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:

106 == 2.3 Example to join LoRaWAN network ==
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.

115
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.

143
144 (% style="color:red" %)**Note: LHT65N-PIR use same payload decoder as LHT65.**
145
146
147 Input APP EUI,  APP KEY and DEV EUI:

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   ( Fport~=2) ==
160
161 The uplink payload includes totally 11 bytes. Uplink packets use FPORT=2 and (% style="color:#4f81bd" %)**every 20 minutes**(%%) send one uplink by default.
162
163 After each uplink, the (% style="color:blue" %)**BLUE LED**(%%) will blink once.

197 * The First 6 bytes: has fix meanings for every LHT65N-PIR.
198 * The 7th byte (EXT #): defines the external sensor model. It can be 0x0A for LHT65N-PIR
199 * The 8^^th^^ byte: Alarm Bit (if this uplink is from periodically or movement)
200 * The 9^^th^^ ~~ 11^^st^^  byte: Movement Detect Count.

202 === 2.4.1 Decoder in TTN V3 ===
203
204
205 When the uplink payload arrives TTNv3, it shows HEX format and not friendly to read. We can add LHT65N-PIR decoder in TTNv3 for friendly reading.
