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
