With the advent of time, science and technologies are become diversified in nature. In order to investigate the vastly unexplored oceans that cover most of our planet, professionals of Computer Science Engineering at B Tech Colleges aim to build a submerged network of interconnected sensors. It sends data to the surface which is an underwater “internet of things.”
Top Engineering Colleges in Rajasthan has introduced a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system uses to monitor sea temperatures to study climate change and track marine life over long periods. It also works on sample waters on distant planets.
The system uses two key phenomena by the students of the Best Engineering Colleges in Rajasthan, One, called the “piezoelectric effect,” occurs when vibrations in certain materials generate an electrical charge. The other is “backscatter,” a communication technique commonly used for RFID tags that transmits data by reflecting modulated wireless signals off a tag and back to a reader.
In this system, a transmitter sends acoustic waves through the water toward a piezoelectric sensor having stored data. When the wave hits the sensor, the material vibrates and stores the resulting electrical charge into it. Then, the sensors make use of the stored energy to reflect a wave back to a receiver.
Once students of Computer Science Engineering at B Tech College in Jaipur have a way to transmit 1s and 0s, they can send any information. It enables communication with underwater sensors solely on the incoming sound signals whose energy is harvested.
Students of Top 10 Engineering Colleges in Jaipur have found that an individual cannot use Wi-Fi or Bluetooth signals for underwater exploration. Putting batteries all over the ocean can raise several issues with pollution.
Communication relies on preventing the piezoelectric resonator from naturally deforming in response to strain. At the heart of the system is a submerged node, a circuit board that houses a piezoelectric resonator, a microcontroller, and an energy-harvesting unit. Any type of sensor can integrate into the node by programming the microcontroller by the students of Arya College.
The transmitter and receiver must have power but can be planted on ships or buoys. In this, batteries are easier to replace, or connected to outlets on land. One transmitter and one receiver can easily gather information from many different sensors covering one area or many areas.
Another interesting application is monitoring brine pools, large areas of brine that sit in pools in ocean basins. They are difficult to monitor for the long-term. You can sense what is happening down there, without needing to keep hauling sensors up when their batteries die.
The system still needs more experimentation, especially in seawater. This might be the ultimate solution for the experts of Engineering Colleges in Jaipur in marine biography, oceanography, or even meteorology.
