wireless data loggers
Battery powered WiFi datalogger The ML-017 data logger is similar to the ML-417 as well, but is lacking the cellular communication abilities.

This model is suitable for stand alone data logging or remote/wireless data logging by connecting it to an Iridium satellite transceiver or equipping it with a WiFi module.

The interesting priced ML-017 is a "byproduct" subject to availability, its a regular produced data logger with a switched-off cellular communication part, because that part did not pass our factory tests due to a malfunctioning or wrong/none assembled modem or RF component.
