20
21 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.
22
23 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.

74
75 == 2.1 How does LHT65N-PIR work? ==
76
77
78 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.
79
80 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.
81
82
83 == 2.2 How to Activate LHT65N-PIR? ==
84
85
86 The LHT65N-PIR has two working modes:
87
88 * (% 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.
89
90 * (% 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.
91
92 The LHT65N-PIR is set in deep sleep mode by default; The ACT button on the front is to switch to different modes:

124 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:
125
126
127 === 2.3.1 Step 1: Create Device n TTN ===
128
129
130 Create a device in TTN V3 with the OTAA keys from LHT65N-PIR.

626
627 2. Towards the PIR probe to the place where need to monitor activity. Below is the detect beam.
628
629 Stable distance is 0~~3m. Some motion might not detected between 3~~5 m.

632
633
634 (% style="color:red" %)**Notice: PIR can only detect motion activity, not to use to detect static people case.**
635
636 * 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.
637
638 * 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.
639
640 * 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.
641
642 * 4. Between the detection range of PIR Motion detector, there is should be less objects.  Many objects may reduce the sensitive of detection range.
643
644 * 5. Do not install more than one (2 or above) Wireless PIR in the same detection space (like at the same room).

849 In PC, User needs to set serial tool(such as [[**putty**>>https://www.chiark.greenend.org.uk/~~sgtatham/putty/latest.html]], SecureCRT) baud rate to (% style="color:green" %)**9600** (%%)to access to access serial console for LHT65N-PIR. The AT commands are disable by default and need to enter password (default:(% style="color:green" %)**123456**(% style="color:red" %))(%%) to active it. Timeout to input AT Command is 5 min, after 5-minute, user need to input password again. User can use AT+DISAT command to disable AT command before timeout.
