River water-quality surveillance, gravity-fed rural water-supply supervision, and remote decentralized wastewater-treatment station control — representative reference IoT application frameworks, with further scenarios spanning reservoir flood monitoring, ecological observation, smart agriculture and urban hydrology.
Weather stations, temperature-humidity probes and ultrasonic anemometers form the sensing backbone of environmental monitoring grids.
Compact ultrasonic micro weather station delivers six environmental parameters from a single pole-mount package for ambient monitoring networks.
High-accuracy air temperature and relative humidity probe for stations, greenhouses, buildings and industrial environments.
No-moving-parts ultrasonic wind sensor providing low-maintenance wind speed and direction measurements for critical environmental stations.
This river water-quality monitoring reference application illustrates how our self-developed environmental sensors integrate with external professional water-quality probes. Traditional fixed-point sampling creates dangerous monitoring blind spots — sudden spikes in ammonia nitrogen or organic pollution from scattered domestic sewage may go undetected.
This reference system adopts our self-developed environmental sensors for environmental background monitoring, paired with external water-quality probes (pH, conductivity, NH₃-N, COD, total phosphorus, dissolved oxygen) for water-chemistry measurement. A three-layer IoT architecture — perception, network and application — combines fixed river-bank stations with mobile monitoring under a unified cloud platform. When any water-quality indicator exceeds national-standard limits, a spatio-temporal anomaly-detection algorithm automatically switches stations into intensive-sampling mode.
For hilly mountain rural communities, mountain-stream raw water often suffers from high turbidity during rainy seasons, without local purification or disinfection facilities. Conventional "coagulation-sedimentation-filtration" processes for large-scale water plants are cost-prohibitive and management-intensive for small-size rural waterworks.
This reference solution adopts gravity-driven low-flux ultrafiltration paired with a four-layer IoT supervision platform. Our environmental sensors deliver environmental background data (temperature, humidity, rainfall) plus water-level monitoring, while external water-quality probes measure turbidity and residual chlorine. The whole treatment process relies purely on terrain elevation difference with no pumping equipment; total installed power is approximately 150 W. PVDF hollow-fiber membranes operate at 12–16 L/(m²·h) to mitigate membrane fouling and extend chemical-cleaning intervals to 3–5 months. The IoT platform supports unattended plant operation with a reference direct-operating cost of around 0.058 CNY/m³.
Decentralized rural wastewater-treatment facilities commonly face operational challenges: highly variable inflow volumes, rainy-season inflow dilution lowering COD values and increasing complexity for carbon-source dosing, plus high costs for 24-hour on-site staffing at remote locations.
A three-tier remote intelligent-control system addresses these pain points. Our environmental sensors track environmental conditions and rainfall, while external process probes (DO, ORP, sludge concentration, flow) feed into a PLC unit. An Ethernet IoT terminal transmits data to the cloud over MODBUS TCP/IP, and a cloud platform converts data into control commands for pumps, aerators and dosing units. A genetic algorithm analyses historical dosing data to predict chemical dosage for next cycle, cutting total dosing volume by about 12% while keeping effluent within Class A standard. The reference process is A2O + MBR, 60–200 t/d, with aerobic DO of 4–6 mg/L and internal reflux of 2.2Q.
River water-quality surveillance, gravity-fed rural water-supply supervision, and remote decentralized wastewater-treatment station control are well-established IoT application frameworks in the environmental monitoring industry. Built on the standard three-tier IoT architecture (perception, network, and application layers), these systems can be integrated with third-party integrators' overall designs while incorporating our self-developed environmental sensors — micro-weather stations, temperature-humidity transmitters, and ultrasonic sensors. When combined with additional third-party peripherals (water-quality probes, PLC controllers, membrane water-purification units, and field actuation equipment), they enable fully unattended field monitoring and control.
