Hi 

 
I want to build a system contain sensor ,Microcontroller and GSM
module. I&amp;#39;ll use SIM900 GSM module. The main idea of this project if
Reed switch sensor connected I want the GSM module send an alarm
message to a mobile.

Thanks Mr.Per Westermark.&lt;br /&gt;
I think I&amp;#39;ll use 8051,I started learning how to program it.&lt;br /&gt;
I&amp;#39;ll try to finish it.&lt;/p&gt;

&lt;p&gt;

On what basis did you initially choose the 8051 at (or before) you
started this thread?&lt;/p&gt;

&lt;p&gt;
Certainly, nothing you&amp;#39;ve said so far is in any way beyond the
reach of an 8051&lt;/p&gt;

Take a microcontroller you have available. Or that you have
knowledge about. Or that you have access to tools for. It doesn&amp;#39;t
matter which you take. Any talk about &amp;quot;best&amp;quot; is just a big fail.&lt;/p&gt;

In fact I&amp;#39;m confused now! which one I&amp;#39;ll choose?? PIC,AVR or 8051
?!&lt;br /&gt;
My application is simple, so I think I can choose 8051 ?? I don&amp;#39;t
need to choose the best one ! ( I think that )..&lt;/p&gt;

&lt;p&gt;
What do you think??&lt;/p&gt;

you are right.But in my project I don&amp;#39;t need to these

&lt;i&gt;&amp;quot;The last survey said this&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
What &amp;quot;last survey&amp;quot; - by whom? when?&lt;br /&gt;
Give a link!&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;The 8051 has been around since 1957&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Nonsense! The integrated circuit as we know it was not invented
til 1958!&lt;/p&gt;

&lt;p&gt;
&lt;a href="http://en.wikipedia.org/wiki/Integrated_circuit#Invention"&gt;en.wikipedia.org/.../Integrated_circuit&lt;/a&gt;&lt;br /&gt;

&lt;a href="http://en.wikipedia.org/wiki/Intel_MCS-51"&gt;en.wikipedia.org/.../Intel_MCS-51&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;The pic has been around for a long time too [1989]&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
That sounds a bit late?&lt;br /&gt;
&lt;a href="http://en.wikipedia.org/wiki/PIC_microcontroller#History"&gt;en.wikipedia.org/.../PIC_microcontroller&lt;/a&gt;
suggests 1975&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;The avr is newest [2003]&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Another bad date: &lt;a href="http://en.wikipedia.org/wiki/Atmel_AVR"&gt;en.wikipedia.org/.../Atmel_AVR&lt;/a&gt;&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to interface Reed Switch sensor with 8051 Microcontroller?</title><link>https://community.arm.com/thread/153036?ContentTypeID=1</link><pubDate>Sun, 07 Oct 2012 14:07:15 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ed9d76fc-be6d-44de-bcba-f7191c1aa794</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
So the 8051 predates the invention of the microprocessor with quit
a number of years. Interesting.&lt;/p&gt;

&lt;p&gt;
Next thing - lots of PIC and 8051 processors are single-clockers,
i.e. one instruction/clock cycle.&lt;/p&gt;

&lt;p&gt;
Further - true RISC is not a really good thing. It means that
there are very few instructions that does very basic operations. You
then combine multiple instructions to solve more complex operations.
Many CISC processors can manage in a single instruction what it takes
a number of RISC instructions to get done.&lt;/p&gt;

&lt;p&gt;
In reality, the world have seen that neither RISC or CISC are
best. So most newer designs takes the best from both worlds.&lt;/p&gt;

&lt;p&gt;
So no - it is not obvious what is best. Especially since there are
so many &amp;quot;best&amp;quot; to chose from:&lt;br /&gt;
* best availability&lt;br /&gt;
* best operating voltage range&lt;br /&gt;
* best brutal processing power&lt;br /&gt;
* best low-energy operation&lt;br /&gt;
* best documentation&lt;br /&gt;
* best peripherials for the specific project&lt;br /&gt;
* best distribution channel&lt;br /&gt;
* best form factor&lt;br /&gt;
* best temperature range&lt;br /&gt;
* best compiler support&lt;br /&gt;
* best familiarity&lt;br /&gt;
* ...&lt;/p&gt;

&lt;p&gt;
By the way - you seem to have quoted a source. Why didn&amp;#39;t you
mention what source by supplying a link?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to interface Reed Switch sensor with 8051 Microcontroller?</title><link>https://community.arm.com/thread/152298?ContentTypeID=1</link><pubDate>Sun, 07 Oct 2012 12:58:34 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:9db73111-93e3-4aed-81be-31aeece52755</guid><dc:creator>h lambatrek</dc:creator><description>&lt;p&gt;&lt;p&gt;
The last survey said this;&lt;/p&gt;

&lt;pre&gt;

Any of these will do the job well for simple embedded applications.

The 8051 has been around since 1957 and there are many variations of it available from multiple sources.

The pic has been around for a long time too [1989]. There are many variations of it too, but it is single sourced by Microchop.

The avr is newest [2003]. It runs circles around the pic at the same clock speed since it is a true risc,
while the pic consumes 4 clocks per &amp;quot;risc&amp;quot; instruction.
The avr instruction set is more powerful than pic or 8051. It is also single sourced.

&lt;/pre&gt;

&lt;p&gt;
so it is obvious who is best.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to interface Reed Switch sensor with 8051 Microcontroller?</title><link>https://community.arm.com/thread/151493?ContentTypeID=1</link><pubDate>Sun, 07 Oct 2012 07:37:06 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:a7b13df2-8b34-4185-8304-170d9b4921ef</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
Indeed.&lt;/p&gt;

&lt;p&gt;
The general principles are the same whatever chip you use. If you
just give up and switch chip as soon as you hit some specific detail,
you will never finish anything.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to interface Reed Switch sensor with 8051 Microcontroller?</title><link>https://community.arm.com/thread/146935?ContentTypeID=1</link><pubDate>Sun, 07 Oct 2012 05:39:58 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4ff70d98-b06e-4d81-81f8-29bc1b4f0d18</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
Probably because he randomly thinks PIC are easier, because he
might have seen a schematic with a switch (maybe even a reed switch)
connected to a specific PIC chip.&lt;/p&gt;

&lt;p&gt;
In the end, the complexities are similar if using 8051, PIC, AVR,
...&lt;/p&gt;

Thank you Mr.Per Westermark.Now I know I make a mistake,I did not
specify my question.Now I will read about all components of my
project to get good knowledge about them,and if I face a problem I&amp;#39;ll
put a specific question.&lt;/p&gt;

&lt;p&gt;
Now I think learn and read about programming PIC.&lt;/p&gt;

Your question was how to interface reed switches with a
microcontroller.&lt;/p&gt;

&lt;p&gt;
And the simple answer is: just like you interface other switches
with a microcontroller.&lt;/p&gt;

&lt;p&gt;
So that should keep a final year computer engineering student
going.&lt;/p&gt;

&lt;p&gt;
In fact - a final year computer engineering student should be able
to figure out himself that a reed switch is just a specific form of
switch and be able to go from there. That would follow from reading
the datasheet of the specific reed switch together with the general
information available at:&lt;br /&gt;
&lt;a href="http://en.wikipedia.org/wiki/Reed_switch"&gt;en.wikipedia.org/.../Reed_switch&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;
So exactly why are you asking? What issues did you see that made
you feel a need to ask how to interface a reed switch with a
microcontroller? To get good, specific, answers, you have to write
good, specific, questions.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: How to interface Reed Switch sensor with 8051 Microcontroller?</title><link>https://community.arm.com/thread/140400?ContentTypeID=1</link><pubDate>Sun, 07 Oct 2012 01:29:09 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ace1592c-63b5-4eb4-a843-6c527f665527</guid><dc:creator>Andy Neil</dc:creator><description>&lt;p&gt;&lt;p&gt;
You&amp;#39;re a &lt;b&gt;&lt;i&gt;final&lt;/i&gt; year&lt;/b&gt; student, and you don&amp;#39;t know
that?!&lt;/p&gt;

So your teacher thought you should do a microcontroller project to
_force_ you to spend time and learn. And you ask on a forum how to
get someone else to supply a solution so you won&amp;#39;t have to learn?&lt;/p&gt;

&lt;p&gt;
Talk with your teacher if you find it so repulsive to spend time
and learn about microcontrollers.&lt;/p&gt;

You are right, but my teacher told me you must do this project to
improve your skills in Microcontroller field.&lt;/p&gt;

A &amp;quot;student&amp;quot; is someone who &lt;i&gt;&lt;b&gt;studies&lt;/b&gt;&lt;/i&gt;.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;&amp;quot;I&amp;#39;m weak in Microcontroller&amp;quot;&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
So that&amp;#39;s were you need further &lt;b&gt;study&lt;/b&gt;, then!&lt;/p&gt;

&lt;p&gt;
But why choose a project in your weak area?!&lt;br /&gt;
Surely, it would be better to choose a project where you can best
display your &lt;i&gt;strengths&lt;/i&gt;...?&lt;/p&gt;

Are you sure you have the basic knowledge for this project?&lt;/p&gt;

&lt;p&gt;
There is nothing magic with reed switches - they are switches, so
are interfaced like normal switches.&lt;/p&gt;

&lt;p&gt;
And yes - to do anything with a GSM module you really do need to
learn how to send and interpret the &amp;quot;AT&amp;quot; language the modules are
using.&lt;/p&gt;
