Pipe pressure sensors can be used to monitor the pressure of liquids or gases in the pipes / tanks. They are ideal for monitoring and preventing leakages from water pipes or any other pipe-based systems. The second popular use case of pressure sensors is monitoring of tank level based on the liquid’s pressure.

Efento NB-IoT sensors transmit the data over cellular network (Narrowband IoT) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT sensors can be integrated with any cloud platform.
