ML-417 LTE-M & NB-IoT Data Logger

Solar powered LTE-M & NB-IoT data logger Solar powered LTE-M & NB-IoT data logger The ML-417 data logger is a small, low power, cost effective data logger with or without a built-in cellular modem (LTE-m & NB-IoT). This small data logger, is further provided with an internal temperature sensor, 8GB micro SD card and a 2FF SIM card slot. The data logger is available with several power provisions e.g. a 3.6 Volt Lithium batteries, 8..28V DC input, 12V solar panel input or integrated solar panel with battery charger.

The data logger can acquire physical signals by 2 current loop inputs, 2 voltage inputs, 1 potentiometer input and 3 digital inputs. More or special inputs can be added by means of internal stackable option boards. The data logger is provided with one serial port to capture measurements from ASCII, MODBUS, NMEA or SDI-12 compatible sensors. External sensors can be powered by the data logger itself, to prevent them to consume power while the data logger is a sleep. Up to 8 mathematical channels are available to calculate meaningful engineering values derived from sensor input values (e.g. to calculate dissolved oxygen in saline water). Supports up to 8 aggregation channels (e.g. to record 2 or 10 minute wind speed averages sampled at 1Hz).

Logged data can, when equipped with a cellular modem, be pushed to a server by HTTP(S), FTP(S), secure TCP or MQTT(S) at configurable intervals.

The ML-417 is available in several editions and with or without cellular modem: When equipped with the integrated solar panel a complete self providing remote monitoring station can be arranged, all you need is a logger and applicable sensor(s). This self providing cellular logger is costs saving, because you don't need: a) solar panels, b) big batteries, c) cellular modem and d) encapsulating cabinet.
Accessories 1) FTPS (TLS Explicit)
2) 60mA if no external sensors need to be powered.
3) <1 sec. if external sensors are responsive and don't require time to "warm up".
4) Batteries not included.
