Smart state detection with NB-IoT and LTE-M sensors
Adeunis DRY CONTACTS sensors detect (open/ closed) binary states without the need of active current in the monitored circuit, optimizing energy consumption. Sensor data is transmitted over NB-IoT/ LTE-M networks ensuring reliable connectivity and wide coverage, even in remote areas.
DRY CONTACTS can also be configured to work with LwM2M (Lightweight Machine to Machine) and MQTT (Message Queuing Telemetry Transport) standards, enabling users to configure remotely and optimize data consumption with each transmission. Transmission modes include periodic updates for status, even count and duration or event-based reporting triggered by the number of events or their duration.
A time counter measures how long a system remains in an ‘abnormal’ state while recording data, enabling you to quickly detect and address any issues. Thanks to its configurable inputs the sensor can operate simultaneously with up to 2 devices.
The low energy consumption, robustness and easy integration into IoT networks make them essential tools for optimising industrial processes, improving building management or monitoring public infrastructures.
