Product Description

The Geolux SmartObserver is a datalogger explicitly designed for environmental monitoring applications. It has an integrated MPPT battery charger that can charge various chemical batteries directly from the solar panel or wind generator. The data logger has very low power consumption and three digitally controlled power outputs for powering sensors and other equipment, enabling a more extended battery autonomy even with a smaller battery. Integrated modular communication subsystem enables versatile communication interfaces ranging from the GSM/GPRS modem, LoRaWAN IoT communication, or modern IoT satellite communications. Each logger can be tailored to meet the specific needs of customers and the available infrastructure. Communication with instruments, sensors, and other equipment can be implemented using one of many serial communication interfaces (RS-232, RS-485 Modbus, CAN, SDI-12) or using analog current or voltage inputs. Integration of a power distribution system and MPPT charger enables easier monitoring as each logger will always report solar voltage, charging current, battery voltage, internal temperature, humidity, and many additional system health parameters.
