Commands for using built-in sensors

B1:Temperature
B2:Air Pressure
B3:Light Intensity
B4:Proximity
B5:GPS
B6:Compass & H-field
B7:Angular Velocity
B8:Orientation/Inclination
B9:Acceleration

Slot# refers to the default socket number to plug in the external sensor. The number may be re-allocated by the user.

Connection to mobile logger by Bluetooth

  1. Click the Search BT Devices button to enable your Bluetooth device and scan for your logger.
  2. After a while (~1 min), you should choose the Bluebooth for your device and note its name such as MLGXY (e.g. MLG03) or (SESXY, e.g. SES27 for older version).
  3. Input PIN = XYXY (e.g. 0303) to connect via Bluetooth.

Even without Bluetooth connection to any mobile logger, you may click the right top menu to (a) preview files (including log records *.log, graph data *.txt, graphs and photos *.jpg), (b) plot graphs, (c) draw Google maps (if GPS data collected) for existing log records and (d) use built-in sensors of your mobile device to collect data.

You can also connect to the mobile logger by Wi-Fi (if module available) or USB cable.
