temperature monitoring 18f4550

Hi every body,

i am going to start new project that is as following:

1. monitoring and access to the security cam from your 3G mobile
2. control the temperature and other devices from the mobile.

can any one help me to start, i al looking first to the hardware, because i am still confuse which micro controller can be used for this design.

best regards
 

18f4620 application

You could use a PIC 16F/18F series micro-controller for the temperature and control of other devices.

16F877A data sheet https://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010242

18F4620 Datasheet https://www.microchip.com/wwwproducts/Devices.aspx?dDocName=en010304

The 16F877A is a good series for developing some applications, the 18F4620 is pin-compatible with the 16F877A but has more RAM and ROM. This could be useful for web server applications, USB connectivity or other high end interfaces.

Also how would you control the devices from the mobile via bluetooth, GPRS, internet or SMS or Email ??

I am not sure you could use the PIC for controlling a Web cam, as this is quite complicated for a PIC, you probably have to go in for a high end processor from Freescale, Atmel or even Arm.

Another alternative is to use a laptop or a PC that is connected via serial port to some low level hardware interfaces (consisting of relays and temperature sensors also web cam), a software on the PC could be used to manage these devices remotely via internet. This setup has the advantage that only the high level software needs to be developed instead of specialised firmware required for the processor.

Also the implementation and testing of this software is easily done as compared to the micro-controllers.

Hope this helps...

thanks

16f877 web server

thank you so much for reply, one of the things i am worry about the level of micro controller is 16 or 18f or higher in number of bit to combined the cam with the design. if there any relative project or design with data sheet will be very useful for me. thank you so much again.
 

vinculum webcam

what kind of cam (camera ??) are you planning to use ??

A web can is normally USB based and can only be connected to a USB host controller, (the host controller issues USB commands to the slave device), the PIC cannot be a controller as the amount of code required to implement this is considerable and also time consuming.

An independent USB host controller can be used instead, See

thank you arbj for ur answers, but are you sure the cam will work with the usb, i means there is no any types of image processing needed in the design. bcz i have board the contain the usb and micro controller, 64 pin.
best regards
 

Please mention what board and web cam you are using.
To run a web cam via USB you probably need an operating system like Windows or Linux..

thanks

for the bluetooth I'd you the cheap and easy to use module from Eikon Italy www.eikonsite.it
Transparent UART/RS232, settable

Hope this info helps you
