Smart paddy water monitor
How we would build a low-cost IoT system that tells paddy farmers their water level by SMS — so they only visit the field when it matters.

The challenge
Rice farmers walk to their fields every morning and evening to check water levels. In the dry season, one missed check can mean a damaged crop.
Off-the-shelf sensors are expensive and usually need Wi-Fi, which rural fields don’t have.
Our solution
We would design an ESP32-based ultrasonic water-level sensor with a solar panel and battery, sealed in an IP65 enclosure. Readings travel over the mobile network, so no Wi-Fi is needed.
Farmers get an SMS when water drops below their chosen level, and can see the history in a simple mobile app.
