GARDUINO

GARDUINO is an Arduino-based system to supervise the temperature, humidity, soil moisture and light status of our plant and automatically provide its necessary needs like light, water, and pure fresh air and even some sensors are used to control some actuators.

• The watering of plants is controlled with a soil moisture sensor which is used to turn on the water pump as and when required.
• The temperature/humidity sensor is responsible for the turning on and off of a 12V DC cooling fans and light.
• The Water motor, light and fan can be controlled remotely using Google assistant or the Garduino website.
• With the soil sensor, temperature and humidity value can be monitored live using the Garduino website.

To manage your garden easily... not being present, you can use this as a robot that checks whether it needs to be watered or not.

Automated Garden Care

"Garduino" is an all-in-one plant maintenance system.

• Soil Monitoring: Uses multiple Resistive or Capacitive Moisture Sensors connected to the Arduino's analog pins to check the hydration of different pots.
• Environmental Sensing: A DHT11 or DHT22 sensor monitors ambient temperature and humidity to predict evaporation rates.

Actuation & Connectivity

• Irrigation: Controlled by a Peristaltic Pump or a standard DC water pump via a Relay Module. The pump triggers only when moisture falls below a specific threshold.
• Cloud Dashboard: Syncs data to Blynk via an ESP8266/ESP32 or a Python script on a host PC. This allows the user to manually trigger watering or view historic plant growth data from anywhere in the world.

For external Data analysis run the python script named as datavisualise.py which would run a infinite script and upload sensor data to a txt file which can be further used in MATLAB, R.

HARDWARE

ARDUINO UNO: It is the micro controller board that is equipped with sets of digital and analog input/output pins and has a USB connection to load programs from personal computers.

SOIL-MOISTURE SENSOR: It measures the volumetric water content indirectly in the soil by using soil properties like electrical resistance etc.

TEMPERATURE-HUMIDITY SENSOR (DHT11): The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor.

LED LIGHT & 12V DC COOLING FAN: These are triggered together by the DHT11 temperature-humidity sensor when the surrounding temperature drop down below a plant-healthy level.

RELAY: It is an electrically operated switch which is used where it is necessary to control a circuit by a low-power signal or where several circuit must be controlled by one signal.

DC 12V WATER PUMP SUBMERSIBLE: This is triggered by the soil-moisture sensor as and when the soil gets dry and watering of the plants is needed.

SOFTWARE SPECIFICATIONS:

The project is developed using JSON, REST, PHP, JS, HTML, CSS, Arduino, MYSQL, cloud services and webhooks (IFTTT).

CONCLUSION

The system will reduce the human efforts in gardening and also make the gardening automated and tech friendly. It also makes the appropriate use of resources like water and electricity which will reduce the wastage of these resources and will also improve the health and life of plants.

NOTE

This project uses many different tools whose detailed explanation would be not possible, so if your are not able to figure out anything, feel free to ping me.
