Grow more rice.
Use far less water.

Nero Pulse is India's first smart AWD device for paddy farming. It monitors water levels in real time and tells you exactly when to irrigate — saving water, reducing your farm's carbon footprint, and removing all guesswork.

The Problem

Paddy farming wastes water — and nobody can measure how much.

Rice is India's most water-intensive crop. Traditional flooding wastes 30–40% more water than needed, raises costs, and releases methane. Manual AWD exists — but it's unreliable and unscalable.

High Manpower Cost

High Manpower Cost

Manual AWD requires field staff to check water levels frequently — increasing costs and limiting the area that can be managed.

No Data Visibility

No Data Visibility

No real-time data, no history, no centralized view — making it impossible to manage water across large programmes.

Inconsistent Adoption

Inconsistent Adoption

Without automated thresholds, AWD success depends on farmer discipline. Misreading leads to over-irrigation or crop stress.

No Digital Integration

No Digital Integration

Manual pipes can't send alerts, feed dashboards, or integrate with advisory systems — limiting programme-level monitoring.

The Solution

AWD: the proven technique that Nero Pulse makes practical.

Alternate Wetting and Drying lets paddy fields dry partially between irrigations. It doesn't stress the crop — it makes it stronger. Nero Pulse makes AWD measurable, automatic, and scalable.

Saves 30–40% Water

Irrigate only when water drops to the correct threshold — not continuously. No yield reduction.

Maintains or Improves Yield

Controlled drying promotes stronger roots and better soil aeration — leading to equal or better grain production.

Cuts Methane 30–70%

Flooded paddy is a top methane source. AWD dramatically reduces emissions — lowering the farm's carbon footprint and enabling carbon credit eligibility.

Lowers Input Costs

Fewer irrigations means less electricity, less diesel, better fertilizer efficiency — directly boosting farm profitability.

How It Works

Simple. Accurate. Automatic.

From installation to harvest — Nero Pulse takes the guesswork out of paddy irrigation.

Install in your paddy field

Install in your paddy field

Place Nero Pulse with 15 cm above and 15 cm below ground. The ultrasonic sensor starts measuring water level immediately with ±0.5 cm accuracy.

Data goes to your phone

Data goes to your phone

Via built-in e-SIM, water level readings flow to the Fyllo cloud — available on your mobile app, web dashboard, and APIs. No WiFi needed.

Get color-coded alerts

Get color-coded alerts

Green = water adequate, don't irrigate. Yellow = getting low, prepare. Red = irrigate now. No technical knowledge needed.

Track and prove savings

Track and prove savings

Dashboards show water savings, methane reduction, and irrigation events across farming clusters — for reporting and carbon credit documentation.

Device Features

Built tough. Built for paddy fields.

Designed to survive and perform in harsh, flooded conditions — season after season.

Ultrasonic Touchless Sensor

No contact with water — no fouling, no corrosion. Measures water level from above the waterline for long-term durability.

±0.5 cm Accuracy

Lab and field tested across 16 readings. Consistent precision critical for reliable AWD threshold management.

Debris & Environment Calibration

Automatically adjusts for debris accumulation and environmental factors — maintaining accuracy in real field conditions.

Solar + EV-Grade Battery

Continuous operation through the entire paddy season — transplanting to harvest — with no manual charging needed.

e-SIM Connectivity

Works in remote paddy regions without WiFi. Data flows from field to cloud via mobile network — wherever there's basic coverage.

API & Dashboard Access

Enterprise-ready. FPOs and government programmes can integrate Nero Pulse data into their own monitoring systems.

Nero Pulse vs Manual AWD

Why go digital with AWD?

Traditional AWD pipes require physical visits and produce no data. Nero Pulse automates the entire process.

Understanding Nero Pulse and AWD.

What is Fyllo Nero Pulse and what problem does it solve?

Fyllo Nero Pulse is a solar-powered IoT water level sensor for paddy fields that enables AWD — replacing manual monitoring with real-time, ±0.5 cm accurate data sent directly to a farmer's phone.

Traditional paddy farming floods fields continuously, wasting 30–40% more water than needed, increasing electricity and diesel costs, and producing methane emissions. AWD is the scientifically proven alternative, but manual field visits make it error-prone and hard to scale.

Nero Pulse digitizes AWD completely. The device measures water level around the clock and sends color-coded alerts — green (adequate), yellow (check soon), red (irrigate now). FPOs and government programmes get a dashboard to monitor all farms simultaneously.

30–70%
Methane emission reduction

from paddy fields using AWD — directly lowering the carbon footprint of rice cultivation and making Nero Pulse relevant for climate-smart agriculture and carbon credit programmes.

How does the ultrasonic touchless sensor work?

Nero Pulse uses an ultrasonic sensor that measures water level by emitting sound waves — without touching the water. Accuracy is ±0.5 cm, unaffected by water EC, pH, or salinity.

Traditional contact-based sensors corrode, foul with algae, and lose accuracy in paddy conditions. Nero Pulse measures from above the waterline with no physical contact, ensuring long-term durability.

The device is installed 15 cm above and 15 cm below ground level, covering the full range from flooding to pre-harvest drainage. Readings are transmitted via e-SIM to Fyllo's cloud in real time.

How is Nero Pulse different from a traditional AWD pipe?

A traditional AWD pipe requires physical visits, relies on human judgment, and produces no data. Nero Pulse automates measurement, sends real-time alerts, stores history on the cloud, and provides multi-farm dashboards with API access.

The manual AWD pipe is a simple observation tube. Farmers must walk to the field, visually estimate water level, and manually decide when to irrigate. There is no historical tracking, no centralized view, and no way to scale across large programmes.

Nero Pulse replaces all of this with automated, ±0.5 cm accurate readings, push alerts to phone, cloud data storage, dashboards for FPOs and government agencies, API integration for existing monitoring systems, and timestamped data for methane reduction verification.
