Data Logger Comet U3631Msim – IoT Wireless Temperature and Humidity Datalogger with Connector for 1 External Temperature Probe, GSM Modem, Flat Rate SIM Card

• Measured values: Temperature and Relative Humidity (External temperature probe not included)
• Temperature measurement range: -20 to +60 °C
• Temperature range with the external probe: -90 to +260 °C
• Humidity measurement range: 0 to 100 %RH
• Dew Point measurement range: -90 to +60 °C

The Comet IoT wireless dataloggers are intended to measure physical quantities such as temperature, dew point, humidity and monitor two-state signals or count pulses. Upper and lower limits can be set for an alarm on each measurement channel. Recording can be performed continuously or at alarm time only. Built-in battery-operated GSM modem allows alarm indication and data transmitting.

Measurement and monitoring

• Temperature
• Humidity
• Dew point
• Two-state inputs
• Counter

Mobile Data loggers measure physical quantities such as temperature, dew point, humidity, and monitor also two-state signals or count pulses. The measuring interval can be set up from 1s to 24h. The measured value is shown on the LCD display as well as MIN / MAX value.

Alarm indication

• Exceeding alarm limits on the channel
• Device failure
• Battery condition
• Memory occupancy
• External power failure

For each measurement channel, you can set upper and lower limits. In case the limits are exceeded the alarm is indicated on the display, visually by LED or acoustically. Built-in GSM modem allows the sending of the alarm via SMS as a text message. Users can be also informed about device failure, battery and memory state, or external power failure. The device also supports Latched alarms – every alarm occurring in the device remains active until some operator’s action, irrespective of the measurement values (until the time of manual cancel).

Record

• Non-cyclic record mode
• Cyclic record mode (FIFO)
• Recording continuously
• Recording at the alarm time

Recording can be performed continuously or at alarm time only. Measured data can be stored in memory at intervals from 1s to 24h. Logging mode can be adjusted as non-cyclic when logging stops after filling the memory or cyclic, when the oldest recorded values are overwritten by new ones after the memory is full (first in first out). Up to 500, 000 values can be stored in memory.

Data transmitting via GSM

• Alarm indication via SMS as texts
• Keep alive texts
• Data collecting to Comet cloud and software via GSM

Built-in battery-operated GSM modem allows alarm indication and data transmitting. Data can be sent in the shortest interval of 5min to Comet database software or Comet cloud thru a data network. For saving battery life there is a function of data buffering to keep GSM modem in the sleeping mode for a longer time. Users can also set up ‘keep alive’ texts, which periodically inform of the current state of the device.

COMET Vision 2.0 – Analytic and Configuration Software

The recorded data can be transferred to a PC via USB cable or via GSM network for further analysis. Obtained values can be displayed in the form of a table or graph. Data and reports can be printed or exported for further processing. Comet Vision software 2.0 allows setting of device and simple data analysis. Comet database software allows collecting data from unlimited numbers of Comet devices and displaying measuring channels from unlimited number of devices on one screen. Comet cloud supports easy online access to measured data.
