26 == 1.1 What is LHT65N-PIR Temperature,Humidity & PIR Sensor ==
27
28 The Dragino (% style="color:blue" %)**LHT65N-PIR Temperature, Humidity & PIR sensor**(%%) is a Long Range LoRaWAN Sensor.It includes a (% style="color:blue" %)**built-in Temperature & Humidity sensor**(%%) and has an (% style="color:blue" %)**external PIR Probe**(%%)**.** LHT65N-PIR can detect environment Temperature & Humdity, it also detects (% style="color:blue" %)**People Activity**(%%) via PIR probe and them send these info to LoRaWAN IoT Server.
29
30 The LHT65N-PIR 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.

81 = 2. Connect LHT65N-PIR to IoT Server =
82
83 == 2.1 How does LHT65N-PIR work? ==
84
85 LHT65N-PIR is configured as LoRaWAN OTAA Class A sensor by default. Each LHT65N-PIR is shipped with a worldwide unique set of OTAA keys. To use LHT65N-PIR in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65N-PIR.
86
87 If LHT65N-PIR is within the coverage of this LoRaWAN network. LHT65N-PIR can join the LoRaWAN network automatically. After successfully joining, LHT65N-PIR will start to measure environment temperature, humidity & people activity, and start to transmit sensor data to the LoRaWAN server. The default period for each uplink is 20 minutes.
88
89
90 == 2.2 How to Activate LHT65N-PIR? ==
91
92 The LHT65N-PIR has two working modes:
93
94 * (% style="color:blue" %)**Deep Sleep Mode**(%%): LHT65N-PIR doesn't have any LoRaWAN activation. This mode is used for storage and shipping to save battery life.
95
96 * (% style="color:blue" %)**Working Mode**(%%):  In this mode, LHT65N-PIR works as LoRaWAN Sensor mode to Join LoRaWAN network and send out the sensor data to the server. Between each sampling/tx/rx periodically, LHT65N-PIR will be in STOP mode (IDLE mode), in STOP mode, the PIR sensor is still working to detect people activity in low power consumption.
97
98 The LHT65N-PIR is set in deep sleep mode by default; The ACT button on the front is to switch to different modes:

107
108
109 (% class="wikigeneratedid" %)
110 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.

116
117 Assume the LPS8v2 is already set to connect to [[TTN V3 network>>url:https://eu1.cloud.thethings.network||_mstvisible="2"]], So it provides network coverage for LHT65N-PIR. Next we need to add the LHT65N-PIR device in TTN V3:
118
119
120 === 2.3.1 Step 1: Create Device n TTN ===
121
122
123 Create a device in TTN V3 with the OTAA keys from LHT65N-PIR.
124
125 Each LHT65N-PIR is shipped with a sticker with its device EUI, APP Key and APP EUI as below:
126
127 [[image:image-20220617150003-1.jpeg||_mstalt="5426434"]]
128
129 User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screenshot:
130
131 Add APP EUI in the application.

151
152
153 === 2.3.2 Step 2: Activate LHT65N-PIR by pressing the ACT button for more than 5 seconds. ===
154
155 Use ACT button to activate LHT65N-PIR 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.

159 == 2.4 Uplink Payload~-~-Device Status, (Fport~=5) ==
160
161 Users can use the downlink command(**0x26 01**) to ask LHT65N-PIR to send device configure detail, include device configure status. LHT65N-PIR will uplink a payload via FPort=5 to server.
162
