real hardware before install the system


above is the side view of the hardware before the installation of the control system


image above is the other side views of the hardware(machine) together with the stand of the machine

the real machine are not totally same with the illustration before because the design of the machine must be suit with the size all the part that need to combine to finished.
bottom of the stands will located the tank as the water supply for water mist system. the picture of full machine will be uploaded later.

smoke sensor MQ-2



Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the
target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration
rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of
gas concentration.
MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane
and other combustible steam, it is with low cost and suitable for different application.

Characters of the sensor

*Good sensitivity to Combustible gas in wide range                                                  
* High sensitivity to LPG, Propane and Hydrogen                                      
* Long life and low cost                                          
* Simple drive circuit

Applications

 Domestic gas leakage detector
* Industrial Combustible gas detector
* Portable gas detector


MQ2 will be applied to the beginning of the machine where functional as sensor. when the sensor operate, the output will be connected to the control system to operate the others system.

Design Poster and Submit to Supervisor.


Poster is one of the most important things while doing Final Project. It is important while presentation day. So that, this week for designing the poster that must be submit to supervisor. It is important to submit to supervisor before print it because supervisor can complain and alter some mistake that have done. Below is the poster for the first designing and final poster.


above are the poster that not finished yet


above are the final poster.

above are the poster of automatic smoke absorber machine.
