Application of Micro Electro-Mechanical Sensors (MEMS) Devices with Wifi Connectivity and Cloud Data Solution for Industrial Noise and Vibration Measurements

Abstract

Abstract This paper introduces the application of Microelectromechanical Systems (MEMS) for industrial noise and vibration measurements. Sound measurement was done using a compact sound level meter with type 1 Micro-Electro-Mechanical Systems (MEMS) microphone while the vibration measurement used a compact vibration measuring device with 3-axial accelerometer, which is also a MEMS type sensor. The MEMS Sensors being used in both measuring devices provide advantages in terms of features and specifications such as weight reduction, compact in size and economically affordable for various applications. Besides MEMS Sensors, the devices are equipped with wireless connectivity to a local server via a WIFI router. This eliminates the usage of wired connection in data handling. Furthermore, Cloud connectivity is an add-on feature to the wireless capabilities of both devices. Using the Cloud features enable threshold alert alarm, data monitoring and collection to be done regardless of time and location of devices, provided that the internet connectivity is available to the user and the devices.
