- Model 1 - Surface Water Monitoring Data Logger



The RealSense 1 datalogger is an energy efficient and easily deployable telemetric logger which uses 3G or LPWAN (LoRa/Sigfox) communication technology to transmit measurement data (multiple times a day) to a portal, such as H2gO. Through the application of LPWAN communication technology the battery life of the data logger can be expanded to last for a multitude of years. The logger is extremely useful for absolute and relative level measurements as the housing of the logger contains an external air pressure compensation valve and an integrated baro sensor. Through configurable attachment possibilities the logger is highly suitable for a wide variety of sensors and their application areas.

Different sensors
The RealSense 1 has a rectangular shaped housing. The inlet of the logger allows for a variety of sensors to be attached, functioning on 4-20 mA, 0-10 V or pulse. The 3G edition also supports energy efficient sensor editions, with corresponding protocols. Parameters can, depending on the communication method, be set remotely and independently. The 3G edition supports the function of loading new software for the logger remotely.

Communication Methods
The RealSense 1 datalogger is compatible with two types of communication methods; 3G or LPWAN (See box on the right). The frequency of the measurement intervals and the parameters that are measured and stored determine which method of communication is the best for each location. When the LPWAN edition is chosen you can select a local/national provider or create your own LoRa/Sigfox network.

Increased battery life
The battery life of the loggers is determined, for the largest part, by the amount of times that the communication module is addressed to and the measurement/data logging frequency. The low-power communication methods LoRa and Sigfox have the advantage that the battery life is almost twice as long as the 3G edition. On hourly logging basis the battery life can be up to 5 years. The RealSense 1 data logger can, besides the use of batteries, also be equipped with a solar panel or the logger can be connected to regular AC.

Large data storage capacity
The RealSense 1 has a micro SD-card for extra storage capacity. This stores the data in case the connection fails, which assures the availability of all the data. When the communication model is shut off, it functions as a semi-automatic logger. In this case the data is stored on the SD-card and can be gathered manually on site.
