LoRaWAN water quality total hardness sensor is a high-precision online monitoring device for water quality total hardness based on LoRa spread spectrum communication technology and powered by DC interface. It is designed specifically for industrial sites, computer rooms, and outdoor cabinets that require stable DC power supply. It can monitor the concentration of calcium and magnesium ions in water in real-time 7x24 hours, and transmit the data to the monitoring platform through a low-power wide area network over long distances. Its core value lies in solving the challenges of traditional wired monitoring wiring difficulties, high costs, and unstable Wi Fi/4G signals, with extremely low deployment costs and strong penetration rates. It is the core perception layer equipment for achieving intelligent and unmanned management of scenarios such as softened water treatment, boiler feedwater, and reverse osmosis systems.
Core advantages of the product:
1.DC interface design makes industrial power supply more convenient
Different from the regular battery powered version, this model
specifically adopts a DC/DC power interface and supports wide
voltage input. It can seamlessly connect to existing 24V or 12V
industrial power sources, PLC control cabinets, or outdoor solar
energy storage systems on site, without the need for frequent
battery replacement, ensuring that the equipment has a long-lasting
and uninterrupted endurance under harsh working conditions such as
high temperature and continuous operation, truly achieving
"one-time deployment, long-term operation".
2.LoRa wireless transmission, combining penetration and distance
Adopting LoRa modulation technology, it has excellent link budget.
In complex industrial parks, underground pipe galleries, or multi
story factories, signal penetration far exceeds traditional ZigBee
or Wi Fi. Even if the monitoring point is several kilometers away
from the gateway or in a closed computer room, data can still be
stably uploaded, significantly reducing the number of repeaters and
lowering the total cost of network construction.
3.High precision electrode, real-time feedback of total hardness
Built in durable ion selective electrode, combined with automatic
temperature compensation algorithm, can quickly respond to changes
in water hardness. The measurement data is accurate and reliable,
with errors controlled within industrial standards. Users can view
real-time instantaneous hardness values and change curves through
the platform, timely grasp the failure time of softened water resin
or fluctuations in raw water quality, and avoid pipeline blockage
or boiler damage caused by hard water scaling.
4.IP67 protection, able to handle harsh environments with ease
The whole machine adopts a fully sealed waterproof structure,
combined with a corrosion-resistant shell, with a protection level
of IP67. Whether it is a high humidity softened water workshop, a
chemical plant where acid and alkali gases evaporate, or an outdoor
rainwater immersion environment, it can effectively protect the
internal circuit and ensure the long-term stable operation of the
sensor.
5.Minimally cloud based, data-driven intelligent operation and
maintenance
Supports standard Modbus protocol and can quickly connect to
third-party DTUs or directly interface with mainstream IoT cloud
platforms. The platform supports over limit alarm, historical data
report export, and remote parameter configuration, enabling water
quality monitoring to move from "manual inspection" to "data-driven
decision-making", and helping enterprises save energy, reduce
consumption, and ensure safe production.
