Logtta Accel is an application that can easily measure and analyze vibration.
There are a method of using the acceleration sensor of the Android main body and a method of using the optional wireless acceleration sensor.
■ The following functions can be used when using the Android's accelerometer.
-Effective for measuring in a short time, such as checking the presence or absence of abnormalities while viewing the measured waveform in real time. Since the waveform can be recorded as a CSV file, you can check the waveform slowly later.
・ In addition to the function to zoom in / out by pinch operation, scroll by swipe, and playback of acceleration data recorded in CSV file, you can also observe acceleration spectrum by FFT and Lissajous figure of 3 planes at the same time.
■ In addition to the above, the following functions can be used when using an optional wireless accelerometer.
-Acceleration can be measured wirelessly by attaching it to the measurement target device anytime, anywhere.
・ Logs can be saved in the sensor for long-term measurements. The log data records the effective and maximum acceleration values, temperature and humidity.
-Real-time alert judgment according to acceleration and temperature / humidity is possible by using beacon mode.
-Clouds such as IFTTT and IBM Watson IoT Platform can be used by using beacon mode.
Main performance specifications of the wireless accelerometer.
・ Range: ± 19.6m / s2 (± 2G), ± 39.2m / s2 (± 4G), ± 78.5m / s2 (± 8G)
・ Measurement axis x / y / z / x-y / x-z / y-z / xyz
・ Sampling frequency 50/100/200/400 / 800Hz
・ Resolution 8 / 12Bit
・ Measurement interval: 1 to 600 seconds
・ High-pass filter for acceleration displacement (time differential value) measurement
