"Chonnatee" –
Real-time water level, water & air quality monitoring and solar pump control

Chonnatee is a modern IoT platform for water resource management. It monitors river, canal, weir, drainage pipe and groundwater levels, together with salinity, pH, DO, rainfall and PM2.5 — all sent to the cloud in real time with automatic dashboards and alerts.

  • Real-time monitoring of water level and water–air quality
  • Configurable alerts for flood, drought and critical air quality
  • Web and mobile control for solar-powered water pumps
  • Designed for local governments, irrigation agencies and smart city programs

From local communities to provincial operations — unifying fragmented water data into one coherent picture.

Chonnatee – Water level & water quality monitoring system

Chonnatee Solution Overview

Chonnatee is an all-in-one solution that integrates field sensors, wireless communication modules, solar power and a cloud platform. It is ideal for projects that require water level and water–air quality monitoring across main river basins, urban communities and underground water bank projects.

All measurement points send data to the cloud via 4G, visualized on a real-time dashboard. Historical data can be exported and analyzed with AI to support planning for water management, risk analysis and preventive maintenance.

Chonnatee supports a wide range of additional sensors, such as flash-flood detectors, wastewater quality sensors, soil-moisture probes, temperature and humidity modules, and other agriculture or industry-specific devices. All sensors can be added by simply plugging them into the gateway, and the platform will automatically stream the data to the cloud. The dashboard can also be customized to fit the unique operational needs of each area or agency.

Key Benefits for Your Organization

Early warning for flood and drought

Monitor water levels in real time with color-coded thresholds (Green – normal, Orange – alert, Red – critical). Help local authorities decide when to warn citizens and prepare mitigation plans in advance.

Data-driven water resource management

Accurate data on water level, water quality and rainfall supports decision-making for irrigation releases, storage planning and underground water bank operations in a more sustainable way.

Reduce manual workload & increase safety

Schedule automatic on/off operations for pumps and reduce the need for staff to travel to remote or high-risk sites to manually switch pump systems, especially during heavy rain or flash floods.

Predictive maintenance planning

Record pump operation history and sensor status for every site in the cloud. Use the data to plan preventive maintenance, reduce downtime and extend equipment lifetime.

Foundation for Smart City & climate resilience

Combining PM2.5 and rainfall data with water level information allows municipalities and provinces to build environmental dashboards to monitor local climate risks and support long-term adaptation strategies.

Key Advantages of “Chonnatee”

A low-power cable-type water-level sensor designed specifically for canals, drainage networks, culverts, and flood-risk zones across Thailand. Chonnatee outperforms camera-based or ultrasonic solutions in power efficiency, accuracy, installation feasibility, and long-term field durability.

Chonnatee Key Highlights

Superior to Competing Technologies

  • Extremely Low Power Consumption – Operates on only 10–20W Solar Cell, ideal for remote areas without grid power.
  • High Accuracy, Not Affected by Light – Measures water level directly as numeric values. No image processing, no issues with glare, shadow, fog, or heavy rain.
  • Scalable Along the Canal – Cable sensors can extend hundreds of meters and support multiple sensing points in one line, enabling full visibility across the entire waterway.
  • Easy Field Installation – Mounts under bridges, in manholes, culverts, or drainage pipes without heavy civil construction or road closures.
  • Durable and Privacy-Safe – Built for harsh Thai environments: flood, sediment, heat, debris. No camera involved, ensuring zero privacy concerns.

Comparison with Other Technologies

Why “Chonnatee” is more suitable for Thailand’s field conditions compared to CCTV or Ultrasonic sensors — especially in power usage, accuracy, installability, maintenance, and long-term TCO.

Criteria Chonnatee
(Cable Sensor)
CCTV Camera Ultrasonic Sensor
Power Consumption Very low, operates with 10–20W Solar Cell High, requires continuous grid power Medium to high depending on model
Accuracy Direct numeric measurement; unaffected by lighting Sensitive to glare, fog, rain, low light, and reflections Can be disturbed by foam, debris, turbulence
Installation Feasibility Compact sensor head; easy to mount under bridges or culverts Requires pole, good angle, and weatherproof enclosure Requires elevation clearance and splash protection
Environmental Durability Designed for flood, sediment, heat, and debris Lens fogging/dirt; requires frequent cleaning Sensor degradation due to sediment or impact
Privacy / PDPA No personal data; measures water level only Captures people, vehicles — high PDPA risk No personal imagery, but still requires access control
Long-Term TCO Low energy and maintenance cost; ideal for hundreds of sites High electricity + lens maintenance across multiple locations Periodic sensor replacement required

Note: Green = strong advantage, Yellow = partial limitation, Red = disadvantage vs. “Chonnatee”.

Example Use Cases & Pilot Projects

1. Reservoirs & main river channels

Deploy water level and water quality sensors along major reservoirs, rivers and canals to monitor flood and drought conditions. Combine with satellite imagery and national radar rainfall data.

  • Buoy or fixed-level sensors for open water bodies
  • Alerts via dashboard and LINE / mobile notifications
2. Urban drainage & underground water banks

Install sensors in drainage pipes and underground water bank points in cities to monitor waterlogging, drainage performance and infiltration activities.

  • View pipe and underground water bank status in real time
  • Analyze recurring flood spots and plan structural improvements based on historical evidence
3. Groundwater wells & agriculture

Monitor groundwater levels and water quality for community water systems or modern agricultural projects to ensure sustainable water extraction and usage.

  • Automatic control of solar pumps by schedule or water level
  • Alerts when water drops below safe thresholds
4. Smart PM2.5 & environmental projects

Deploy PM2.5 sensors together with rainfall and water level monitoring to analyze the relationship between air quality, precipitation and water conditions in specific areas.

  • Build environmental dashboards at subdistrict / municipality level
  • Communicate data to citizens in a simple and transparent way
Real-world installations include reservoirs in Nan province, underground water bank areas in Bangkok, groundwater and technology transfer centers in Ubon Ratchathani, as well as municipal pilot sites in Nonthaburi and other provinces.

Project Models & Estimated Budget

The Chonnatee solution can be deployed as a **per-station package**, including field sensors, communication modules, solar power, cloud platform, and unified dashboards — all in one bundle. The cost per site depends on the selected sensor set, installation complexity, and the total number of stations in the project.
