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:

127 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:
128
129
130 === 2.3.1 Step 1: Create Device n TTN ===
131
132
133 Create a device in TTN V3 with the OTAA keys from LHT65N-PIR.
134
135 Each LHT65N-PIR is shipped with a sticker with its device EUI, APP Key and APP EUI as below:
136
137 [[image:image-20230426083533-1.png]]
138
139
140 User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screenshot:
141
142 Add APP EUI in the application.

164
165 === 2.3.2 Step 2: Activate LHT65N-PIR by pressing the ACT button for more than 5 seconds. ===
166
167
168 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.

412 == 2.7 LED Indicator ==
413
414
415 The LHT65N-PIR has a triple color LED which for easy showing different stage .
416
417 While user press ACT button, the LED will work as per LED status with ACT button.
418
419 In a normal working state:
420
421 * For each uplink, the BLUE LED or RED LED will blink once.
422 BLUE LED when external sensor is connected.
423 * RED LED when external sensor is not connected
424 * For each success downlink, the PURPLE LED will blink once
425
426 == 2.8 installation ==
427
428 ~1. Don't install LHT65N-PIR outdoor or place where will get wet.
429
430 2. Towards the PIR probe to the place where need to monitor activity. Below is the detect beam.
431
432 Stable distance is 0~~3m. Some motion might not detected between 3~~5 m.
433
434 [[image:image-20230411135341-1.png||height="450" width="456"]]
435
436 **Notice: PIR can only detect motion activity, not to use to detect static people case.**
437
438 * 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.
439 * 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.
440 * 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.
441 * 4. Between the detection range of PIR Motion detector, there is should be less objects.  Many objects may reduce the sensitive of detection range.
442 * 5. Do not install more than one (2 or above) Wireless PIR in the same detection space (like at the same room).
