Overview :

LAS-604V4 is a temperature/humidity sensor that utilizes LoRaWAN to periodically report temperature/humidity. LAS-604V4 can also send an abnormal temperature alarm once environment temperature is out of predefined allowable range. LAS-604V4 is hourly report that temperature/humidity is reported or recorded every hour. In addition, LAS-604V4 will retrieve date time for synchronous from server at boot up which make sure the accuracy of report time period.

Features :

  • Slim design
  • Wide temperature measurement
  • Data logger and wireless transmission to server
  • Two operation report modes
  • High accuracy RTD thermometer probe
  • Easy to replace the battery without special tools.
  • Low power and long battery life
  • Easy settings for user from web configuration
