The Dragino PS-LS-T series sensors is powered by 8500mAh Li-SOCI2 battery or solar-powered + li-on battery , it is designed for long-term use up to 5 years. include Thread Installation Type Pressure Sensor
The PS-LS-T can measure Air, Water pressure and liquid level and upload the sensor data via wireless to the LoRaWAN IoT server.
The LoRa wireless technology used in PS-LS-T 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 while minimizing current consumption.
PS-LS-T supports BLE configure and wireless OTA update which make users easy to use.
Each PS-LS-T is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto-connect after powering on.
