[0017] This invention is an Automatic Irrigation System for houseplants, utilizing sensors to indicate the conditions of each plant. It also provides accurate information about environmental conditions and the overall status of the device. This enables watering and fertilization optimization for each plant. This device includes various watering modes and a specialized fertilization system for each plant, preparing specific fertilizers for each plant. Furthermore, by simulating humidity, sound, light, and watering combined with nitrate fertilizer, it replicates the environmental conditions of rain accompanied by thunder and lightning.Technical Problem
[0018] Studies have shown that improper watering and fertilization account for 85% of houseplant deaths. Insufficient care and maintenance causes nearly 30% of houseplants to die within the first year of life. The overwatering or under watering of plants can result in root rot, wilting, and death, while improper fertilization can lead to nutrient deficiencies or even toxicity. Approximately 60% of houseplant deaths are caused by overwatering, while approximately 20% are caused by under watering. There might be differences in the nutritional requirements of different plants even within the same species. Nevertheless, many individuals use the same fertilizer for all their plants and pots, taking advantage of the fact that every plant, at each stage of its growth and under different weather and soil conditions, requires a specific amount of nutrients. The longevity of plant species is also reduced because they live in indoor environments where they follow human life rhythms, despite their adaptation to periodic natural events.Solution to Problem
[0019] To address the stated problems and improve plant maintenance conditions, especially for apartment plants as shown in Fig. 1 , 2, and 3, a specialized irrigation and fertilization system has been presented. This system is designed in a vertical form across different levels. On the lowest level 1 , electric valves 7, water outlets 8, moisture sensor ports 9, on / off switches 10, charging ports 11 , and growth lamp power supply ports 12, along with the device's battery, are located. On the first level 2, there is a water reservoir 13, water TDS sensor 14, water pump 15, water inlet 16, and float valve 17, alongside a water levelindicator 18 and two riser channels (for passage of wires and water hoses between levels (not shown)). The second level 3 houses the fertilization section, containing at least four liquid fertilizer cartridges 19, indicated by level indicators 20, along with electric drip valves 21 , a collector 22, and a flow meter 23. At the top level 4, there is an electronic board and display unit 24, environmental temperature, light, and humidity sensors, and a humidifier 25, with an embedded water pouring sink 6, a one-way valve 27, and a rotating head 5 on the device as shown in Fig. 4, which holds a humidifier nozzle 26, a flash lamp 28, and a camera 29. Additionally, an application has been considered as a user interface besides the display. There is no claim regarding the software aspect of the design. Furthermore, a moisture sensor is installed in each pot, with its cable connected to the back of the device. The necessary number of sensor ports 9 and water outlets 8 have been provided for the pots.
[0020] In the fertilization level 3, as shown in Fig. 3, there are at least four liquid fertilizer cartridges 19, with three cartridges holding separate N, P, and K element agents, and a separate cartridge for another specialized fertilizer like humic acid. It is possible to add more cartridges and specialized fertilizers. Based on the control command from the board, which considers a specific fertilizer with different percentages for each plant (pot), a certain amount of each fertilizer is injected for blending. The operation works as follows: a collector in this level has one main input for pure water, one main output for water mixed with liquid fertilizers, and four secondary inputs for injecting liquid fertilizer. Electric drip valves 21 and drip counting mechanisms 30 are used to control the injection amount. Before water pumping starts, the fertilizer drops from each cartridge into the collector. Then, with the flow of water, these fertilizers are rinsed from the collector and delivered to the desired pot.
[0021] The watering process for a pot is as follows: the electronic board, considering default and customized instructions for each plant, pot, or a row of plants in a garden or greenhouse, determines specific amounts of water and a specified ratio of fertilizer containing N, P, and K elements, along with other specialized fertilizers. Initially, it commands the designated output electric valve 7 to open, then prepares the customized fertilizer for each plant using the electric valves ofthe cartridges 21 and water pump 15, as explained above. This prepared solution is delivered to the respective pot via the corresponding port 8 and connecting hose. The volume of water sent to each plant is measured by the flow meter 23 (located after the collector 13) and controlled by turning off the pump 15 after supplying the required amount of water.
[0022] Furthermore, it's possible to connect multiple pots that have similar plant species to one output and define in the device to consider the water and fertilizer amounts proportionally for the connected pots. This method reduces the occupancy of ports and covers more pots.
[0023] As shown in Fig. 3, the water supply method for the device is through the water inlet 16, accompanied by the float valve 17, or through the sink 6. The water supply for the humidifier is organized such that on the top level 4, beside the (ultrasonic) humidifier device 25, a reservoir 31 is placed. Before reaching the fertilizer collector 22, the water pump 15 fills this reservoir by initially using a three-way passage 32 to fill the humidifier reservoir. This way, the humidifier reservoir 31 is always filled. Considering that the humidifier requires water with low TDS, if the water used for the plants has high TDS, the water charging path for the humidifier should be separate. Hence, a valve 33 is incorporated that diverts the water path from the pump 15 to the humidifier reservoir 31 , redirecting only the poured water from the sink 6 to the humidifier reservoir 31 , filling it. Moreover, a one-way valve 27 beneath the sink 6 is included to drain the water pumped from it.
[0024] The assessment of a plant's (or a row of plants') watering needs is determined through moisture sensors, considering the specific soil dryness or moisture levels required for each plant type. This information is pre-set in the software library and stored in the electronic board's memory for all pots. When the soil dryness reaches a predefined threshold, the irrigation process commences.
[0025] In other similar devices, to gauge a plant's requirement for fertilizer or nutrients, Nutrient sensors are employed, an electronic module measuring soil Electrical Conductivity (EC) levels. The optimal EC range in soil is typically between 110 to 570 milliSiemens per meter (mS / m). Lower EC levels indicate a lack of available nutrients, while higher levels suggest nutrient abundance.However, specialized nutrient sensors capable of analyzing separate elements, such as N, P, K, etc., measure all important elements individually. As this current device prepares specific fertilizers for plants, simple EC measurement sensors are not used. Instead, specialized nutrient sensors gather detailed information on each plant's elements, which is then imported into the device.
[0026] As shown in Fig. 4, the rotating head 5 of the device is a movable part with one rotational degree of freedom, accommodating the humidifier nozzle 26, flash lamp 28, and camera 29. These components are rotated collectively using a single motor, providing a 360-degree working range. The motor is programmable, allowing control over its speed, direction, and stop angle. After each full rotation, the direction is reversed to prevent tangling of water hoses and wires. The installed camera 29 monitors the visual appearance of plant leaves through image processing, reporting events to the user and advising on new irrigation and fertilization decisions in risky situations.
[0027] Another feature of this device is a simulated thunder and lightning function, which might be beneficial for plant species accustomed to periodic natural events. It can also enhance the user experience. Activation of this feature can be synchronized with external weather conditions or controlled at the user's discretion. The operators for this simulation include creating intermittent light flashes via the flash lamp 28, generating thunder and rain sounds from the speaker, irrigating with nitrate fertilizer to all pots individually and sequentially, producing humidity through the humidifier 25, and infusing rain scent fragrances from its cartridge 34 into the humidifier reservoir 31 .Advantageous Effects of Invention
[0028] With its innovative features and capabilities over previous inventions in the field of smart irrigation device for houseplants, it represents an innovative step and a significant advantage. Among its features is NPK fertilization, which allows each plant to receive a customized ratio of N, P, and K elements. By doing this, it is ensured that not all plants receive the same fertilizer. Furthermore, plants require different nutrition throughout their lifecycle and during different seasons. Due to this, conventional EC sensors are not used, but rather specialized sensors for nutrient elements that can analyze elements separately.
[0029] The addition of a rain simulator accompanied by thunder and lightning offers several benefits; it effectively stimulates photosynthesis and creates a dynamic environment that mimics natural conditions. In particular, plant species accustomed to periodic natural events will benefit from it. Apart from its physiological benefits, it also provides audio-visual pleasure to users.
[0030] Furthermore, it is possible to mention aspects such as comprehensive monitoring of environmental conditions, monitoring of the device and plants' health through various sensors, utilizing sensor data and its analysis, and providing new irrigation and fertilization programs. The use of cameras, image processing, and a misting nozzle, all on a rotating head, and the utilization of a motor for movement are among the other advantages of the device.Brief Description of DrawingsFig. 1

[0037] The components, fluid pathways, and their interconnections are shown in [Figure 3].
[0038] An enclosed view of the nozzle and the components on it is shown in [Figure 4]-Examples
[0039] The first step is to connect the device's water source and power source. Then, we attach the hose and moisture sensor to each pot and connect their other ends to the ports at the back of the device. We charge the cartridge of N, P, and K fertilizers, as well as the specialized fertilizers. Through the device's application, we input the plant species of each pot and other information such as age and height. The program itself contains care information for various plant species and, if a plant species isn’t available or the user requires custom settings, they can be applied. After measuring soil moisture, the device begins irrigation. Additionally, using specialized nutrient sensors, we obtain the nutritional status of the soil in each pot and input it into the device. Based on this information, the device prepares specific fertilizer for each plant and administers it along with irrigation. For the device to have updated information, periodic nutrient measurements must be made using specialized sensors, and the application plots plant status graphs. Moreover, the application provides notifications and alerts, such as the recommended time for soil replacement. By adjusting the environmental humidity level in the device settings, the humidifier works within that humidity range. Another feature of the device was the rain simulator accompanied by thunder and lightning, which can be activated automatically, synchronized with weather conditions in a given geographic location, or manually. It is, however, announced to the user beforehand and initiated with their permission due to the high sound and light levels. The camera mounted on the rotating head monitors the plant leaves through image processing, reports events to the user, and advises them in making informed decisions about plant irrigation and fertilization when at risk.Industrial Applicability
[0040] It is applicable to houseplants used in residential, office, commercial, educational, therapeutic, lodgings, greenhouse plants, and generally within the domain of agricultural automation.
