 PSLab Android app now contains sensor instruments like LuxMeter, Accelerometer, Barometer, which can record data from different sensors. Let me demonstrate it by using the LuxMeter. LuxMeter is the instrument which can measure the intensity of the light by using the light sensor. Here the LuxMeter is using the sensor built in this Android smartphone, but it can also log data from external sensors like BH1750 or TSL2561 by connecting them to the smartphone using the PSLab hardware device. To start recording, click on the record button on the top right corner. Here the recording of the data has been started. To stop the recording, click on the stop button. Now the recording has been stopped and the log data is stored in the database integrated with the app. For viewing that data, click on the overflow menu and then click on the show log data. This will open an activity which shows the record of every time we have recorded the data. The latest one is on the top, so click on it and we can see the same graph with the data that we have recorded along with the time of recording and the location from where the data has been recorded. We can also export this data into CSV format by clicking on the button at the top right corner. As you can see the data has been recorded and saved to the CSV format. For viewing that data, we will open our default file manager. Here we will open our PSLab folder and now we will open our lux meter and it will show the list of every time CSV file has been generated. So we will click on our latest one. Here we can see the data in form of CSV format. Here it is showing time elapsed, lux meter, along with external information like date of recording, start time, end time, latitude and longitude, time zone and along with device information like device model, brand or android SDK. Thank you.
