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.

“…Light-controlled photoresistors are a type of variable resistor. Photoconductivity is the ability of a photoresistor to lower its resistance as the intensity of the light it receives rises [33], [37], [41]. As well as lightsensitive detector circuits, photoresistors may be used in circuits that are triggered by either light or dark [42].…”

“…PV is often used to harvest solar energy to power other electronic devices, which is ideal for powering LED. Hence, a solar powered LED street lighting was developed, where PV panel energy supply and LED light intensity dynamic regulation are realized [10]. However, the impact of heat loss on energy conversion efficiency generated by PV panel has not been paid attention to.…”

The energy harvesting system achieved from one environmental energy channel is facing more and more challenges in meeting the power supply of electronic energy‐consuming devices. In this study, a combined photovoltaic (PV) and Thermoelectric Generator (TEG) energy management system is proposed with intelligent self‐powered technique for high‐power light‐emitting diodes (HP‐LED) lighting. Both the solar energy and waste heat induced by PV and HP‐LED are synchronously converted into electrical energy. Self‐powered by this gathered power, an adaptive light intensity control of HP‐LED is also realized using the established feedback path between ambient light and HP‐LED light. Experimental results show that the supply voltage of the TEG required for startup of the whole system can be decreased as 20.8 mV. Only 10 s is needed to complete the startup process under sufficient light, while 25 s in case of insufficient conditions. This energy management can provide a new technology for future smart home and greenhouse planting.

“…Solar photovoltaic panels make it possible to convert solar energy into electric energy for streetlights. During the day, energy from sunlight is captured by solar photovoltaic panels and converted into electrical energy stored in the battery, and the energy of the battery can be used to power streetlights at night [16][17][18][19][20][21][22]. The literature describes some LED driver circuits that are applied to a DCinput voltage source, such as a solar photovoltaic panel or a battery, suitable for powering LED street lighting applications [23][24][25][26][27][28][29].…”

With the global advocacy of green lighting and the urgent need for energy saving and carbon reduction, more and more street lighting applications have entered the era of being replaced by light-emitting diode (LED) lighting sources. This paper presents a new LED streetlight driving circuit applied to a direct current (DC)-input voltage source, which consists of a buck converter combined with a flyback converter to reduce the number of circuit components required and to recover the leakage energy of the transformer to improve energy conversion efficiency. In addition, this study also completed the analysis of the operational principle of the new LED streetlight driving circuit, and developed a prototype LED streetlight driver with DC-input voltage of 48V and output power of 72 W (36 V/2 A). Finally, the measurement results of the prototype circuit show that the output voltage ripple rate was less than 15%, the output current ripple rate was less than 6%, and the circuit efficiency was as high as 91%.
