LoRaWAN Water Quality Blue Green Algae Sensor


Adopts fluorescence detection technology: emits specific wavelength excitation light to stimulate phycocyanin (unique to cyanobacteria) to release characteristic fluorescence. Quantifies fluorescence intensity to accurately calculate cyanobacteria concentration, with effective differentiation from other algae. Built-in anti-interference algorithm and temperature compensation function reduce data errors caused by water turbidity, ambient light, and water temperature fluctuations.Communication: LoRaWAN low-power wide-area network technology, supporting long-distance wireless transmission (several kilometers coverage) for off-grid outdoor scenarios, reducing deployment costs; Protection: IP68 waterproof rating, made of corrosion-resistant materials for long-term submersion. Some models equipped with automatic cleaning brushes to prevent algae adhesion.

Core application scenarios:
  • Deployed in reservoirs, lakes, and other drinking water sources for 24/7 real-time cyanobacteria monitoring. Triggers alerts via LoRaWAN when concentrations exceed thresholds, allowing water plants to adjust purification processes in advance and avoid microcystin contamination.
  • Applied in fish ponds, shrimp tanks, and cage aquaculture. Provides real-time remote cyanobacteria data. When excessive algae growth threatens water oxygen depletion or toxin production, farmers take timely measures (water exchange, aeration) to reduce aquatic organism mortality and protect profits.
  • Used in park lakes, residential landscape ponds, and golf course water features. Enables easy installation without complex wiring. Managers monitor cyanobacteria levels remotely, taking timely action to control excessive algae growth, maintain clear water appearance, and prevent odor formation.
  • Applied in industrial cooling water and chemical wastewater treatment systems. Monitors cyanobacteria growth to enable proactive disinfection and algae removal, preventing pipe blockages and equipment corrosion, reducing water treatment costs and maintenance workload.

Key Values:

  • Breaks the limitations of wired monitoring with LoRaWAN low-power technology, enabling "wireless, long-term monitoring" in outdoor scenarios. Combined with high-precision fluorescence detection, it provides reliable and accessible water quality data.
  • Proactively warns of HAB and algal toxin risks, safeguarding drinking water safety, aquaculture product quality, ecological balance, and human health at the source.
  • Remote real-time data transmission and automated monitoring replace tedious manual sampling and testing, saving labor costs and enabling timely, data-driven water quality management decisions.
  • Supports the ecological protection and rational use of water resources, promotes the green and sustainable development of aquaculture, industrial water use, and other industries, achieving a win-win situation for economic and environmental benefits.
