Analyse_pH_Express targets all cautious parents who wish to integrate a quick easy medical checkup into a daily ordinary activity. The object, being a children’s potty chair for urinating. However it is no ordinary object! The Analyse_pH_Express monitors your children’s urine’s pH level and offer a medical opinion by comparing it to the expected ordinary healthy level.

Let’s imagine an example of what could happen: parent takes the child to the toilets and the child urinates in the object. Then, the parent empties the object in the adult WC and cleans it with soapy water like any other potty.

The pH is measured instantly and sent to the medical service which output the following: Date/Time/pH/Result. The result could either be OK if the measured value is considered healthy and could also be NOT OK if an abnormal pH was detected. This could offer also a daily review of the daily/weekly use of WC.

This healthy value highly depends on the time of the day. For example:

• 6.8 up to 7.2 Before Breakfast (6h – 10h)
• 4.6 up to 6.8 Before Lunch/After Breakfast (10h – 12h)
• 6.8 up to 7.2 Before Dinner/After Lunch (12h – 20h)
• 4.6 up to 6.8 during the night (20h – 6h)

NONE - Object was not delivered since we are in Egypt. However, we offered him a Description of Work which contains all required details (in French)

We also sent him a sketch done on SketchUp

A pH sensor located beneath the toilet potty chair is connected to a pH/ORP adapter which returns a numerical value of the pH when it varies. The system takes this measure and processes it through an equation to get an understandable measure of pH (on a scale of 0-14). Afterwards, these measures are sent through the UPnP network and saved on the device.

The high added value service consists of a medical service that receives the pH data sent from our object. The service compares the measured pH with the standard healthy pH value according to the current time. Finally, the service logs this data with the current date/time, pH measured value and the analysis result.

• Embedded Container
• Remote Container

• Embedded Bean DLL
• Embedded Bean Source Code

• Remote Bean DLL
• Remote Bean Source Code

• Make sure SharpDevelop (as well as WComp add-on), Phidget Control Pannel, WinSCP, PuTTY and Device Spy are all installed
• Copy all beans (DLL files) into the folder Beans inside the folder where SharpDevelop is installed
• Power on Phidgets and connect it to the Ethernet wire of the PC
• Configure WiFi connection with the help of Phidget Control Pannel then unplug Ethernet Connection (this won’t be needed anymore)
• Open WinSCP and connect to the Phidget by using the IP address and the appropriate username and password. (File protocol: SCP)
• Copy all .wcc and .dll files on the phidget
• Open session in PuTTY then type the appropriate password
• Launch the service : mono Container.exe –r ../Beans –l Analyse_pH_Express_SBC.wcc –n Analyse_pH_Express
• You can now see Analyse_pH_Express in Device Spy with the 2 probes (Threshold & pH sensor values)

• Open Device Spy and copy the Device URL
• Open SharpDevelop and create a new C# Container
• Import Analyse_pH_Express_PC.wcc
• Modify the UPnP Device URL with the copied with one (should become green now)
• Subscribe to Events if you wish to view pH Values through Device Spy
• Open the generated XML Log named “Analyse_pH_Express_Report.xml” found in the folder where SharpDevelop is installed

We can't really offer any positive/negative feedback since we were in another country (in Egypt). The only interaction we had was when we were asked to deliver a Description of Work. Then we got a positive feedback from him indicating that the document contains all required information and the object could be manufactured without any problems.

• User's Temperature Detection could also be interesting to analyse for medical purposes.
• Room's Temperature Detection could also be used for activating a seat warmer mechanism.
• Room's Light Detection could also be added for activating light glowing figures on the object to improve user's vision.

• Adding an internal Log that guarantees persistence
• Adding Temperature/Light sensors
• Adding Vibration sensor to enhance the detection of usage

• Using Google Calendar for detecting the holidays which influence the food/drinks consumed by the user. Therefore, it could affect the urine's pH.
• Comparing csv logs with current xml ones to determine which is most suitable.

• A graph that illustrates the user's pH evolution during the day/week/month.
