429MHz Band LoRa Small Wireless Module for Water Quality Measurement

Water quality measurement achieved over long-distance wireless communication exceeding 10 km.

In the environmental monitoring industry, there is a demand for the accurate collection of water quality data from rivers and lakes. Particularly in remote or hard-to-access locations, real-time data acquisition for water quality measurement is crucial. Our 429MHz band LoRa small wireless module enables long-distance communication and low power consumption, allowing for data collection from water quality measurement sensors even in areas where traditional wireless communication has difficulty reaching. 【Use Cases】 * Water quality monitoring of rivers, lakes, and dams * Water quality measurement in remote locations * Data collection from underground facilities 【Benefits of Implementation】 * Extensive data collection through long-distance communication of over 10km * Battery operation due to low power consumption * Rapid situation assessment through real-time data acquisition

Applications/Examples of results

**Applications** Ideal for IoT implementation in **"areas where wireless signals have not reached until now,"** such as water level monitoring of rivers and dams, data transmission from inside manholes, environmental management of greenhouses, and infrastructure diagnostics. It is particularly effective for data collection from buildings, mountainous areas, and underground facilities where signals in the 2.4GHz and 920MHz bands are easily obstructed. With low power consumption and the capability for battery operation, it is optimal for telemetry in fields where long-term maintenance is difficult, as well as serving as the core of smart agriculture and disaster prevention monitoring infrastructure covering wide areas.
