 1 | # Plant Monitoring System Using IoT
 2 | ## Overview
 3 | - The aim of this project is to automate agriculture using IoT.
 4 | - In this project we used different type of sensors for collecting data from Agriculture.
 5 | - I Used Blynk Cloud for accessing sensors from anywhere from world.
 6 | - We can autom automate Water pump.
 7 | 
 8 | ## How It Works
 9 | - I Used Soil Moisture Sensor, DHT11 Sensor(Tempereture And Humidity) for collecting Data.
10 | - After collecting data from sensor it will send to Blynk Cloud
11 | - Blynk can control Hardware devices from remotely, it can display sensor data, it can store data, vizualize it and do many other cool things.
12 | 
13 | - Soil Moisture Sensor collects moiture presents in soil i.e how much quantity of water present in the water.
14 | - DHT11 Sensor is collecting Tempereture and Humidity present in the air surround the agriculture.
15 | - Blynk Cloud will show all collected data in the form of Graphs and Charts so we can easily monitor our plants from anywhere.
16 | ### Working Of Blynk

20 | ## Hardware and Softwares We Need 
21 | 1) NodeMCU ESP8266
22 | 2) Soil Moisture Sensor
23 | 3) DHT11 Sensor
24 | 4) 5v Relay Module
25 | 5) BreadBoard
26 | 6) Jumper Wires
27 | 7) Water Pump 12v
28 | 8) 12v Battery
29 | 9) Blynk Cloud Account
30 | 10) Arduino IDE
31 |

35 | 
36 | ## How To Configure System
37 | 1. Connect The Hardwares According To Circuit Diagram.
38 | 2. Download Code From This Repository.
39 | 3. Download Required Libraries Into Arduino IDE
40 | 4. Connect NodeMCU to PC & Upload The Code into it.
41 | 5. Open Blynk Web App Or Mobile App and Create New Device.
42 | 6. Create Template and Add DataStreams:
43 | Pin V2,V5,V5 & D0 for Soil Moisture,Humidity,Tempereture and Motor Pump Respectively.
44 | 7. Create Web/Mobile Dashboard Using DataStreams Like Charts, Graphs,etc.
