IoT Based Smart Irrigation

Sensor-driven irrigation control with a mobile monitoring app.

Case Study

Problem Statement

Manual and timer-based irrigation wastes water because it doesn't account for actual soil moisture, leading to over- or under-watering of crops.

Our Solution

A soil-moisture sensor connected to a microcontroller reads live moisture levels and automatically triggers a water pump relay when the soil is dry, while sending readings to a mobile app over Wi-Fi so the farmer can monitor remotely.

Features

  • Real-time soil moisture reading and threshold-based pump control
  • Wi-Fi telemetry using ESP8266/ESP32 to a cloud dashboard
  • Mobile app (Blynk/Flutter) showing live moisture graph
  • Manual override switch in the app
  • Low-moisture and pump-run notifications

How It's Built

  1. 1

    Sensor node reads analog moisture value every few seconds

  2. 2

    Microcontroller compares reading against a configurable threshold

  3. 3

    Relay activates the water pump when soil is below threshold

  4. 4

    Readings are pushed to a cloud dashboard for remote monitoring

FAQ

Do I need to buy hardware separately?

Yes, this kit is source code + documentation + guidance. We provide the exact component list and wiring diagram so you can source parts locally.

Can I simulate it without hardware first?

Yes, we include a Wokwi/Proteus simulation reference so you can test the logic before wiring anything.
