Dragino PS-LS LoRaWAN Air Water Pressure Sensor

The Dragino PS-LS series sensors are LoRaWAN Pressure Sensors for Internet of Things solutions. PS-LS can measure Air, Water pressure, and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.

The PS-LS series sensors include Thread Installation Type and Immersion Type, it supports different pressure range, which can be used for different measurement requirement.

The LoRa wireless technology used in PS-L allows devices to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

PS-LS supports BLE configuration and wireless OTA updates, which make users easy to use.

PS-LS is powered by solar powered + Li-ion battery;  it is designed for long-term use for up to 5 years.

Each PS-LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server, and it will auto-connect after powering on.
