PS-LS I2 LoRaWAN Submersible Pressure Level Sensor 2m with Solar

The PS-LS I2 Submersible Pressure Level Sensor is a state-of-the-art sensor specifically designed for IoT solutions. This model uses a combination of solar cells and a supporting battery to ensure optimal performance and durability outdoors. It can convert different pressures at various liquid depths into measurement data, thus measuring the depth of the liquid. Equipped with LoRaWAN technology, this sensor can measure water pressure and 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, operation is extremely easy. The wireless part of the node is based on the SX1262, allowing data transmission over very long distances at low data rates. This ensures exceptionally long range, high interference resistance and optimized 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 being powered on when network coverage is present.
