General Description
Lansitec precision platinum temperature sensor is based on
the advanced LoRa modulation and powered by lithium
battery with 6-year operation time. It is cost effective
LoRaWAN end device for a variety of application. It's long
operation time offers low maintenance and is ideal for
industry use. Sensor work mode can be adjusted via LoRa
network.
Lansitec sensors family is fully compatible and plug & play
for LoRaWAN network operation.
Lansitec sensors can also work with Lansitec Wireless Data
Transfer Unit (P/N: 100-00175) for low cost deployment.
Please contact us for further information.

Application Information
2.1 Function
The sensor works in OTAA and Class A mode. DEVEUI, APPEUI and APPKEY are stored in the sensor
and is necessary for joining a network. DEVEUI is labeled at the back of the device. APPEUI, APPKEY
should be provided by each application. Lansitec will help to configure this before shipping.
After power on and join the Lora network, sensor will send registration message to Application
Server(AS). If AS doesn’t reply, sensor will retry for 3 times before switching to default mode
(periodically report mode). Configuration information of the sensor is included in this registration
message for AS to validate.
Sensor starts to work after receiving acceptance response or no AS reply after 3 times registration
trial. Temperature will be reported to AS periodically. The duty cycle is configurable by commands
from AS. Temperature acquisition and report period is 5 minutes by default.
According to LoRaWAN specification, downlink response time is decided by uplink duty cycle, user
should refer the needed response time to choose uplink duty cycle. Detailed downlink and uplink
definition are described below.
