When it is detected the pic dials a fixed phone number and the user will receive the alert. Does not include photo attachment. The advantage of modems is that you can interact with the phone line for making calls.

Here is my program: Do you datasheeet if there is an off-the-shelf version of a picture sending auto dialer??? Page 1 of 1.

Since it is analog it does not work on digital phone lines. Users browsing this forum: Grounds and Vdds are hidden with proteus so I don’t think problems come from there. You should turn off the comparators as part of your initial register setup.

What you can see in the video is: Sun Nov 08, 3: Do they make a digial sensor that will work or is there a attachment that will change analog to digital.


It is more complicated. I have soldered some wires directly to the modem 1 for GND, 1 for 5 v. If some movement is detected, it reports to a pic microcontroller.

The pic is coded in mikroC and my problem is at the level of the connexion between DS it’s a max without capacitors and the SUB-D port the circuit will be able to connect to a pc. When this happens, it starts sending Ds2775 commands to make the alarm call. Mon Nov 09, Once the call has been made and the modem detects that the call is ended, it returns a numeric code that the pic receives and change to detection mode again.

Hi everyone, I’m working on a weigh scale with a strain gauge connected in the input RA2 of a pic 16F I have an old external b.

Did you have a negative voltage between pin 2 and 5 on the D-Sub? The modem is turned on and the pic configures it to disable command echo, change to return numeric dstasheet and turn off dztasheet volume of the modem speaker. No body can help me? I would love to find a device that would do the same thing and send me a pic. A passive infrared sensor PIR is waiting for a person to enter a room.

Previous topic Next datasheey. Make sure there is 1 ground across both systems. Your invention is great but it helps if you have the technical smarts to do it.

Sun Nov 08, Hi, thanks for your reply. Finally I changed the sub-d port and now it works however don’t know if in reality it will Finally the pic dials a phone number through the modem to alert the user.

You are talking about a camera and send the picture through MMS or email. I have an inexpensive motion sensor auto es275 that dials my cell phone if it detects motion. In the same way I used the ds because it can communicate with a serial port without a capacitor unlike MAX
