www.wisencn.com Page - 3 - of 12 Wisen Innovation Technical Doc. No.2026 WiSenMeshWAN Vibration Sensor Node - User Manual 1. Product Introduction The WiSenMeshWAN Vibration Sensor Node is one of the key products in our patented WiSenMeshWAN geotechnical safety monitoring system. Working together with the WiSenMeshWAN gateway product, it intelligently delivers real-time vibration, tilt, temperature and humidity data to the information centre. The WiSenMeshWAN Vibration Sensor Node operates using our core technology, i.e., the WiSenMeshWAN Low Power, Intelligent, Wireless Sensor Network protocol, together with its internal high precision MEMS accelerometer and power unit. This product satisfies the three fundamental identities of the system:
A. Network Life Span: to maximise battery life across the mesh network as a whole;
B. Network Data Arrival Rate: to minimise data packet loss;
C. Single Node Environmental Coverage: to maximise radio coverage. Our product has IP68 and is designed to work in a tough environment. It is small in size, reliable in performance, easy for maintenance, has high precision during sampling, and has strong immunity to radio-interference. The node supports three operating modes: time-interval based sampling, event-driven self-triggering, and real-time USB output. Figure 1.

(1) Mesh Antenna
(2) M4 x 16 Lid Screw
(3) Cable Gland Figure 3. Vibration Sensor Node Terminologies. 5. Operation Procedures 5.1System Deployment Notifications 1) Location: The deployment location of a Vibration Sensor Node is usually determined by the required monitoring or inspection location;
2) All the Serial Numbers of a Unit must be recorded against their site references;
3) Before any Vibration Sensor Node is switched on, two tasks will need to be carried out:
A. Ensure the node is properly mounted on the structure under test;
B. A gateway must be deployed, powered on and proven to be working properly. The rules to follow to correctly deploy a WiSenMeshWAN system are: Gateway first, then nearby nodes, then further nodes. 4) During deployment, the Serial Number (SN) of a node and the orientation of the sensors deployed against their site references must be recorded;
5) All the nodes should have their antenna point upwards. 5.2Deployment Procedures 1) Open the box: Take the node out of the package and open its lid;
2) Insert Battery: By default, a node does not contain a D-Cell battery. Therefore the battery needs to be inserted. Notice
: +ve and ve orientation must be correct, otherwise, the internal circuit may be damaged. www.wisencn.com Page - 8 - of 12 Wisen Innovation Technical Doc. No.2026 WiSenMeshWAN Vibration Sensor Node - User Manual 3) Antenna Installation: screw the antenna tightly onto the node;
4) Sensor Installation: Securely attach the node to the structure using appropriate mounting brackets. Ensure good contact for vibration transmission. 5) Power On: Turn the switch on. You should see LEDs flashing, which means the node is on. Then switch off the node to save power if the gateway is off;
6) Tighten the 4 Cap-Hex-Head screws of the lid to secure the enclosure IP rating;
7) To validate the sensor data, please visit Wisen Visualisation Platform for further details. Mode Selection: The node supports three modes:
Mode 1 (Time Interval Based Sampling): Outputs acceleration, velocity, displacement, static tilt at each T. Mode 2 (Event-driven Self-triggering): Outputs acceleration over the biggest 3 vibration events exceeding a threshold. Mode 3 (USB real-time output): Connects to a PC via USB Type-C cable for real-time data streaming. 5.3Mounting Options The Vibration Sensor Node can be deployed with various methods. However, the principle is to make sure it is firmly attached to the installation surface. 6. General Maintenance and Notification 1) Once the Vibration Sensor Node is installed in the field, please minimise any man-made disturbance so that data quality can be maintained;
2) Radio communication will be impaired if the antenna is covered by metal or very moist soil material;
3) Due to the discharge characteristics of the recommended battery, a battery replacement should be carried out when a node reported voltage reaches 2.7V, at which point you have approximately 3 weeks to change the battery;
4) Our product will use all the possible capacity in a battery down to its stop (minimum) voltage, which has been specified in the Features table. When this occurs, our WiSenMeshWAN protocol will send you a warning, then it will enter a deep sleep mode until a new battery is installed;
5) If the data from nodes are showing unexpected results or are not being sent back to the Wisen gateway, then please carry out investigation using the following two stage procedure:
www.wisencn.com Page - 9 - of 12 Wisen Innovation Technical Doc. No.2026 WiSenMeshWAN Vibration Sensor Node - User Manual A. Remote Inspection of historical data, to identify the following:
a) Whether the heart-beat message has been sent back successfully at each time interval;
b) Whether the battery voltage is too low, if yes, please change the battery unit;
c) Whether the signal strength has become significantly weaker than before. If yes, please check the antenna has been screwed on firmly. B. On-site Inspection: If all the above are good, please arrange an on-site inspection to check:
a) Whether a Node has visible external damage;
b) Check the box lid to see if it is firmly tightened;
c) Whether the antenna is bent or damaged and that the node is not blocked by new construction, e.g., hoardings;
d) When possible, check that the signal strength is normal by using a spectrum analyser;
e) Open the lid, to see whether the battery is firmly attached to its holder;
f) Use a multi-meter to measure the battery voltage. If it is below the stop (minimum) voltage, replace the battery. Notices
i. Case One: If any change has been made from the list above, please inspect the data at the remote server;
ii. Case Two: If all the actions from the list above have not cured the problem, please contact Wisen. We will be happy to help. 7. Package and Accessories Standard:

Safety and Warning Warning: Please read the following instructions carefully. 1Operation Safety Before taking any action, please read all the information provided carefully, and keep the guidance documents safe;
Ensure that any procedures and installations are correctly carried out. The communication cable and the case must be grounded;
This product has been designed to meet a certain water-proof level. However, it becomes water vulnerable when the lid is open or if the cable gland has not been sealed properly. 2Electric Safety To install the battery into a holder, please follow the + (positive) and - (negative) signs in any Wisen product. Wrong orientation of a battery could potentially cause unit damage. Notice
: The orientation of battery can vary among products;
When disconnecting the battery, please take special care not to apply excessive force, otherwise the battery holder and the nearby circuitry may be damaged. 3Warning The battery in the product has a relatively high capacity, so please take special care during storage and usage;
This product must not be disassembled under any circumstances, to do so will void the warranty and may leave the product in a dangerous state;
If all the above are not followed, the manufacturer cannot be responsible for any damage and injury caused to the users. 4Caution Danger of explosion if battery is incorrectly replaced. Replace only with the type recommended by the manufacturer;
When disposing of the batteries, please contact your local authorities or dealer and ask for the correct method of disposal. www.wisencn.com Page - 11 - of 12 Wisen Innovation Technical Doc. No.2026 WiSenMeshWAN Vibration Sensor Node - User Manual 9. Contact
