PS-LB-I3 LoRaWAN Water / Liquid Pressure Sensor

The Dragino PS-LB-I3 is a LoRaWAN-enabled water and liquid pressure sensor designed for accurate hydrostatic pressure and liquid level monitoring. Using an immersion-type pressure probe, it measures liquid pressure reliably and transmits data over long distances via LoRaWAN. Its ultra-low power design and high-capacity battery make it ideal for long-term, remote deployments.
