We are living in a technology-based society where we have lots of innovative ideas day by day. These new innovations in IoT communications-based projects strive constantly to share and gather insight on the latest trends in the industrial IoT landscape. Here we focus on the IoT-based Smart Garden kit along with a Weather Station that can perform and even monitor a host of Gardening tasks.
Plants require water on a regular basis for proper growth. Water resources such as rivers, canals, ponds, lakes, wells, and many more have become contaminated nowadays due to human activities. Water became a scarce resource due to growing population, climate changes and rapid urbanization.
This IoT-based “Smart Watering System for Gardens Using Wireless Sensors Networks” is all about utilizing the sensors in the field of irrigation. These devices are equipped with water pump, sensors and can be controlled and monitored using the smartphone. This proposed system is used to implement a smart garden kit, which is used to provide the information about the plants and observe the daily monitoring of the plants. The recorded data can be used in the future. It also forecasts future rain.
This project is very much useful for the gardener and it will provide the important resources that can be useful for the growth of plants, generally this device is equipped with many sensors and has an automatic function. Smart garden project is watering system for gardeners which uses multiple sensors. Weather-Station is used to determine the ‘temperature’ and ‘humidity’ of air; it also helps in determining the predicted rain with the help of humidity and temperature sensors. The weather station helps in monitoring current weather as well as future weather. Perfect weather information helps in minimizing the use of water by turning off the water pump automatically.
This System utilizes ATmega328 micro controllers. This project is built to determine the level of moisture in the soil. The level of moisture in the soil should moderate. If the level of moisture is less then we have to provide water. If the level of moisture is more than there is no need to provide the water to the plants. So microcontrollers are programmed in such a way that it can provide watering plants twice per day. It also reminds me if there is no sufficient water in the tank.
This system mainly comprises of four main sensors, which are Barometric Pressure, DHT11 Temperature, and Humidity Sensor, Soil Moisture Sensor and Light intensity module sensor. The Soil and Light Intensity sensor used to measure the value by percentages. Besides, two actuators, which are the water pump and LED light can be used remotely or by using a button on the devices. The LED is purposely to replicate the sunlight and make the plant grow faster.
This IoT-based Smart Garden with Weather Station System can record the data and send the result to the user through the smartphone application named as Blynk apps. The concern of the project is to provide information about plants to end users. Present IOT device is also executed with the weather station sensors where it can observe all the readings of the sensor. The moisturizing property of soil, air humidity, and temperature and water pumps is all controlled by a weather station sensor. This project is advantageous for the users who are concerned about the growth of plants.

And an Atmega328 microcontroller is used to connect with external electronics circuits.
- ESP8266 WiFi MODULE:
ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board designed based on an integrated chip specifically to fulfill the needs of a new connected world. It can handle all the necessary overhead for communicating with your network, such as TCP/IP stack and communicating with your 802.11 networks. The ESP8266 WiFi Module is a self-contained SoC with an integrated TCP/IP protocol stack that can give access to your WiFi network (or the device can act as an access point). One useful feature of Uno WiFi is support for OTA (over-the-air) programming, either for the transfer of Arduino sketches or WiFi firmware
- TEMPERATURE & HUMIDITY SENSOR:
DHT11 is a low-powered electronic device that lets us get the value of the temperature and the moisture and it uses 1 wire protocol. The sensor consists of a capacitive humidity sensor and a Thermistor connected to a high-performance 8-bit microcontroller. It measures the surrounding air and outputs a digital signal on the data pin (no analog input pins needed).DHT11 is strictly factory calibrated that is extremely accurate on humidity calibration, hence easy to interface with other microcontrollers. Using dedicated digital module acquisition technology and temperature, humidity sensors ensure the products with high reliability and excellent long-term stability.
- SOIL MOISTURE SENSOR:
Plants require water on a regular basis for proper growth. This soil moisture sensor used to measure moisture or water level content in it. When the moisture level is high, the module gives a digital output of 5V and provides 0V when the moisture level is low in the soil.
A Liquid Crystal Display commonly abbreviated as LCD is basically a display unit built using Liquid Crystal technology. When we build real-life/real-world electronics-based projects, we need a medium/device to display output values and messages.
The internet of things (IOT) uses this platform to create apps. This is utilized to control the components like Arduino \Uno, Raspberry Pi, and others. It has its own graphical interface. It’s friendly, easy to use. This application uses the concept of dropping and dragging of widgets.

Measuring soil moisture plays a crucial role in gardening to support gardeners to manage their plants more efficiently. This technique also allows increasing yields and the quality of the plant by better management of soil moisture during critical plant growth stages. An Embedded system for automatic irrigation offers a potential solution to support site-specific irrigation management that allows producers to maximize their productivity while saving water. Moreover, this project technique enables the system to avoid over-irrigation, under irrigation, topsoil erosion, and reduce the wastage of water. Meanwhile, the system performance can be changed according to the situation of crops, weather conditions, soil, etc
