Delta Logger DL2 LoRa SDI12

Delta Logger DL2 LoRa SDI12

LoRa / SDI 12 Logger
The Delta LoRa Logger is a logging device with 2 analog inputs, one SDI12 and one counter interface. The device is battery powered and functions as a stand-alone data logger, collecting data from its sensors and transmitting the data through LTE Cat M1/Cat NB1, EGPRS, GPRS, LoRaWan or Sigfox at programmable intervals. It can also be configured as Gateway collecting data from remote sensors using LoRa modulation.
