Efento NB-IoT Wireless Differential Pressure Logger

Smart, wireless monitoring of pressure differences – with no extra hardware.

The Efento NB-IoT Wireless Differential Pressure Logger is designed to accurately measure pressure differences between two spaces. Ideal for hospitals, cleanrooms, laboratories and production halls where constant control of air pressure is essential for safety and quality.

Thanks to NB-IoT technology, the logger sends its data directly via the mobile network. No routers or gateways are needed. Via Bluetooth Low Energy (BLE), the sensor can easily be configured with a smartphone and integrated with Efento Cloud or any other cloud platform.
