Compact 326 × 300 × 200 mm, 5 kg ASA buoy for practical deployment and maintenance

PB-030-AY Mini Water Quality Monitoring Buoy
A lightweight buoy platform for aquaculture ponds, campus landscape water and compact fixed monitoring points. It is configured as an integrated sensor, power, reporting and cloud-monitoring package—not sold as a fixed-parameter instrument.
Integrated buoy, sensor, power and remote-monitoring architecture
Up to four simultaneous sensors; standard pH and dissolved oxygen carrier with expansion for conductivity, ammonia and turbidity
20 Ah battery plus solar; ≥30 days in cloudy/rainy conditions for pH + DO at five-minute reporting
GPS, remote configuration, normal/warning/alarm modes and automatic restart after prolonged communication loss
300,000 offline records for four parameters—more than one year at five-minute sampling
Quick-plug sensors with support for an automatic dissolved-oxygen air-calibration action

Recommended integrated monitoring projects
Aquaculture
Continuously monitor pH, dissolved oxygen and selected water parameters in ponds and recirculating systems.
Campus and landscape water
Create a low-maintenance fixed point in small lakes, landscape water and enclosed water bodies.
Project pilots
Quickly validate the sensor package, reporting interval and cloud alarm logic before wider rollout.
Mobile or temporary monitoring
Use for seasonal, emergency or short-duration work after confirming anchoring and retrieval.

2020 · Jiangxi, China · Campus lakeCampus lake continuous water-quality monitoring
In January 2020, a fixed monitoring buoy was deployed for all-weather continuous measurement, with data transmitted to the monitoring center for online diagnosis and anomaly alerts.
2023 · Zhejiang, China · Pharmaceutical parkPharmaceutical industrial park drainage and river monitoring
In 2023, monitoring nodes were installed at stormwater outlets, river-entry discharge points and key river sections to track nutrients and core water-quality changes continuously.
2022 · Guangdong, China · YangjiangUnmanned boat multiparameter water survey
In August 2022, water-quality sensors were integrated with an unmanned boat for mobile, all-weather multiparameter monitoring.
What to confirm before configuring the buoy
Both models are highly configurable integrated platforms. Listed measurement ranges describe available sensor options, not a claim that every sensor is supplied as standard. The final package must be engineered for the real water, location, anchoring, communications, autonomy and data platform.
- 01Confirm target parameters, ranges, sensor count and real-water interferences
- 02Confirm depth, current, waves, anchoring, theft protection, collision risk and retrieval
- 03Confirm measurement/reporting intervals, cloudy-day autonomy, solar exposure and maintenance interval
- 04Confirm 4G/Modbus, cloud platform, alarms, data format and project acceptance requirements
Documents prepared after engineering confirmation
After receiving the parameter schedule, site and communication requirements, we can prepare a neutral configuration sheet, sensor compatibility matrix, buoy and anchoring recommendation, power and communication plan, commissioning checklist and quotation.
