LABDA Accelerometers

A package designed to process data from movement sensors – accelerometers.

• Auto-calibration
• Non-wear detection
• Metrics: Counts, ENMO
• Python

See documentation for more details.

Installation

Install using pip install labda-accelerometers.

A Simple Example

import pandas as pd
from labda_accelerometers import Metrics, AutoCalibrate, WearDetection

df = AutoCalibrate().calibrate(df)
print(df)
#>                                         acc_x     acc_y     acc_z

epoch = 1 # In seconds

acc_wear = WearDetection(epoch=epoch).from_acceleration(df)
metrics = Metrics(epoch=epoch)

enmo = metrics.enmo(df)
counts = metrics.counts(df)

results = pd.concat([acc_wear, enmo, counts], axis=1)
print(results)
