Once you have everything set up, you are ready to conduct your experiments. Format the scatter graph to what you require.Select all 13 columns D to P for plotting.Readings are roughly every 4 seconds so create a sequence as shown.Insert a column next after column “C” to specify the time in seconds.Select column “C”, which contains “TOUCH”, “FDAT” and “DIFF”, and select Filter.Delete the first row that contains “TOUCH:” or “DIFF:” in the column “C”.Set the date format to “YMD” and then click “Finish”.Select “Delimited” and in the next screen check “Tab” and “Space”.
In order to plot the data with Excel, first open Excel and then within Excel, open the CoolTerm text file.When finished capturing data, navigate back to Connection, Capture to text/binary file, then Stop.To capture data in a txt file, go to the Connection menu, then Capture to Text/Binary file and then click Start.CoolTerm will now display the sensor’s readings.Click OK to save and then click Connect to start.If you need timestamps, open the Receive Options on the left hand pane and under Capture File Options, tick “Add timestamps to captured data”.Set the Baudrate to “115200”, Data Bits to “8”, Parity to “None” and Stop Bits to “1”.Select the port where the LAIIER board is plugged in, the name should be similar to “usbmodem14301”.

The Micro USB port outputs serial data of the sensor's measurements which is explained in the instructions. You may notice an Arduino footprint has been used on the board which will allow for further capabilities in the future. It includes a microcontroller chip, FFC connector, power switch, and a Micro USB output port. This PCB has been manufactured specifically for Liquid Leak Sensors and its future updates. Within the kit, you will find the Bravo Board PCB. As this sensor detects the change in resistance, it has been tested to be optimal for conductive liquids (i.e. The distance between these individual tracks determines the sensor’s sensitivity so narrower gaps can detect smaller droplets and vice versa.
This signal can be detected and filtered by the microcontroller on the Bravo Board. Within each segment, there are several pairs of conductive tracks and when a liquid bridges these tracks, there is a change in electrical resistance. Conductive ink is printed into a unique pattern that divides the print into twelve sensing segments allowing the liquid to be detected by a specific part of the sensor. Our Liquid Leak Sensors are based on resistive sensing.
