“…After that, a light-dependent resistor (LDR) will detect the brightness of the surroundings [40]. So, when the light level decreases, the LDR will send the signal to the controller unit to switch ON the light [24]. Next, a flow meter and a check valve are used in this system to measure the volume or mass of liquid and to allow fluid flow only in one direction, respectively.…”

“…Photosynthesis occurs as the plant converts light energy into chemical energy to produce glucose, which provides the plant with food and allows it to live, grow, and reproduce. In order to resolve this problem, a light-dependent resistor (LDR) is used to control the light intensity [24]. When the light level decreases, the LDR will send the signal to the controller unit to switch ON the light.…”

Plantation methods, including hydroponics, have been extensively used in agriculture. They also employed a time-based irrigation system for the plant. The goal of this project was to create a self-sustaining indoor plantation system that uses soil moisture sensor data to control the flow of water when the sensor detects that the soil is almost dry. Soil conditions are monitored, and crops are irrigated more efficiently with the help of this new technology. Water is conserved by just watering the plants when they absolutely need it, rather than watering them continually all the time as the traditional method would require. Light-dependent resistors are used to measure the brightness of the surroundings in this project. As a result, the grow light will be activated when the ambient light level drops. With the help of a soil moisture sensor and a light-dependent resistor (LDR), one can create a system that automatically waters and lights plants. Finally, the soil moisture sensor collects data for the sprinkler system and displays it on the LCD screen, and then the appropriate measures are taken. When the soil's humidity level is high, the water that flows will be stopped.

 Finding the small signal mathematical model of the Zeta dc/dc converter in symbolic form  PWM-switch model approach with peak currentmode controlled Zeta dc/dc converter  Comparison of the theoretical model with simulation and prototype circuit resultsIn this study, dynamic analysis of non-isolated Zeta converter has been presented with peak current-mode (PCM) control in continuous conduction mode utilizing the PWM-switch model. While small signal analysis of Zeta converter has been reported in the literature with constant frequency voltage-mode control, its small signal analysis with PCM control has not been reported. The transfer function from control input to output voltage was derived in symbolic form considering the esr of the output capacitor. Figure A. Dynamic model derivation and verification process of Zeta dc-dc converter Purpose: The essential aim is to achieve small signal model of non-isolated Zeta converter with PCM control. Theory and Methods:First, non-isolated Zeta converter topology is adapted to analyze with the PWM-switch model. Using linear circuit analysis, and dc and ac equivalents of PWM-switch model, its fifth order small signal model is achieved for PCM control structure. The analysis was verified by PSIM simulations and real measurements taken from an experimental prototype circuit built. Results:The results were in good agreement up to half the switching frequency of the converter. The comparisons in terms of absolute mean error show that the overall magnitude and phase difference between the Bode plots of analysis and simulations is 0.895(dB) and 4.613(°). On the other hand, the gap between measurements and analysis is calculated as 1.746(dB) for the magnitude and 18.872(°) for the phase values on average. Conclusion:While the analysis and PSIM simulation results are in very good agreement, the analysis and measured results agree reasonably well. For simplicity, dc resistances of other components in the Zeta converter except the esr of output capacitor have been omitted in the mathematical analysis. The analysis and measured results would even be closer if these resistances were considered in the analysis.
