Pressure Sensor alarm with PIC16F877A to activate the bulb

[jayanth.devarayanadurga]

What is the min and max value of pressure you are measuring and what are the corresponding adc value you get for min and max pressures?

 

[jean12]

I don't know the pressure I am measuring I am applying on the sensor a small air pump which I use normally when making PCBs, so as I don't know its pressure I just wanted to test if it is possible to change the pressure by applying that element then I can interface to the PIC for switching purposes.

the output I have is the same as the one I have when applying that pump;

Use a sensor which is giving more output than the 2100, whta is your pressure range? use 5010 instead of 2100 ( If your pressure limit is less than 10Kpa)

I want to design a sensor which when applied an Air compressor for example,on MPX2100 in a given limit it has to sense and activate some other components in the circuits like a bulb for example.

It is clear that this sensor will be applied on analogue input of a PIC;what will be the codes to use?

Thanks.

whats your pressure range? and what resolution you want?

 

[jean12]

My pressure range is unknown I am using an air pressure (TECAX AP1500)which I normally use for PCB Making;it has low pressure.

Thanks.

My pressure range is unknown

before starting the design, better to understand the design criteria s. Otherwise the design will not be a good one

if your pressure range is less than 10Kpa, the you will get a linear output from mpx5010.
