Activity: Construct the Circuit on Breadboard & Testing.
This week, I started building the circuit on the breadboard. Referring to figure above, it shows the parts of the circuit diagram for this E-mask project. The circuit consists of a NodeMCU ESP8266 Wi-Fi module, a BMP180 barometric pressure sensor and DHT11 temperature and humidity sensor. In this circuit diagram, the BMP180 pressure and DHT11 humidity sensors are connected according to the correct pin on the ESP8266 module. Based on the diagram above, this is a final implementation for the circuit diagram that has been made for the construction of the prototype throughout this semester.
It can be concluded that the above activity conducted experiments in the circuit. However, the created circuit cannot operate effectively due to the lack of an appropriate cover to measure the pressure and air exhaled. While conducting this experiment, I only used the box as a cover to measure the required parameters because at that time the mask I ordered had not yet reached Malaysia. Overall, the experiment's testing went well, and all components worked well. This concludes the 7th week's activity, and I will try to resolve this issue as soon as possible.
