1.1	82
3.1	83	== 2.1 How does LHT65N-PIR work? ==
1.1	84
3.1	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.
1.1	86
3.1	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.
1.1	88
	89
3.1	90	== 2.2 How to Activate LHT65N-PIR? ==
1.1	91
4.1	92	The LHT65N-PIR has two working modes:
1.1	93
4.1	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.
3.1	95
4.1	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.
1.1	97
4.1	98	The LHT65N-PIR is set in deep sleep mode by default; The ACT button on the front is to switch to different modes:
