Applications
		Fisheries We employ innovative solar-powered and maintenance-free water quality monitoring instruments. These instruments monitor parameters such as dissolved oxygen, water temperature, pH, salinity, ammonia nitrogen, and nitrate nitrogen. Additionally, they control aeration machines, feed dispensers, as well as inlet and outlet valves. Operating seamlessly in outdoor and humid environments, these systems provide comprehensive 24/7 monitoring and early warning capabilities, ensuring aquaculture safety while reducing production costs and maintenance expenses.

		Agriculture We utilize an innovative standalone multi-parameter water quality monitoring system. This system enables real-time monitoring, providing continuous and comprehensive data collection and analysis of water quality. By enhancing crop yields and improving product quality, it ensures lower operational costs and maintenance expenses. Through mobile and wireless communication, there is no need to collect data on-site. When monitoring data reaches alarm levels, data upload frequency can be accelerated for immediate situational monitoring.

		Drinking Water We offer a reliable and durable product combination that provides urban water management with powerful decision-making information. Our system enables real-time alerts, optimizing overall scheduling and maximizing the drainage capacity and self-recovery resilience of infrastructure. It effectively reduces stormwater overflows and unauthorized sewage discharges, ensuring the safety and cleanliness of drinking water.

		Sewage Discharge Monitoring We utilize cutting-edge wireless communication, ultra-low power consumption, and long-lasting operation technology, including IP68 waterproofing up to 5 meters. Our system monitors water intakes from rivers, tap water, and irrigation channels. In case of any water quality abnormalities, immediate alerts are issued, and water samples are automatically collected. This enables effective tracking of illegal discharges and prevents pollution escalation, ensuring public safety and the well-being of the community.

		Industrial Processes We adopt innovative low-power technology in an intelligent multi-parameter water quality analyzer that requires minimal maintenance and can be instantly deployed. It enables continuous monitoring of wastewater treatment equipment and water quality, providing round-the-clock surveillance throughout the year to ensure that water quality meets the required standards while reducing maintenance costs. In the event of equipment malfunctions or abnormal water quality, the system can immediately issue alerts, enhancing our ability to respond promptly. This will contribute to the smooth and efficient operation of wastewater treatment processes.

		Industrial Processes We offer a precise and highly reliable smart water quality monitoring solution for industrial processes. Our product combination provides stability and durability, ease of operation, and eliminates the need for reagents or consumables. It automatically and instantly collects and analyzes all water quality data during the production process, optimizing process control to effectively enhance production efficiency and quality while reducing production costs.

Differences Between HMI, Traditional Displays, RTU/PLC Systems, and Data Loggers

Comparison Item	HMI Water Quality and Flow Controller	Traditional Display / Panel Meter	RTU / PLC System	General Data Logger
Product Positioning	Remote monitoring and control platform for water quality, flow, water level, and water pressure	On-site value display or single-point instrumentation	Automatic control and on-site monitoring system	Data storage and basic data upload
Monitoring Parameters	Water quality, flow, water level, and water pressure; supports trend charts and alarms	Mostly displays single or limited parameters	Depends on external modules and programming	Mostly used for a single sensor or limited channels
Sensor Integration	RS485/Modbus RTU, connectable to SMR, MAX, H2O, and I/O modules; HMI2 can connect up to 8 SMR sensors	Requires additional converters or controllers	Can be integrated, but requires engineering and programming configuration	Usually limited in channels and expandability
Communication Methods	4G, NB-IoT, LoRa, satellite, WiFi, Ethernet, and RS485	Usually has no remote communication or requires additional modules	Depends on communication modules and engineering integration	Mostly based on 4G or a single communication method
Data Logging	Built-in 2,000,000 cyclic records, supporting scheduled logging, alarm logging, and accelerated logging	Usually does not provide complete data logging functions	Requires database or SCADA design	Provides logging functions, but control and display capabilities are weaker
Disconnection Handling	Automatically stores data when disconnected and retransmits data after communication is restored	Usually has no retransmission mechanism	Requires system design	Depends on the product
Alarms and Control	Four-level alarms, SMS notifications, contact output, IF_THEN_ELSE logic, schedules, and manual control	Mostly limited to on-site alarms or basic outputs	Comprehensive functions, but requires programming and wiring	Mostly provides basic alarm notifications
Cloud Platform	Can be integrated with the AQWEB cloud management platform and AQNET mobile APP	Usually requires separate setup	Requires integration with SCADA or cloud systems	Mostly uses a fixed platform or basic interface
Data Integration	Supports Modbus TCP, FTP/SFTP, MQTT, RESTful, HART, LoRa, OPC UA, and other interfaces	Limited integration capability	Customizable, but with higher cost	Mostly uses fixed formats or APIs
On-Site Operation	4.3-inch or 7-inch color LCD touch panel, displaying values, units, status, and alarms	Mainly for on-site display	Requires HMI/SCADA screen design	Usually does not provide a complete on-site operation screen
Backup Power Supply	Supports 12 VDC and 90–240 VAC; HMI2 can be equipped with an optional 3.6 VDC 80 AH rechargeable lithium battery	Depends on the panel power supply design	Usually requires stable mains power and UPS	Depends on the product
