    The KISTERS IoTa 2DL 12V sensor node acquires and logs sensor data locally, ensuring no data loss, and transmits it through TLS-protected wireless connectivity using MQTTS for seamless integration with your data-management systems.

    The IoTa 2DL 12V integrates easily into existing data-acquisition systems and operates for extended periods from nominal 12 V DC, including solar setups. It supports SDI-12 and counter inputs and reduces power consumption through processor hibernation and on-demand SDI-12 sensor powering.

    The IoTa 2DL 12V is equipped with an integrated LTE CAT M1 (LTE-M) modem for remote data transmission and an internal stubby antenna.

    Configuration is possible locally using the free KISTERS HyComm Windows software.

    Easy installation

    Thanks to its compact form factor, the IoTa 2DL 12V fits easily into existing cabinets. Input signals are connected through external push-terminal blocks – no need to open the housing. Ideal to build inobtrusive monitoring stations.

    Monitoring Networks

    Each IoTa 2DL 12V sensor node adds IoT connectivity to set-ups with up to eight SDI-12 sensors plus one pulse-output sensor.
