    Ubiquitous greenhouse monitoring system
    (Institute of Electrical and Electronics Engineers Inc., 2016) Rao, K.; Srijana, K.; Prasad, D.; Chandrasekaran, K.
    A greenhouse is a structure generally made of glass, designed to provide protection and controlled environment to raise plants indoors. In order to achieve high quality and quantity of produce, proper management and data collection of the greenhouse environment is required. Manual practice of plant monitoring is laborious and time consuming. The proposed greenhouse system is an application which demonstrates the concept of Internet of Things and involves ubiquitous monitoring and controlling of environmental parameters within the greenhouse, which directly or indirectly control the plant growth and so their production. The system thus designed, mainly aims to remotely monitor and control the greenhouse using temperature sensor, light sensor, soil moisture, water level sensor and actuators through a customized webpage. Moreover, real-time representation of the sensed data is graphically plotted as well as stored for improved monitoring and further analysis, illustrating the concept of cloud instrumentation. © 2015 IEEE.

    IoT based Smart Management of Poultry Farm and Electricity Generation
    (Institute of Electrical and Electronics Engineers Inc., 2018) Sitaram, K.A.; Ankush, K.R.; Anant, K.N.; Raghunath, B.R.
    Poultry is one of the most important growing economic segments of agricultural sector in India today. Nowadays because of standardized farming management and good manufacturing practices, chicken production in the world has been increasing gradually. In contemporary world automation plays a vital role and concept of Internet of Things (IOT) is also emerging very fast, there is an approach to convert traditional systems into automated systems. The paper focuses on automation of poultry farm using IoT technology to perform various management related things. The environmental factors which affect the health of chicken such as temperature, humidity, light and Ammonia gas are monitored and the manual jobs like food feeding, water supply system, cleanliness are managed. If all these parameters are maintained, the production and quality of chicken increases. Along with this, electricity is generated from the methane gas which is produced from the chicken manure and stored in battery. The management and monitoring of the farm can also be done through a web based system. Which keeps track of the management of poultry farm from anywhere and at any time. © 2018 IEEE.

    Design and Development of an IoT-Based Gas Monitoring System for Underground Coal Mines
    (Springer Science and Business Media Deutschland GmbH, 2023) Tripathi, A.K.; Mangalpady, M.; Rao, N.R.N.V.; Ray, S.
    Safety in underground coal mines is a major challenge whenever the mine comprises of toxic gases. The risk of the presence of gas influences the overall productivity of the mines, which is a subject of concern to the mining industry. Therefore, there is a need for real-time monitoring of underground mine environment, so that the miners can be safeguarded in case of presence of toxic gases. In this paper, an attempt was made to evolve and validate an Internet of Things (IoT)-based gas monitoring system for monitoring underground coal mines environment, which includes multiple sensors for real-time measurement of different gases. The developed IoT-based gas monitoring system was tested and validated in the laboratory, under the controlled environmental conditions, for the measurement of carbon dioxide (CO2), carbon monoxide (CO) and methane (CH4) gases. Further, the test results were compared with the readings obtained by the digital multi-gas detector, which confirmed that the developed real-time gas monitoring system yields a good result. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    Enhanced pH Sensitivity of ISFET via TiO2 Gate Doping: A Novel Approach
    (Institute of Electrical and Electronics Engineers Inc., 2025) Herur, S.M.; Sharath Balaji, T.; Singh, M.
    This paper presents the simulation and analysis of an Ion-Sensitive Field-Effect Transistor (ISFET)-based pH sensor designed for accurate detection of ion concentrations through variations in gate voltage. The ISFET structure replaces the conventional gate of a MOSFET with an electrolyte and titanium dioxide (TiO2) doping, enabling the sensing of pH levels via ion-gate dielectric interactions. In this study, potassium chloride (KCl) is used as the electrolyte, and its influence on the ISFET's electrical behavior is systematically analyzed. The output characteristics, including the drain current (Id) versus drain-source voltage (Vds) under varying gate-source voltages (Vgs), are obtained using COMSOL simulation. The semiconductor and electrolyte models are meticulously coupled to ensure a realistic representation, capturing the ion-sensitive interface's behavior. A simplified global equation technique is employed to derive critical operating parameters efficiently, without explicitly modeling the feedback circuitry. The ISFET's performance is further evaluated by analyzing its sensitivity to pH variations and extracting relevant electrical characteristics for optimization. This work provides a comprehensive approach to simulating ISFET-based pH sensors, highlighting its potential for efficient and precise pH measurement in biochemical and industrial applications. © 2025 IEEE.
