PS-LB I2 Dive Pressure Fill Level Sensor 2m

The PS-LB I2 Submersible Pressure Level Sensor is a state-of-the-art sensor specially developed for IoT solutions. It can convert different pressures at various depths of liquids into measurement data to measure the liquid's depth. Equipped with LoRaWAN technology, this sensor can measure water pressure as well as liquid level and wirelessly transmit 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 BLE configuration and wireless OTA updates, the operation is very easy. 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 data transmission over very long distances at low data rates. This ensures exceptional range, high interference immunity, and optimizes power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB Flash, and 64KB RAM, the PS-LB is prepared 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 being turned on when network coverage is available.
