Wireless IMU / Description

This app sends the measurements from your phone inertial sensors via UDP as CSV (Comma-Separated Values) to a computer in your network.
This turns your phone into a wireless inertial measurement unit (IMU).

The following sensors are supported:

- Accelerometer
- Gyroscope
- Magnetometer

If your phone has not all these sensors only the available sensor data is transmitted.

Example UDP packet:
890.71558 3 0.076 9.809 0.565 4 -0.559 0.032 -0.134 5 -21.660-36.960-28.140

Timestamp [sec] sensorid x y z sensorid x y z sensorid x y z

Sensor id:
3 - Accelerometer (m/s^2)
4 - Gyroscope (rad/s)
5 - Magnetometer (micro-Tesla uT)

You can run this app in the background.
A warning dialog appears if you are not connected to a WiFi network.

In the example video the stream is directly processed by a MATLAB script for Kalman Filtering. But it's up to you what you do with the data.

With the following Python script you can capture the UDP data stream from your phone:

# -------------------------------------------------------
import socket traceback

host = ''
port = 5555

s = socket.socket(socket.AF_INET socket.SOCK_DGRAM)
s.setsockopt(socket.SOL_SOCKET socket.SO_REUSEADDR 1)
s.setsockopt(socket.SOL_SOCKET socket.SO_BROADCAST 1)
s.bind((host port))

while 1:
try:
message address = s.recvfrom(8192)
print message
except (KeyboardInterrupt SystemExit):
raise
except:
traceback.print_exc()
# -------------------------------------------------------
