PS-LB I4 Dive Pressure Level Sensor 4m

The PS-LB I4 Submersible Pressure Level Sensor is a state-of-the-art sensor specifically designed for IoT solutions. It can convert different pressures at various depths of fluids into measurement data, thus measuring the depth of the fluid. Equipped with LoRaWAN technology, this sensor can measure water pressure as well as fluid level and wirelessly send the data to a LoRaWAN IoT server. The sensor is available in various pressure ranges, making it suitable for different measurement requirements. Thanks to the BLE configuration and wireless OTA updates, 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 allows the transmission of data over very long distances at low data rates. This ensures exceptionally wide range, high immunity to interference 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 comes pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically connects upon powering up, if network coverage is present.
