19
20 The Dragino (% style="color:blue" %)**LHT65S-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**(%%)**.** LHT65S-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.
21
22 The LHT65S-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.

73
74 == 2.1 How does LHT65S-PIR work? ==
75
76
77 LHT65S-PIR is configured as LoRaWAN OTAA Class A sensor by default. Each LHT65S-PIR is shipped with a worldwide unique set of OTAA keys. To use LHT65S-PIR in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65S-PIR.
78
79 If LHT65S-PIR is within the coverage of this LoRaWAN network. LHT65S-PIR can join the LoRaWAN network automatically. After successfully joining, LHT65S-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.
80
81
82 == 2.2 How to Activate LHT65S-PIR? ==
83
84
85 The LHT65S-PIR has two working modes:
86
87 * (% style="color:blue" %)**Deep Sleep Mode**(%%): LHT65S-PIR doesn't have any LoRaWAN activation. This mode is used for storage and shipping to save battery life.
88
89 * (% style="color:blue" %)**Working Mode**(%%):  In this mode, LHT65S-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, LHT65S-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.
90
91 The LHT65S-PIR is set in deep sleep mode by default; The ACT button on the front is to switch to different modes:

118 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 LHT65S-PIR. Next we need to add the LHT65S-PIR device in TTN V3:

434
435 Stable distance is 0~~3m. Some motion might not detected between 3~~5 m.

438
439
440 (% style="color:red" %)**Notice: PIR can only detect motion activity, not to use to detect static people case.**
441
442 * 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.
443
444 * 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.
445
446 * 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.
447
448 * 4. Between the detection range of PIR Motion detector, there is should be less objects.  Many objects may reduce the sensitive of detection range.
449
450 * 5. Do not install more than one (2 or above) Wireless PIR in the same detection space (like at the same room).
