GSM datalogger can be configured to record from four binary inputs, or from two pulse and two binary inputs. If the input values exceed set limits, the device sends an SMS message or a JSON message via a 4G data connection. Values can also be sent to COMET Cloud, which is a complete monitoring, alarm, and analysis system. The regular sending of JSON messages to COMET Database can be adjusted; alarms are indicated locally by LED, LCD, and acoustic beeper. Recording is performed in a non-volatile electronic memory; data can be transferred to your PC via included USB-C cable.
