PS-LB I2 Dive Pressure Fill Level Sensor 2m

The PS-LB I2 Submersible Pressure Level Sensor is a state-of-the-art sensor specifically designed for IoT solutions. It can convert different pressures at different depths of liquids into measurement data, thus measuring the depth of the liquid. Equipped with LoRaWAN technology, this sensor can measure water pressure as well as the liquid level and wirelessly send the data to a LoRaWAN IoT server. The sensor is available in various pressure ranges and is therefore suitable for different measurement requirements. Thanks to the BLE configuration and wireless OTA updates, operation is child's play. Equipped with an 8500mAh Li-SOCI2 battery, the sensor is designed for long-term use of up to 5 years. The wireless part of the node is based on the SX1262, which enables the transmission of data over very long distances at low data rates. This ensures an exceptionally wide range, high interference resistance and optimises power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB flash and 64KB RAM, the PS-LB is ready for all types of projects.

Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically connects after power up if network coverage is available.
