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.

353 Datacake IoT platform provides a human-friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:
354
355 (% style="color:blue" %)**Step 1**(%%): Be sure that your device is programmed and properly connected to the LoRaWAN network.
356
357 (% style="color:blue" %)**Step 2**(%%): Configure your Application to forward data to Datacake you will need to add integration. Go to TTN V3 Console ~-~-> Applications ~-~-> Integrations ~-~-> Add Integrations.

381 == 2.7 LED Indicator ==
382
383
384 The LHT65N-PIR has a triple color LED which for easy showing different stage .
385
386 While user press ACT button, the LED will work as per LED status with ACT button.
387
388 In a normal working state:
389
390 * For each uplink, the BLUE LED or RED LED will blink once.
391 BLUE LED when external sensor is connected.
392 * RED LED when external sensor is not connected
393 * For each success downlink, the PURPLE LED will blink once
394
395 == 2.8 installation ==
396
397 ~1. Don't install LHT65N-PIR outdoor or place where will get wet.
398
399 2. Towards the PIR probe to the place where need to monitor activity. Below is the detect beam.
400
401 Stable distance is 0~~3m. Some motion might not detected between 3~~5 m.
402
403 [[image:image-20230411135341-1.png||height="450" width="456"]]
404
405 **Notice: PIR can only detect motion activity, not to use to detect static people case.**
406
407 * 1. PIR Motion Detector should not be installed near the Air conditioner places where with cold wind or hot wind flow, because PIR motion detector is sensitive with the temperature changes of the environment. Environment changes quickly will cause a false alarm.
408 * 2. PIR should not be installed facing the glass window, facing glass window will be interfered by the outside sunlight and moving objects (people or vehicle). The infrared energy can penetrate the glass window.
409 * 3. PIR should not be installed facing the moving objects or background changing objects, movement object will cause airflow change, it may cause false alarm.
410 * 4. Between the detection range of PIR Motion detector, there is should be less objects.  Many objects may reduce the sensitive of detection range.
411 * 5. Do not install more than one (2 or above) Wireless PIR in the same detection space (like at the same room).

460
461
462 === 4.3.1 Set Transmit Interval Time ===
463
464
465 Feature: Change LoRaWAN End Node Transmit Interval.
466

472
473 (% style="color:#4f81bd" %)**Downlink Payload: 0x01**
474
475 Format: Command Code (0x01) followed by 3 bytes time value.
476
477 If the downlink payload=0100003C, it means set the END Node's Transmit Interval to 0x00003C=60(S), while type code is 01.
478
479 * **Example 1**: Downlink Payload: 0100001E  ~/~/ Set Transmit Interval (TDC) = 30 seconds
480
481 * **Example 2**: Downlink Payload: 0100003C  ~/~/ Set Transmit Interval (TDC) = 60 seconds
482
483 === 4.3.2 Get Device Status ===
484
485 Send a LoRaWAN downlink to ask device send Alarm settings.
486
487 * (% style="color:#4f81bd" %)**Downlink Payload**(%%)**:  **0x26 01

516 * 0xA205: Set external sensor type to E5
517
518 === 4.3.4 Set to sleep mode ===
519
520
521 Feature: Set device to sleep mode
522
523 * **AT+Sleep=0**  : Normal working mode, device will sleep and use lower power when there is no LoRa message
524 * **AT+Sleep=1** :  Device is in deep sleep mode, no LoRa activation happen, used for storage or shipping.
525
526 (% style="color:#4f81bd" %)**AT Command: AT+SLEEP**

532
533 * There is no downlink command to set to Sleep mode.
534
535 === 4.3.5 Set UOA (Uplink on Activity) ===
536
537 Feature: Enable / Disable Uplink on Activity
538
539 * **AT+UOA=0**  : Disable UoA
540 * **AT+UOA=1,2** :  Enable UoA , Calm Down Time: 2 minutes. If device already send a uplink on activity, it will not send another uplink on activiy in 2 minutes, even detect activity.
541
542 Notice: Calm Down time range is 1 ~~ 65535 minutes. If user set Calm Down time to low value, such as 1 minute, the sensor might send uplink very frequenctly and battery drain fast.
