1. Introduction

1.1 What is LHT52 Temperature & Humidity Sensor

The Dragino LHT52 Temperature & Humidity sensor is a Long Range LoRaWAN Sensor. It includes a built-in

Temperature & Humidity sensorand has a USB Type-C sensor connector to connect to external sensors such

as external Temperature Sensor.

LHT52 senses environment temperature and humidity and send these values via long-range wireless

LoRaWAN protocol. It targets professional wireless sensor network applications such as food service, smart

metering, smart cities, building automation, and so on.

LHT52 supports2 x AAA batteriesand works for a long time up to several years. Use can replace the batteries

easily after they are ﬁnished.

LHT52 is fully compatible with LoRaWAN v1.0.3 protocol, it can work with standard LoRaWAN gateway.

LHT52 supportsDatalog featureto make sure users won't miss sensor data. It records sensor value for every

uplink. These values can be retrieved by LoRaWAN server via downlink command.

LHT52 supportstemperature alarm feature. It can uplink alarm in a short interval while temperature exceeds

preset limits.

*Battery life depends how often to send data, please see battery analyzer.

1.2 Features

• Wall Attachable.

• LoRaWAN v1.0.3 Class A protocol.

• Built-in Temperature & Humidity sensor

• Optional External Probe

• Frequency Bands: CN470/EU433/KR920/US915/EU868/AS923/AU915

2. Operation Mode

2.1 How it work?

Each LHT52 is shipped with a worldwide unique set of LoRaWAN OTAA keys. To use LHT52 in a LoRaWAN

network, user needs to input the OTAA keys in LoRaWAN network server. After this, if LHT52 is under this

LoRaWAN network coverage, LHT52 can join the LoRaWAN network and start to transmit sensor data. The default

period for each uplink is20 minutes.

2.2 How to Activate LHT52?

1. Open enclosure from below position.

User can check LED Status to know the working state of LHT52.

2.3 Example to join LoRaWAN network

This section shows an example for how to join the TheThingsNetwork LoRaWAN IoT server. Usages with other

LoRaWAN IoT servers are of similar procedure.

Assume the DLOS8 is already set to connect to TTN V3 network. We need to add the LHT52 device in TTN V3

portal.

Step 1: Create a device in TTN V3 with the OTAA keys from LHT52.

Each LHT52 is shipped with a sticker with the default DEV EUI as below:

Enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:

Add APP EUI in the application.

choose to create the device manually.

Default mode OTAA

Step 2: Use ACT button to activate LHT52 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.
