The 3004ML/3006ML datalogger utilises the LoRa communication system, LoRa WAN network, which utilises MQTT as its method of sending sensor data from the field to the Neon Server. The NRL LoRa operates in what Unidata calls LoRa Mode 2. In this mode, sensors are read by the logger according to the scheme. A set of short data packets will be sent, as set by logging interval, to the LoRa WAN gateway over either private or public LoRa network. LoRa WAN gateway transfers data packets to Neon Server using Ethernet, cellular or satellite network. The LoRa Wan system has a typical range of to 5 Km, the range reduces in built up areas depending on building density and increases where there is line of sight and with use of a larger antenna. The 3004ML/3006ML is housed in a polycarbonate case which has a smaller form factor than the standard metal enclosure 3004. It connects to sensors in the field, collects readings from those sensors, logs the sensor data and provides control functions.Using Starlog V4 PC software loggers are programmed with a scheme to specify which sensors to log and how often to store readings. It also provides information about memory and battery duration for that scheme. Control outputs are also set up in the scheme by setting up custom events. A wide range of sensor types are supported including analog sensors, frequency counters, digital inputs as well as Modbus and SDI-12 instruments. Control of external equipment (such as triggering a relay when a user defined event occurs, or initiating a shutdown), can be accomplished via Open Drain FET output. Sensors are connected to the logger via pluggable terminal blocks, allowing for easy removal of the logger if servicing is required.
