PS-LB D11 LoRaWAN Differential Pressure Sensor -200 to 200Pa Node 868MHz

The PS-LB D11  LoRaWAN differential pressure sensor is ideal for the precise monitoring of pressure differences in various applications. This sensor is perfect for you if you want to improve the efficiency and safety of your systems. You can use it to monitor ventilation systems in buildings, detect full filters, or monitor heating systems. By using the LoRaWAN protocol, it enables wireless data transmission, making it particularly flexible and versatile. With its ultra-low power consumption and Bluetooth configuration capability, it offers you a reliable and long-lasting solution. This sensor node is the third generation from Dragino and offers a mature LoRaWAN stack and application software. You can use the pre-installed software for your IoT projects or flexibly adapt the software to different requirements.

Each sensor is 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 after being powered on if network coverage is available.
