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
Technology Stack
How It's Built
- 1
Sensor node reads analog moisture value every few seconds
- 2
Microcontroller compares reading against a configurable threshold
- 3
Relay activates the water pump when soil is below threshold
- 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.
