Remote data access and delivery requires a SIM card.

The ML-315 is a simple self-contained datalogger with an integrated solar panel. This makes it perfect for use as a weather station.
ICT can provide an external breakout box to more easily connect SDI-12 or RS485 sensors to the ML-315.

An example weather station setup could be:
Decagon VP-3, relative humidity, temperature and vapour pressure.
Decagon DS-2 Sonic Anemometer – Wind speed, Direction and Temperature.
SP-214 Pyranometer – Global shortwave radiation.
MPS-6 Soil water potential.
Rain Gauge.
