The Hardware

The Jalio Water Pod

The Jalio pod is built on a buoyant orange PVC pipe frame — rugged, lightweight and entirely self-contained. A waterproof electronics enclosure houses the ESP32 microcontroller, sensor boards, and 4G module, while a solar panel on top keeps the battery charged indefinitely in field conditions.

The design is field-proven — successfully deployed in an open water body during live monsoon conditions, with readings streaming to the cloud dashboard in real-time.

Jalio Technologies is founded by Pranav Bhat and incubated at the Krishik – Agri Business Incubator, UAS Dharwad. The company targets inefficient, manual water quality monitoring in fish, prawn and paddy cultivation — replacing guesswork with real-time IoT intelligence.

Field Deployment

Tested. In Real Water.

The Jalio pod was deployed in an ancient stone reservoir during active monsoon rainfall — proving waterproof integrity, solar performance in overcast conditions, and real-time 4G data transmission.

Applications

Where Jalio Deploys

02
Pollution Detection
TDS and turbidity spikes instantly flag industrial effluent discharge events. pH drops confirm acid contamination in real time.
Environmental Compliance
03
Irrigation Intelligence
Agricultural intake points monitored for dissolved solids and pH — preventing mineral buildup in channels and protecting crop yield.
Precision Agriculture
04
Aquaculture Monitoring
Fish farms depend on tight pH and DO windows. Jalio pods maintain 24/7 watch, alerting before stress conditions affect stock.
Fisheries
05
Drinking Water Safety
Municipal intake stations monitored for contamination. Automated threshold alerts integrate with water treatment SCADA systems.
Public Health
06
Research & Hydrology
Distributed pod networks give researchers spatial water quality datasets across entire river basins for climate and ecosystem studies.
