20 == 1.1 What is the LHT65N-VIB LoRaWAN Vibration Sensor? ==
21
22
23 The Dragino LHT65N-VIB (% style="color:blue" %)**LoRaWAN Vibration Sensor**(%%) is designed to (% style="color:blue" %)**detect and measure vibrations, shocks, and accelerations of an object**(%%). By analyzing the object's motion, the LHT65N-VIB can send meaningful data such as alarms, device runtime, vibration counts, and vibration strength to an IoT platform for further analysis.
24
25 It can be used in professional wireless sensor network applications, including (% style="color:blue" %)**equipment status monitoring, water leakage alarms, usage statistics, vibration intensity detection**(%%), and more.
26
27 The LHT65N-VIB (% style="color:blue" %)**supports a datalogging feature**(%%), allowing it to record data when there is no network coverage. Users can retrieve the sensor readings later, ensuring no data is missed.
28
29 The LHT65N-VIB enables users to send data over extremely long distances. It offers ultra-long-range spread spectrum communication and high interference immunity while minimizing current consumption.
30
31 The LHT65N-VIB has a(% style="color:blue" %)** built-in 2400mAh non-rechargeable battery**(%%), which can last up to 3 years*.
32
33 The LHT65N-VIB is fully compatible with the LoRaWAN v1.0.3, Class A mode and can work with a standard LoRaWAN gateway.
34
35 *The actual battery life depends on how frequently data is transmitted. Please refer to the battery analyzer chapter for more details.

80 = 2. Registering LHT65N-VIB with a LoRaWAN Network Server =
81
82
83 **The LHT65N-VIB can be registered with any LoRaWAN network server. In this documentation, we use The Things Stack as an example, but similar settings may apply to other LoRaWAN network servers.**

85
86 == 2.1 How does the LHT65N-VIB work? ==
87
88
89 (((
90 The LHT65N-VIB is configured in LoRaWAN Class A mode by default. Each LHT65N-VIB is shipped with a unique global registration key that supports OTAA (Over-The-Air-Activation). To use the LHT65N-VIB with a LoRaWAN network, you first need to register the device with the network using the provided registration keys for OTAA support.
91
92 The LHT65N-VIB's registration information can be found inside the device package.
93
94 [[image:image-20230426083319-1.png||_mstalt="431106" height="258" width="556"]]
95
96 The registration information includes the following:
97
98 * DevEUI
99 * AppEUI
100 * AppKey
101
102 Once registered, if the LHT65N-VIB is within the coverage area of the LoRaWAN network, it can automatically join the network. After successfully joining, the LHT65N-VIB will begin measuring environmental temperature and humidity and will start transmitting sensor data to the LoRaWAN network server. The default uplink transmission interval is 20 minutes.

118
119 (((
120 * (% style="color:blue" %)**Working mode**(%%): In this mode, the LHT65N-VIB works as a LoRaWAN sensor, joining the LoRaWAN network and sending sensor data to the server. Between each sampling/TX/RX cycle, the LHT65N-VIB enters STOP mode (IDLE mode), where it consumes the same power as in deep sleep mode.
121 )))
122
123 The LHT65N-VIB is set in deep sleep mode by default. The **ACT** button on the front can be used to switch between different modes. See the image below:

619 == 2.5 Integrating with IoT platforms ==
620
621
622 The LHT65N-VIB sensor data can be integrated with other IoT platforms for better visualizing and analyzing the data. In this section, we will show you how to integrate sensor data from The Things Stack with some popular IoT platforms.
623
624
625 === 2.5.1 Integrate and show data on ThingsEye ===
626
627
628 The Things Stack application supports integration with ThingsEye.io. Once integrated, ThingsEye.io acts as an MQTT client for The Things Stack MQTT broker, allowing it to subscribe to upstream traffic and publish downlink traffic.
629
630
631 ==== 2.5.1.1 Configuring The Things Stack ====
632
633 We use The Things Stack Sandbox in this example:
634
635 * In **The Things Stack Sandbox**, go to the **Application **for the LHT65N-VIB you added.
636 * Select **MQTT** under **Integrations** in the left menu.
637 * In the **Connection information **section, under **Connection credentials**, The Things Stack displays an auto-generated **username**. You can use it or provide a new one.
638 * Click the **Generate new API key** button to generate a password. You can view it by clicking on the **visibility toggle/eye** icon. The API key works as the password.
639

1693 Some clients need to calibrate the sensor values in a calibration lab. In such cases, reading the data without a LoRaWAN network is more convenient. To achieve this, you can use a USB Type-C breakout board to expose the UART pins while still keeping the probe connected. See below for details. For the pinout, please refer to the FAQ on H[[ow to connect LHT65-N via UART interface>>||anchor="H6.1HowtoconnecttoLHT65NUARTinterface3F"]].

1753
1754 This means that when the water faucet remains on, a vibration lasting more than 120 seconds will trigger an alarm. When the vibration stops for more than 5 seconds, the vibration count will increase by 1.
1755
1756 * The data begins to rise after 8 o'clock, indicating that the wash basin sensor is working normally.
1757 * During lunch time, from 12 noon to 1:30 PM, the data temporarily levels off but returns to normal operation after.
1758 * At 6 PM, after work hours, the data flattens out, with only a small amount recorded, caused by employees working overtime and using the wash basin.

1761
1762
1763 * Number of wash basin alarms: 14 times
1764 * The rest period is concentrated around 12 o'clock, as people wash their hands during the lunch break.
1765 * The longer duration at 6 o'clock is due to someone needing to turn on the water to clean the toilet.

1770 **Sink installation example:**
1771 Fix the probe to the water inlet pipe of the sink using a cable tie. Since the vibration in the middle is not as noticeable, and the water outlet on the right is larger than the one on the left, resulting in a larger vibration amplitude, the probe should be installed at the middle of the left water inlet pipe. This way, vibrations can be detected on both sides of the water pipe.

1781 This means that if the vibration exceeds 120 seconds, an alarm message will be issued. When the vibration stops for more than 5 seconds, the number of vibrations will increase by 1.
1782 When the toilet vibrates for only 100 seconds each time it is flushed, any vibration exceeding 120 seconds would indicate an abnormal situation.
1783
1784 * The data starts to rise after 8 o'clock, indicating that the toilet sensor is working normally.
1785 * The data remains flat with no abnormalities during the lunch break from 12:00 PM to 1:30 PM.
1786 * The data stops rising at 6:00 PM when work is over.

1796 **Toilet installation example:**
1797 Fix the probe to the water inlet pipe of the toilet with a wire tie. When the toilet is used, it will pump water, and the LHT65N-VIB will start detecting vibrations in the water pipe. **Note:** LHT65N-VIB should not be immersed in water. If necessary, ensure it is waterproofed.

1805 Set AT+VIBMOD=4,1,10 to collect a set of XYZ vibration data every ten seconds.
1806
1807 By analyzing the data collected in the graph, we can observe that the vibration amplitude of the machine varies significantly under different working conditions. This monitoring method not only helps to determine in real time whether the machine is operating normally but also allows for the early detection of any abnormal changes in vibration frequency. This, in turn, helps to effectively prevent potential failures and ensures the safe and stable operation of the equipment.
