www.dragino o.com 1. Introductio on 1.1 What is WTTS Temperaature & Hum midity Sensor The WTS Temperrature sensor isa Long Ran nge LoRaWAN NSensor. It inccludes a builtt-in Temperatture senssor. The WTS allows users u to send data and reaach extremelyy long rangess. It provides ultra-long ran nge spreead spectrum communicattion and high h interference e immunity whilst w minimizzing current conssumption.
www.dragino.com WTS supports Data-log feature, it will store the data when there is no LoRaWAN network and upload them to LoRaWAN server when there is LoRaWAN network coverage again WTS has a built-in 3.8Ah non-chargeable battery which can be used for long term. WTS is full compatible with LoRaWAN v1.0.3Class A protocol, it can work with standard LoRaWAN gateway. 1.2 Features Wall mountable, in place / out of place detection LoRaWAN v1.0.3 Class A Protocol Built-in 3.

This mode is used for storage and shipping to save battery life. Working Mode: In this mode, WTS will work as LoRaWAN Sensor to Join LoRaWAN network and send out sensor data to server. Between each sampling/transmit periodically, WTS will be in STOP mode (IDLE mode), in STOP mode, WTS has the same power consumption as Deep Sleep mode.
www.dragino o.com ume the LG30 08 is already set s to connecct to TTN V3 network . Wee need to add d the WTS device Assu in TTTN V3: Step p 1: Create a device d in TTN N V3 with the OTAA keys frrom WTS.
www.dragino.com User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot: Add APP EUI in the application.
www.dragino.com Add APP KEY and DEV EUI Step 2: Use ACT button to activate WTS and it will auto join to the TTN V3 network. After join success, it will start to upload sensor data to TTN V3 and user can see in the panel.
www.dragino.com 2.4 Uplink Payload The uplink payload includes totally 11 bytes. Uplink packets use FPORT=2 and every 20 minutes send one uplink by default. After each uplink of WTS-10 and WTS-11, the blue LED will flash once If the PT100 is not connected, the red LED will flash once every time the WTS-11 uplinks Normal Uplink Payload. Total 11 Bytes.
www.dragino.com External Temperature (Temp_PT100): 2 bytes ( For model WTS-11 only) Temperature: 0x0ABB/100=27.47℃ Temperature: (0xF5C6-65536)/100=-26.18℃ In WTS-10, WTS-12, these 2 bytes are always 00 00 Open Duration & Open Timeout Alarm: 2 bytes ( For model WTS-12 only) Bits 15 14 [13:0] Value: Reserve Timeout Alarm Bright Duration Timeout Alarm: This bit indicates if the bright detection exceeds certain time. The default timeout is 5 minutes.

If WTS didn’t got the ACK, WTS will consider out of LoRaWAN service and mark the Status None ACK Flag bit to 1, meanwhile, WTS will record this unarrived packet. If WTS got the ACK from LoRaWAN server, WTS will consider it is in LoRaWAN service.
www.dragino.com WTS will uplink this payload when in LoRaWAN service Uplinkpayload: 8E0F410A840000617801848E0F410A82000617801C008E0F410A81000617801FC8E0F410A8000 00617802388E0F410A7D000617802748E0F410A7D0000617802B08E0F410A7B0000617802EC8E 0F410A7A0000617803288E0F410A790000617803648E0F410A770000617803A0 Where the first 11 bytes is for the first entry: 8E0F410A84000061780184 BAT:0x8E0F=1000 1110 0000 1111 00 1110 0000 1111/1000=3.599V Temp_TMP117:0x0A84/100=26.
