The greenhouse, a crucial component of agricultural infrastructure, has been instrumental in the advancement of modern agriculture by providing plants with a healthy environment. Manually monitoring and managing the many settings is challenging. Maintaining production quality is another important responsibility. This study proposes an automated greenhouse monitoring and control system that uses a variety of sensors, including temperature, soil moisture, light, photoionization, and soil moisture sensors, to collect potential environmental parameters of the greenhouse and integrate Arduino Uno R3 (to store and process data). The goal is to create a system that would concentrate exclusively on the cultivation of papaya, cucumber, tomato, and brinjal. The outcomes will be a fully comprehensive
 Since the dawn of civilization, farming has been one of man's main vocations, and even now, manual labour is still necessary in many situations. To grow the correct crops at the right time in the right soil, traditional farmers must routinely visit their fields to measure the many environmental factors, including temperature, humidity, light intensity, and soil moisture. Even though this conventional farming method has been around for a while, it is chaotic and frequently results in low productivity rates since the farmer is unable to correctly assess all the variables.  There are several issues relating to people's food supplies brought on by climate change. The country's horticulture and agriculture industries depend heavily on greenhouses because they
A structure where plants are grown is called a greenhouse. The cultivation of fruits, vegetables, and flowers is frequently done in greenhouses. Sunlight, soil moisture content, temperature, and other fundamental elements all have an impact on plant growth. Inside a greenhouse, it is challenging to manually manipulate these physical parameters. Automating this monitoring system is one option. An intelligent microcontroller-based greenhouse system is another method of controlling these parameters. As it is expensive and some physical elements are interconnected, it is impossible to automatically control every aspect that influences plant growth. With a redesigned architecture, IOT is now used for this monitoring. IOT-based greenhouse monitoring models have also been used recently. A green revolution in agriculture may result from the implementation of "AUTOMATED GREENHOUSE MONITORING SYSTEM". The introduction of this method will contribute to an increase in controlled-environment farming. An essential component of the horticulture and agriculture industries is the greenhouse environment, which is utilized to grow plants under regulated climatic conditions for effective production. The use of WSN for greenhouse monitoring as indicated in  and  may also be taken into consideration. The factors of soil moisture, temperature, and light are necessary for plant growth. These parameters must be produced by the greenhouse's environment.  The majority of typical greenhouse plants need a temperature range of between 18 to 24 C. (64 F-75 F). We find these temperatures in most greenhouses across the world since they are thought to be ideal for the majority of common crops. Growers rarely deviate from this temperature range because doing so would typically result in delayed or stopped growth and subpar produce quality. In greenhouses and other indoor growing environments, humidity control is essential. Any facility will experience condensation if the humidity is not controlled. The growth of diseases that can quickly wipe out vast quantities of vegetables, cannabis, or any other crop is caused by the availability of this free water.
Through our initiative, we are putting forth a system that will concentrate on creating a greenhouse climate for a certain type of plant.
To gauge and keep an eye on the many greenhouse factors, such as temperature, soil moisture, light, and dangerous gasses, and to make adjustments as necessary to meet the needs of the crop in order to maximize and accelerate growth Yield.

In 2019, the International Conference on Computing, Control, Networking, Electronics, and Embedded Systems Engineering presented a paper titled "Greenhouse Monitoring and Control System Based on Wireless Sensor Network. “In a greenhouse, wireless sensor nodes equipped with temperature and humidity sensors were used to create a WSN. Analysis and Prediction of Crop Greenhouse Parameters Journal of Computer Applications International, IEEE.The parameters of the crops' greenhouses are examined using a variety of sensors. Cucumber, tomatoes, brinjals, papaya, and other crops were chosen for analysis. The necessary ideal range of greenhouse characteristics for each of these crops is also taken into account simultaneously.
IV. COMPONENTS USED
V. PROPOSED METHODOLOGY
By employing a photoionization sensor to measure the amount of poisonous gasses like ethylene, carbon dioxide, and methane, among others, we will be able to address the problem of crop damage caused by these gasses.
Since temperature is the most important factor to consider while monitoring a greenhouse, this project will help us control the temperature. The technology turns on the fan automatically when the temperature exceeds a preset or critical threshold. On the other hand, the fan automatically shuts off if the detected temperature falls within the usual range or below the set level.
Crop yield is influenced by humidity levels, which can be measured and tracked in the system. For healthy plant growth, soil moisture is crucial. Using a soil moisture sensor, it has been determined
The amount of light present is crucial in a greenhouse setup. Crop growth requires the right amount of light intensity. Variations in light intensity may negatively impact plant development and reduce output. To fix the low light intensity issue within the greenhouse, artificial lights are utilized.
Artificial lights automatically come on when a defined level of light intensity is compared to a lower level. The artificial lights automatically turn off when the ambient light intensity is within a typical range.
We can assess the level of harmful chemicals like benzene, carbon dioxide, methane, and ethylene in the air to prevent damage to crops. We will address the issue of agricultural damage brought on by harmful gasses with our project.
The circuit includes the following parts: an LDR, an LM35, a soil moisture sensor, three DC motors, an Arduino Uno, two yellow LEDs, one red LED, and three motors. We use an LM35 for temperature functionality, with one end grounded and the other linked to the Arduino UNO's A4 pin. Its output is derived from the Arduino UNO's pins 5 and 7. These pins are later connected to a transistor array motor and an LED heater.
An LDR with one end linked to the ground and the other to the Arduino UNO's A0 pin is used to control the light. Its output is obtained from Arduino UNO pin number 13, which is connected to the yellow LED.
We have a potentiometer that serves as a soil moisture sensor for functionality related to soil moisture level. One end of it is attached to the ground, and the other end is connected to Arduino UNO pin number A5. A DC voltmeter is wired to it. Its output is obtained from pin number 6, which is connected to a motor via pin number 15 of the transistor array
As we can see, the messages related to the current situation are printed on the virtual terminal. The fans are activated because the temperature is over the ideal level for the situation. The LED is turned on because the greenhouse doesn't have enough light intensity. The water in the pump is turned on because the water level is low.
VII. FUTURE SCOPE
By using WSN, the system may be turned wireless.To find too many pesticides, another sensor is employed, like enzyme biosensors. The automatic greenhouse monitoring system's equipment is powered by unconventional energy sources like solar cells and wind turbines. It will start a revolution and has a promising future in the sector of agriculture.
In this study, a streamlined, clever monitoring and controlling system for greenhouse farming is described. The greenhouse\'s gas level as well as changes in temperature, humidity, and light intensity could all be tracked by the greenhouse\'s monitoring and control system. Based on the many changes in the environment, the various sensors were able to adjust. This study aims to support small-scale farmers\' convenience and ease of plant growth. Small farmers will be able to grow healthy crops all year long with little oversight according to the suggested method.
