DRAGINO · Sensor · LoRa · LoRaWAN 0~20mA, 0~ 30v sensor LoRaWAN Analog Sensor · PS-LB-NA-EU868-12

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

The PS-LB 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-LB allows device 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-LB supports BLE configure and wireless OTA update which make user easy to use.

PS-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

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

This sensor has a waterproof (IP68) M12 opening for external probes. For the measurement of air or water pressure please use the following items: 217626, 217627 or 217628
