1. Experimental Testing on Sound Sensor Module
π 29 April 2019
β 10.00 am - 12.00 pm
π¬ Lab 209, UniKL BMI
π Experimental testing was conducted at Lab 209. The purpose of this experimental testing is to test the functionality of the sound sensor module which is FC-04 sound sensor module. There were two experiments conducted related to the sound alarm of medical equipment. A Phillips SureSigns VM6 Patient Monitor is used as the source of sound alarm.
π Before conducting the experiment, the circuit of the sound sensor module is constructed on the breadboard. FC-04 sound sensor module has three pins; VCC, GND and VOut. VCC pin is connected to the 5V of power supply, GND pin is connected to the ground and Vout pin is connected to the oscilloscope probe to observe the output waveform. The sound sensor is pointed as close as possible to the source of sound alarm on the patient monitor to ensure the optimum capture of sound alarm.
π Two conditions of the patient monitor are observed. First, the sound alarm during SPO2 non-pulsatile and second, the sound alarm during ECG probe unattached. SPO2 non-pulsatile is done by the sudden removal of the finger from the SPO2 probe after normal condition. When SPO2 probe is not detecting any signal, the sound alarm is triggered. This sound alarm is captured by the sound sensor and the waveform's pattern is observed on the oscilloscope and the parameters are recorded. ECG probe unattached condition is done by detaching the ECG probe from its place at the left side of the patient monitor. This condition triggered the sound alarm and the sound sensor captured the sound. The waveform is observed on the oscilloscope and the values are recorded.
π From both experiments, it can be concluded that FC-04 sound sensor module is in a fit condition and functioning well.

2. Updating FYP1 Slide Presentation
π FYP1 proposal defense day is around the corner. which is on 8th May 2019 (Wednesday). Due to the experimental testing that has been done on 29th April 2019, all of the preliminary results are inserted in the slide presentation. FYP1 slide presentation consists of an introduction, problem statements, objectives, scope of work, methodology, preliminary result, Gantt chart, expected result and conclusion. Literature review about journals, articles and sensors are also inserted in the slide presentation. Two problem statements which parallel with two objectives are shown for the proof of generating the idea of this project. This project is significant as it is proven based on the survey session conducted at Radibems, UniKL BMI and Radibems, Selayang Hospital.
