# 🌱 Smart Plant Monitoring System using ESP8266 & Blynk
This project is an IoT-based **Smart Plant Monitoring System** built using the ESP8266 NodeMCU, Blynk IoT platform, and sensors for monitoring temperature, humidity, soil moisture, and motion detection.
> 💡 Ideal for home gardening automation or learning how to integrate hardware with IoT platforms like Blynk.
---
## 🔧 Features
- 🌡️ **DHT11 Sensor** – Measures Temperature and Humidity
- 💧 **Soil Moisture Sensor** – Monitors soil wetness and displays it.
- 🚨 **PIR Motion Sensor** – Detects movement and triggers Blynk alerts
- ⚙️ **Relay Module + Water Pump** – Allows plant watering via Blynk app
- 📱 **Blynk IoT App** – View real-time data and control the pump remotely

## 🧰 Hardware Used
| Component | Quantity |
|----------------------|----------|
| ESP8266 NodeMCU | 1 |
| DHT11 Sensor | 1 |
| Soil Moisture Sensor | 1 |
| PIR Motion Sensor | 1 |
| Relay Module | 1 |
| Mini Water Pump | 1 |
| 3.7V Li-ion Battery | 1 |
| Jumper Wires | Several |
| Breadboard | 1 |

## 🖥️ Software Used
- **Arduino IDE** (for writing and uploading code)
- **Blynk IoT App** (for dashboard and device control)
- **Libraries:**
- `ESP8266WiFi.h`
- `BlynkSimpleEsp8266.h`
- `DHT.h`
---
## 🧠 How It Works
- Sensor readings are sent to Blynk every few seconds.
- If motion is detected, an alert is sent to Blynk and logged as an event.
- The water pump can be manually activated via the Blynk app using the button assigned to Virtual Pin `V12`.
