Solar LoRaWAN water total hardness sensor real-time monitor


LoRaWAN solar water quality total hardness sensor is an all-in-one device integrating water quality data collection, real-time monitoring and wireless transmission. It features high energy efficiency and is ideal for IoT applications.

The sensor uses a patented calcium-magnesium ion electrode. Its internal reference solution diffuses slowly through the microporous salt bridge under a pressure of at least 100KPa (1Bar), providing a highly stable reference system and longer service life than ordinary industrial electrodes. Paired with automatic temperature compensation, it is especially suitable for long-term 24/7 online water quality monitoring.

It supports the standard LoRaWAN protocol with long-distance signal transmission, enabling stable and efficient data delivery to remote receivers.


This LoRaWAN wireless sensor is specially used to measure total water hardness expressed as CaCO₃.

Functional features

It adopts a PVC-based calcium-magnesium selective electrode for testing total hardness in water (calculated as CaCO₃), with temperature compensation to ensure fast, simple, accurate and economical testing.

Environmental adaptability

With temperature compensation function, it effectively resists interference from ambient temperature changes and ensures stable operation in complex environments.

Data accuracy

Automatic temperature compensation technology reduces environmental influence, providing more accurate and reliable water hardness data for decision-making.

Connection method

The sensor connects to a LoRaWAN collector via an aviation connector, allowing quick and easy installation.

Transmission advantage

LoRaWAN wireless communication realizes stable data transmission without extensive cabling, greatly reducing construction and maintenance costs.

Application scenarios

Widely used in industrial wastewater, surface water, drinking water, seawater monitoring, and online water quality analysis in industrial production processes.
