As the electronics industry and user needs are developing rapidly, the design of embedded systems should match their standards. Every equipment we encounter with our day-to-day life is getting automated, the world is getting smarter day by day. As the usage of sensors is increasing, the processor should be capable of handling an enormous amount of data. Our work will focus on designing and implementing an FPGA (Field Programmable Gate Array) based DAQ (Data Acquisition) system. Sensors and FPGA both are independent research areas, their combination is an emerging research area. The prime reason to choose FPGA over other MCUs (Micro-controller units) is the top processing speed. The system mainly includes sensors, a DAQ device, and signal processing (Denoising). Noise affects real-time systems. Noise is random and unpredictable, so noise reduction processing is necessary to get an accurate measurement. Denoising algorithms are very complex, so FPGAs are better than MCUs. The proposed system fetches the real-time signals from sensors, performs the digitization, and the digitized data can process accordingly. We observe it that only a few works are available for real-time applications.

Ullas S. and Vishwas, H. N., “Flow Management and Quality Monitoring of Water using Internet of Things”, in 2019 International Conference on Smart Systems and Inventive Technology (ICSSIT), Tirunelveli, India, 2019.[Abstract]


This paper lays an emphasis on the efficient use of water by mankind, quality monitoring of water and provides a simple solution to the problem through of Internet of Things (IoT) technologies. The increase in demand for groundwater and mankind's careless usage without knowing the recharging capacities of the aquifers has resulted in the present situation. As the availability of groundwater is varied across different regions of the country, it is imminent for a system that can measure the amount of water we use in our day-to-day activities. In addition to the amount of water we use, it is also important that we consume water which is free of impurities. This work has produced a plug and play device that can effectively monitor the water used in our daily activities and its quality.

Aquaculture termed in the manner that fish or crustacean farming deals with the breeding, rearing and production of water plants and organisms. Numerous real water parameters influence the yield of aquaculture result. This paper aims at the implementation of an automated aquaculture farm. The proposed system gathers the data such as the water pH, level, temperature and it execute suitable variations in the water habitat at appropriate times in the absence of human mediation. This system will inform the farmer as pH of water exceeds maximum threshold or if it reduces under the minimal threshold.

R. S. Ranjith, Vishwas, H. N., S.S., M., V.R., H., and S.K., N., “Analysis study of data buffer policies in a fuzzy logic based WSN using cluster head”, in Proceedings of the 2017 International Conference On Smart Technology for Smart Nation, SmartTechCon 2017, 2018, pp. 846-851.[Abstract]


The Wireless sensor network has emerged as the new technology that will have a profound effect in all the fields being wireless in nature. Sensors are tiny nodes which have power constraints as a challenge. In this paper, we decide to conserve the energy and avoid the congestion of packets, so we have to find a route for transmission, so two cluster heads are used i.e. Secondary cluster head (SCH) and Primary cluster head (PCH) which will act as the carrier of data till the base station. One Secondary CH is chosen using fuzzy logic with the inputs which are-remaining battery, distance from node to base station and the speed of the nodes, whereas for each cluster one PCH is selected based on the distance from the center. Thus a route is found out with the SCH and PCH in the route thus conserving the energy of the nodes. The data packet delivery process is also shown in this paper with the help of two buffer policies. As each node has data packets which has different priorities (High priority & Low priority) thus the packets are being delivered by the nodes in the route also apart from the initiator, the number of type of packets to be transmitted by the nodes in the route is decided with two buffer policies, which is Single Buffer policy and Dual Buffer policy. Both the policies are analyzed and studied for a number of iterations. © 2017 IEEE.

R. Sara Ranjith and Vishwas, H. N., “Evaluation study of secondary cluster head selection using fuzzy logic in WSN for conservation of battery energy”, in 2017 International Conference on Inventive Communication and Computational Technologies (ICICCT), Coimbatore, India, 2017.[Abstract]


The coming generations are using the wireless sensors, and all of these networks have been deployed across various areas. Also they are used with the real time systems thus catering to the needs of the present scenario which the traditional methods have failed. These wireless networks deploy sensors around the area, but the disadvantage lies that these sensors have very limited battery life, so to use it in an efficient way conserving the battery power, 2 cluster heads are chosen called the secondary cluster head(SCH) and primary cluster head, SCH which is selected based on three factors namely, the remaining battery power, speed and centrality and fuzzy logic is been applied on these three factors to select the super cluster head. The primary cluster heads are chosen for each cluster based on the centrality distance. In this paper the cluster formation, selection of primary and super cluster head is analyzed and the network is simulated and measured with the parameters like end-end delay, Number of hops, Residual Energy, number of alive and dead nodes and energy consumption.

Efficient power consumption and no power wastage is as good as generation extra power. In bit dark areas like parking lots or stock yards, etc huge amount of electricity is wasted because of unnecessary use of lights throughout the day and night. This paper describes an energy-efficient lighting system for underground and indoor parking lots. This system enables the lights to be used only when required and to be turned off otherwise. It uses Zigbee protocol for data transmission, and PIR i.e. Passive Infrared sensors for motion detection.

V. Kodire, Bhaskaran, S., and Vishwas, H. N., “GPS and ZigBee based traffic signal preemption”, in Proceedings of the International Conference on Inventive Computation Technologies, ICICT 2016, 2017, vol. 2.[Abstract]


It is very unsafe for Emergency Vehicle (EV) to wait near the traffic intersection for green signal. It needs to reach its destination as fast as possible. Even though emergency vehicles have higher priority on the road, but still at the traffic signal there is lag to give enough priority to pass through the signal. Sometimes they need to wait for the signal to favor them in a congested traffic or they may have to take part in dangerous movement which may result in collision. The better way to reduce the waiting time of such vehicles is by making the traffic signal green for providing easy pass through. So that the safety of other vehicles are also taken care. In this paper, whenever the emergency vehicle is approaching preemption messages are provided to the traffic signal unit. So these signals interrupt the normal operation of the traffic light and make it green for the emergency vehicle. It is a type of Vehicle-to-Infrastructure (V2I) communication. The proposed system uses GPS method to get the location data and employs ZigBee for communicating efficiently with the intersection module. There is no requirement of Line-of-Sight employed in infrared based preemption methods. Also eliminate the false trigger occurring in sound (siren) based method due to noise and fading. Using this approach, it is possible to serve multiple emergency vehicles reaching the traffic intersection according to their distance from the intersection and accurately taking the decision to turn the signal green for the particular vehicle. There is no involvement of driver of the EV in anyway, it is fully autonomous and it can be used as a part of ITS. © 2016 IEEE.
