Vibration sensor

Vibration sensor: The heart of vibration monitoring system

Vibrations are the basis for assessing machine conditions. Condition monitoring essentially comprises the measurement and recording of overall vibration values and operating parameters. It provides information and allows the diagnosis of the general machine condition or very specific ‘disorders’ of the machine.

SZ1 has brought up a new smart vibration monitoring system with MEMS and IoT technologies. Breakthroughs in MEMS technology make sensors much smaller and affordable. Nowadays with same budget, more sensors could be placed on machine components to precisely localize the vibrating source. While the IoT technology provides wireless connectivity so that experts could gain near-real-time visibility into machine conditions without traveling to locations. WiiMine incorporates 3-axial accelerometer, temperature sensor, wireless connectivity and battery into one, easy-to-use product. Its measurement
range (up to 16 g acceleration), sampling rates (up to 1.6 kHz), long battery life (1 year typical), and small, portable model make it ideal for many vibration measurement and monitoring applications.

RMS algorithm simplifies the vibration measurement

WiiMine supports two mounting methods: adhesive mounting and magnet mounting. Adhesive mounting is used with industrial strength double-sided tape for dielectric surface targets, while magnet mounting is used for metal surface targets. Its rugged enclosure assures WiiMine of accurate vibration data acquisition.

WiiMine performs RMS (root mean squared) averaging for vibration measurement. Because acceleration signals are extremely fast by nature, they require high speed sampling and computationally intensive processing. The onboard RMS algorithm provides a slow moving output so that it can be easily measured by a low speed system, greatly simplifying vibration monitoring and measurement works.

Project Goal Recognition

We understand each customer has their own unique knowledge about industrial smart electronics solution, they may face different challenges, thus have different project requirements with different expectation.

Due to the above, the starting point of our job is to recognize the actual project target, helping our customers address the multiple aspects of the whole project, from installation, user experience to maintenance.


Our product team together with skilled engineers, project managers and customer success executives would engage directly with customer’s cross-functional teams, to obtain the full view of client’s challenge as well as the possible untapped pain, while presenting clients the existing solutions & case studies , thus clients could make better decisions about what they should buy.

Research & Design

We are able to develop the customized hardware and software precisely as per clients confirmed requirements.


We would quickly develop a concept-of-approval prototype to realize what clients need, in order to validate the requirements

Test & Trial

We would implement comprehensive testing via trial production, ensuring zero risk of mass-production failure.

Mass Production & Launch

Mass productions come as carefully planned, informed of our customers, with daily logging data shared so that shipment schedule could be reassured.
