Dragino PS-LB LoRaWAN Air Water Pressure Sensor

Description

• Dragino PS-LB LoRaWAN Air Water Pressure Sensor
• Designed for Internet of Things solution
• Measure air or gas and water pressure
• Include Thread Installation Type and Immersion Type
• Ultra-low power consumption
• Support wireless OTA update firmware

The Dragino PS-LB LoRaWAN Air Water Pressure Sensor is designed for Internet of Things solution. PS-LB can measure Air, Water pressure, and liquid level and upload the sensor data via wireless to the 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 the 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 is powered by an 8500 mAh Li-SOCI2 battery (designed for long-term use up to 5 years). PS-LB supports BLE configuration and wireless OTA updates which make users easy to use. Each PS-LB 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 power on.
