  • Page 2: Introduction

    Illuminance sensor. The LHT65N-E5 allows users to send data and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on.

  • Page 3: Connect Lht65N-E5 To Iot Server

    2.1 How does LHT65N-E5 work? LHT65N-E5 is configured as LoRaWAN OTAA Class A sensor by default. Each LHT65N-E5 is shipped with a worldwide unique set of OTAA keys. To use LHT65N-E5 in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65N-E5.

  • Page 4: Example To Join Lorawan Network

    This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Use with other LoRaWAN IoT servers is of a similar procedure. Assume the LPS8v2 is already set to connect to TTN V3 network (https://eu1.cloud.thethings.network) , So it provides network coverage for LHT65N-E5. Next we need add the LHT65N-E5 device in TTN V3: 2.3.1 Step 1: Create Device n TTN...

    2.3.2 Step 2: Activate LHT65N-E5 by pressing the ACT button for more than 5 seconds. Use ACT button to activate LHT65N-E5 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.

  • Page 7: Decoder In Ttn V3

    2.4.1 Decoder in TTN V3 When the uplink payload arrives TTNv3, it shows HEX format and not friendly to read. We can add LHT65N-E5 decoder in TTNv3 for friendly reading. Below is the position to put the decoder and LHT65N-E5 decoder can be download from here: https://github.com/dragino/dragino-end-node-decoder (https://github.com/dragino/dragino-end-node-decoder)

  • Page 8: Ext Value

    1: Set time ok，0: N/A. After time SYNC request is sent, LHT65N-E5 will set this bit to 0 until got the time stamp from the application server. Unix Time Request: 1: Request server downlink Unix time, 0 : N/A. In this mode, LHT65N-E5 will set this bit to 1 every 10 days to request a time SYNC.

Add Datacake: Select default key as Access Key: In Datacake console (https://datacake.co/ (https://datacake.co/) ) , add LHT65 device. wiki.dragino.com/xwiki/bin/view/Main/User Manual for LoRaWAN End Nodes/LHT65N-E5 LoRaWAN Temperature_Humidity %26 Illuminance Se… 9/28...

  • Page 10: Datalog Feature

    2.6 Datalog Feature Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LHT65N-E5 will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from LHT65N-E5.

  • Page 11: Unix Timestamp

    Once LHT65N-E5 Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LHT65N-E5. If LHT65N-E5 fails to get the time from the server, LHT65N-E5 will use the internal time and wait for next time request (AT+SYNCTDC to set the time reques period, default is 10 days).

  • Page 12: Datalog Uplink Payload

    For example, downlink command 31 5FC5F350 5FC6 0160 05 Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00’s data Uplink Internal =5s，means LHT65N-E5 will send one packet every 5s. range 5~255s. 2.6.5 Datalog Uplink payload The Datalog poll reply uplink will use below payload format.

    4.10 Auto Send None-ACK messages Feature: LHT65N-E5 will wait for ACK for each uplink, If LHT65N-E5 doesn't get ACK from the IoT server, it will consider the message doesn't arrive server and store it. LHT65N-E5 keeps sending messages in normal periodically. Once LHT65N-E5 gets ACK from a server, it will consider the network is ok and start to send the not-arrive message.

  • Page 18: Battery & How To Replace

    The minimum Working Voltage for the LHT65N-E5 is ~ 2.5v. When battery is lower than 2.6v, it is time to change the battery. 5.2 Replace Battery LHT65N-E5 has two screws on the back, Unscrew them, and changing the battery inside is ok. The battery is a general CR17450 battery (3.0v). Any brand should be ok. 5.3 Battery Life Analyze Dragino battery-powered products are all run in Low Power mode.
