fingerprint sensor and adding an additional layer of security by employing a local server to create OTP authentication, our approach offers the chance to address the problems these systems encounter. Compared to previous methodologies, this implementation has produced better outcomes and a greater performance rate.

6. Energy-Neutral Wireless Sensor Network Based on SWIPT in Wireless Powered Communication Networks

A unique ENO framework is provided in this work. A WSN deployed in a wireless powered communication network is taken into consideration for ENO (i.e., Energy-Neutral Operation) of WSN (i.e., Wireless Sensor Networks).

In this network, sensor nodes with excellent energy harvesting and strong connection budgets still have energy after transmitting their data to the cluster head (CH), but the CH experiences energy shortage.

As a result, the work employs the SWIPT (i.e., Simultaneous Wireless Information and Power Transfer) approach so that the sensor nodes may cooperatively send data while transferring their remaining energy to the CH.

7. Real-time Wireless Embedded Electronics for Soldier Security

As part of this project, we have described how to use GPS to track a soldier’s location. We will also be able to keep an eye on vital signs like body temperature and heart rate. In order to inform the control centre of the soldier’s status, the measured parameters will be transferred there with the aid of a GSM module.

When a soldier is hurt, the variations in their heartbeat and pulse rate are recorded, which alerts the military base station and allows us to find them using GPS.

With the help of this data, we can organise the next battle with an accurate count of soldiers who are unhurt while simultaneously supplying the injured soldier with the necessary medical care thanks to the GPS position.
