Referencia interna: 5221

The Efento 4–20 mA Sensor Interface makes it possible to easily connect analog sensors to the cloud. The device is equipped with 2 × 4–20 mA analog inputs, allowing simultaneous operation with up to two external sensors. The connected sensors can be powered via the device's internal battery or via an external power source.

The measurement data is transmitted as 4–20 mA current values and can be displayed in the Efento Cloud or another cloud platform, or converted to other units of measurement.

Thanks to NB-IoT connectivity, the device sends data directly over the mobile network, without needing additional hardware such as routers or gateways. Configuration is quick and easy via a smartphone with Bluetooth Low Energy (BLE).
