LoRa smart water meter supports both automatic and manual networking, achieving an optimal balance between reliable communication and low power consumption. The smart remote-transmission water meter module uses current ultra-low-power MCU, RF chip, and LoRa spread spectrum frequency hopping technology—greatly improving transmission efficiency while maintaining low energy consumption, with a wireless transmission distance of 2~5 km in open areas.
