addressable sensor

i make wireless fire alarm & security system

in fire alarm
i designed heat & smoke &Gas &beam &flame&manual call point (all this sensor addressable)
i want to ask how can i design this addressable sensor & and i want to ask also : i must put with every sensor pic micro controller to make address

i want to know all things about the addressable

Answer my Q's and I will give you U'r diagram.

And I want to know who you are and where u are from?
Also I want to know how old are you?
I want to know why you want so much things in the first place?

i am ali form egypt

20years

because i make project and i need this info very match

OK ..Ali from egypt...

tell me ur electronics skills...what u know and ur experience in soldering.

i know very well mikroc pic

PCB principle

basic electronic circuits

Then just draw what u need in MS paint or corelDraw.

Give me the basic Idea of the project.

shortly

i make completing addressable fire system connecting with fire station

and security system on the control room connecting with police station.

i need the idea of addressable sensor .

connect the sensor with dip switch or pic to make address and connecting it to control panal

What U say makes no sense to me...cause Ur English is weak.

So better to draw and show ur idea.

ok i will draw my project and i will send it to you

Just post it here.

You could use 2 MCUs.

One (MCU_1) could be the sensor controller and would monitor all the sensors, do any conversion or scaling required and store their current value or status.

The other (MCU_2) could be the alarm controller and would be responsible for alarm triggers, arming and communications.

MCU_2 could query MCU_1 on a regular basis to get the current sensor status and respond accordingly. Communication between them could be done through one of the popular serial protocols.

can you help me to design this sensor

please check the attach(smoke sensor)


i will design with pic 16f877a

Hardware and prog

i used mickro C

Roman Black has a pretty good way of doing this.

You can get the cheapest little 10F pic, attached to the sensor..as many as you want.

It only requires 1 wire communications. The PIC and sensor can be battery operated, and connect to a MASTER station.

Here is a link to the details:
