PS-LB-I250 LoRaWAN Water / Liquid Pressure Sensor

The Dragino PS-LB-I250 is a LoRaWAN-enabled water and liquid pressure sensor designed for reliable hydrostatic pressure and liquid level monitoring in industrial, agricultural, and utility applications. Using an immersion-type pressure probe, it measures liquid pressure accurately and transmits data over long distances via LoRaWAN. With ultra-low power consumption and a high-capacity battery, it supports long-term, maintenance-free deployments in remote environments.
