sms door lock

Would you please provide us with more details about what you want to do?
For example; the cell phone model used, the microcontroller,..etc.
Also, you can take a look at this topic:


Hope this helps.

sms electronic lock

Hi, I planing to use any PIC micro (for example 16F877, 876...) with nokia 3310,
I want to send SMS to this mobile for opening and closed electronic door (if is possible with one level of protection for example only 2 or 4 incomming number phone to have possibility to do this) ... the last is not very important...
regards

First, make sure this phone has a serial port and supports the 'AT' command set. You may want to consider using a GSM module instead.

This is a simple and straight forward app. You communicate with the phone/modem by sending command strings to it. Every command starts with the characters "AT" - hence they are refferred to as 'AT Commands'. When you retreive an SMS Text message from the phone/modem it will have the phone number of the sender emebedded in it. It is easy to compare that number to a prescribed list of numbers.

One thing to consider with SMS text messaging is that there is no guarantee when the message will be delivered, if at all. Messages are sometimes 'lost' and it can take several minutes for a message to be deliveried. You should incorporate some type of response from your device to indicate that it's received a message - for example, send a message back to the caller indicating receipt of their message.

cell phone lock door

Hi for all in this topic, I need practical example,
can somebody share with me some finished project,

connect an electronic door lock to a phone?

We experienced the same problem before when we were trying to find a suitable cell phone for our project. The most suitable one was Nokia 6610 as it has a serial interface (RS232) and support text mode messaging.

With the Nokia 6610, all you need to do is to connect the TX pin of the cable to your RX pin of the MCU, the RX pin of the cable to the TX pin of your MCU and finally, the GND of the cable to the GND of the MCU.
Now, you can send what you want to the Nokia 6610 using simple "AT-Commands" as mentioned above by GSM Man

You can find a tutorial about the "AT-Commands" in the below link:

Hope this helps.

teltronika gsm module

you can connect nokia 3310 mobile to microcontroller using FBUS protocol....

so search about FBUS protocol...

you have to connect 3 pins of mobile to microcontroller

if u r using controller with 5 V power supply then you have to use 4050 ic which is voltage compatible ic...

this is the link for FBUS protocol

sms gsm send sms with guarantee at command

I think i have solution for you.
TwoWay Thing has 4 relay outputs and 4 sensor inputs. It also has EN (sensor enable) pin.
This project is using PIC16F628A and nokia 6210,7110 or 6310i.

It would be better to use aphone supporting at commands.Its much simpler than 3310 and resourcs are easily available on net

electronic lock sms

Using AT commands is easier.
U can add some kind of musical buzzers for audio indication.
Audio indication enables u 2 know if the message u hav sent is received or not.

Interfacing with mobiles may be bit confusing for you
Because you don't know what commands it supports
u can use GSM/GPRS modems for ur application
These modems support AT commands
The manufacturer of these modems provide user manual which u can go through n
use d specific commands.
n moreover if u want a housing for your product it would be better to use modems
because u can integrate these modems onto same pcb as microcontroller.
using mobiles makes ur circuit looks bulky n special cables have to be purchased.

u can use TELTRONIKA TM2 Module
or a low cost SIM300/SIM340 modules

check out the above link.
It may be helpful for u in designing your relay circuit.

could you pls share with us here

pls what is the output voltage and current of a PIC 16F877 microcontroller? This values would help me in my project too. I am doing the same project: SMS controlled electronic door lock. pls if anyone has done it, please let me know so that we can share ideas.

i need ur help fr d above given project
pls wud u send me d synopsis of dis project

The full datasheet for the 16F877 is available for download : www.microchip.com

(Just type the number in the search box at the top of the page.) They also have a very wide range of project examples you may find helpful

Hey guys, Im looking for someone in Manchester UK who can create a sms based system which lock and unlock from a remote location, It would also need software so that a member of staff would not be able to simply look at the number and open the lock, the project is potentially very very lucrative but I have no patent on the specific idea, so I cannot go into specifics on a public forum, please get in touch if you want more info, please include your credentials as I cant be doing with dreamers, only serious people please.
