16 == 1.1 ​ What is LPT01 LoRaWAN Temperature Transmitter ==
17
18
19 The Dragino LPT01 Food Grade LoRaWAN Temperature Transmitter is designed to monitor the temperature of different food environments. It supports reading PT100 probes and converting the value to temperature and uploading it to an IoT server via LoRaWAN protocol.
20
21 LPT01 supports (% style="color:blue" %)**Datalog feature**(%%). User can retrieve the sensor value via LoRaWAN downlink command.
22
23 LPT01 (% style="color:blue" %)**supports wireless OTA update**(%%) which make user easy to use.
24
25 LPT01 is powered by (% style="color:blue" %)**CR123A non-rechargeable battery**(%%) and target for long time use, these batteries can provide about 16,000 ~~ 70,000 uplink packets, which result in 2 ~~ 10 years battery life. After battery running out, user can easily open the enclosure and replace with CR123A batteries.
26
27 Each LPT01 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto-connect after power on.

To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the LPT01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is **20 minutes**.

126
127
128 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
129
130 The LPS8V2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.
