Page 5: Introduction
Introduction The WT901BLE BLE5.0 is a multi-sensor device detecting acceleration, angular velocity, angle as well as magnetic filed. The small outline makes it perfectly suitable for industrial retrofit applications such as condition monitoring and predictive maintenance. Configuring the device enables the customer to address a broad variety of use cases by interpreting the sensor data by smart algorithms. -

Page 25: Bandwidth
1. The higher rate of bandwidth setting will lead to higher fluctuation in data waveform. Conversely, the lower rate of bandwidth, data will become more fluent. For example: Bandwidth as 50Hz, Output rate as 5Hz. The waveform is very steady. WT901BLE BLE5.0 | manual v0707 | http://wiki.wit-motion.com/english - 25 -... - Page 26 For example, if the bandwidth setting is 20Hz, retrieval rate as 50Hz, there will be 5 repeating data. If you prefer there is no repeating data, it is required to increase the bandwidth more than 50Hz. WT901BLE BLE5.0 | manual v0707 | http://wiki.wit-motion.com/english - 26 -...
