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. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, building automation, and so on.

81
82 == 2.1 How does LHT65N-PIR work? ==
83
84 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.
85
86 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.
87
88
89 == 2.2 How to Activate LHT65N-PIR? ==
90
91 The LHT65N-PIR has two working modes:
92
93 * (% 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.
94
95 * (% 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.
96
97 The LHT65N-PIR is set in deep sleep mode by default; The ACT button on the front is to switch to different modes:

115
116 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:
117
118
119 === 2.3.1 Step 1: Create Device n TTN ===
120
121
122 Create a device in TTN V3 with the OTAA keys from LHT65N-PIR.
123
124 Each LHT65N-PIR is shipped with a sticker with its device EUI, APP Key and APP EUI as below:
125
126 [[image:image-20220617150003-1.jpeg||_mstalt="5426434"]]
127
128 User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screenshot:

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

391 (% style="color:blue" %)**Method 2: **(%%)Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], LHT65N-E5 will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N-E5 will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
392
393
394 (% style="color:red" %)**Note for method 2:**
395
396 * a) LHT65N-E5 will do an ACK check for data records sending to make sure every data arrive server.
397 * b) LHT65N-E5 will send data in **CONFIRMED Mode** when PNACKMD=1, but LHT65N-E5 won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if LHT65N-E5 gets a ACK, LHT65N-E5 will consider there is a network connection and resend all NONE-ACK Message.
