Overview :

LAS-604V3 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. The temperature measurement is through PT100 probe. For forcing various requests of demand, LAS-604V3 supports two operation modes, mode A and mode B. Mode A is hourly report that temperature is reported or recorded every hour. Mode B supports temperature measurement every 30 seconds, 1 minute or 2 minutes, depending on setting. In addition, LAS-604V3 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
  • 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
