Plant monitoring is seen as one of the most important tasks in any farming or agriculture-based environment. This project automates plant monitoring and smart gardening using IoT in the NodeMCU system platform. The main purpose of this project is to provide comfort to the farmer by reducing the manual work by improving the overall performance of the system without the user’s direct interaction. The important parameters for the quality and productivity of plant growth are soil and air temperature, humidity and soil moisture. The plant health and growth information have to be provided to the user continuously by monitoring and recording these garden parameters. All the sensors used in this project are interfaced with the NodeMCU. And this information about the plant can be directly monitored and controlled by the farmer through their smart phone using IoT. The software’s used are Arduino IDE & Blynk IoT platform. Ardunio IDE is used for compiling and uploading the program to NodeMCU and Blynk IoT platform is used for monitoring the temperature, humidity, soil moisture, Water pump, and motion using sensors and update them into the blynk mobile Application through IOT and also displays the same values on LCD. Here we are using DC motor instead of water pump. Here relay works as a switch to ON/OFF the water pump. By using blynk mobile application user will control the water pump and enable the motion sensor to detect the animals. NODEMCU will gives the feedback to the user about water pump status and motion detection on the blynk APP.    

The major features of this project are:  

• Wireless monitoring and controlling using IOT technology.
• Blynk up will tell us the feedback of plant monitoring system about sensors data and water pump on/off status and motion detection status.
• User can enable the motion sensor from blynk app when he required.
• User can turn ON/OFF the water pump through Button and Blynk APP.
• Continuous monitoring of temperature and humidity using DHT11 sensor.
• PIR based motion detection.
• Continuous monitoring of moisture using Soil moisture sensor.
• Live monitoring using LCD display.

    The major building blocks of this project are:  

• Power Supply.
• NodeMCU.
• Dht11(temperature, Humidity Sensor)
• Soil moisture sensor.
• PIR sensor.
• Button.
• Water Pump along with Relay.
• LCD display.

    Software’s used:

1. Arduino IDE Compiler to write the program.
2. Embedded C language.
3. Blynk APP.
4. Express SCH for Circuit design.
