SmartObserverPlus

Datalogger

The GeoLux SmartObserverPlus is a powerful datalogger designed specifically for environmental monitoring applications.

It easily integrates with various instruments and sensors, offering RS-232, RS-485 Modbus, SDI-12, and CAN serial communication lines. It also includes four 24-bit analog inputs supporting both voltage and current measurement modes, and four digital inputs that can operate in pulse and frequency counter modes. Additionally, the onboard Ethernet interface allows for connection to instruments equipped with Ethernet.

The SmartObserverPlus features a modular communication subsystem, providing flexible options such as GSM/GPRS, LoRaWAN IoT, and modern satellite communication interfaces. For available options, refer to the Product Table on the previous page.

Designed for use in remote areas, the datalogger includes an integrated Maximum Power Point Tracking (MPPT) battery charger and three digitally controlled power outputs for managing power supply to instruments. The datalogger itself consumes extremely low power, with less than 1 mA used in sleep mode between measurements.

Configuration is straightforward via the GeoLux PC application. Most users can configure the datalogger through the intuitive UI, while advanced users can leverage the built-in MicroPython engine to write custom Python scripts for controlling the datalogger.
