testing the project

after finish up the project, it's time to test the functionality the system of the project. Alhamdulillah, the project  running as expected  before. To do some backup while presentation day, I added new input and combine the sensor input and switch input by using OR gate which means if either one of the input running, the process will continue run usually. What I means here, in the hall, the students are not allowed to used the firing material because it can activate the alarm system in the hall, so that the switch function to give input for the system without doing burning process so supply smoke to the MQ2 sensor.

figure above is the image of backup input switch on the control system board

the figure shows the AC fan running out while the input switch pressed ( or smoke sensor send the output) and at the same time, water pump 1 and water pump 2 will pumped the water to supply source for water mist system. Three system are work together while get the input signal.

the three system are work about 20m=20seconds delay time.. after that the green bulb will blow up to shows the smoke are clean about 90% because last stage sensor did not give any output, which means the smoke on the last stage cannot be detected and it means the smoke in clean situation.

from the estimation, the result shows like below:-

that the result that i can get from the estimation of my "Automatic smoke absorber machine".
