Advanced environmental monitoring with NB-IoT sensors

Efento NB-IoT sensors

The Efento NB-IoT sensors deliver an advanced solution for long-term environmental monitoring and data acquisition across industrial, agricultural, and infrastructure applications. Leveraging NB-IoT technology, these sensors offer efficient, real-time data transmission while minimizing power consumption, enabling battery life of up to 10 years. Equipped with edge analytics, they process data locally to reduce transmission frequency and optimize performance. Fully configurable remotely, these sensors support over-the-air software updates and integrate seamlessly with the Efento Cloud platform or third-party systems, providing comprehensive insights and flexible data management for a wide range of applications.


Efento NB-IoT Pulse Counter

The Efento NB-IoT Pulse Counter allows for seamless integration with external 0–10 V and 4–20 mA sensors, making it ideal for monitoring pulse-based systems such as water, electricity, and gas meters. With edge analytics capabilities, the sensor processes data locally, reducing transmission frequency to extend battery life while maintaining accurate records.
