General Operating Modes of SCD
The operation modes are described in this chapter. For information about how to configure the SCD or how to
retrieve data from it, please refer to chapter 5 Installation and Start to Use.
6.1
General Behavior
The user can activate/deactivate each sensor in SCD to get data. Additionally, for logging the data, user can
specify different sampling rates for each sensor. On the other hand, SCD uses an optimal (fixed) sampling rate
to stream the data to the app to be visualized.
6.2
Resetting the SCD
If there are problems with the SCD, a restart of the SCD may be necessary.
In order to reset the SCD, please do the following steps:
Press the button on the SCD for at least 10 seconds.
When the button released after 10 seconds, the LED shows a short red light.
6.3
Streaming via Bluetooth Low Energy (BLE)
SCD is a Bluetooth Low Energy (BLE) device. This means that another BLE device may detect the SCD when
scanning for devices and is able to initiate a connection. By using BLE, it is possible to configure the SCD and
continuously receive measurement data. The data can be visualized in the app or consumed in a gateway. If the
user wants to integrate the SCD into his/her gateway, the required document e.g. the SCD BLE Communication
Protocol is publicly available in the website to download.
6.4
Logging Data into the Local Memory
SCD can be configured to log raw-data into its local memory. This data can be downloaded afterwards by the
smartphone app or by a gateway. Logging into the local memory is the right way to get accurate raw-data for
data analysis. SCD is able to log data in the memory, and at the same time, stream the data via BLE.
When the user starts logging in the app, the SCD continues to log data until the local memory is full or logging is
stopped by the user. The time until the memory is full depends on the SCD settings. Please see below some
examples.
Examples:
Accelerometer @6.4kHz (1 axis) will fill the memory in 60 seconds
Accelerometer @3.2kHz (3 axis) will fill the memory in 40 seconds
Accelerometer @1.6 kHz (3 axis) will fill the memory in 80 seconds
Temperature alone will fill the memory in 21 days
INFO: All stored values are lost in this process. Only the name of the SCD stays unchanged.
