Overview :

LAS-604V3 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. Built-in the LCD Display, the temperature measurement is through PT100 probe. It could support ultra-low temperature measurement condition in specific application such as medical cold train. In addition, LAS-604V3 will retrieve date time for synchronous from server at boot up which make sure the accuracy of report period.

Features :

  • Slim design
  • Wide temperature measurement
  • Data logger and wireless transmission to server
  • 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
