Does not include photo attachment. 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. Finally I changed the sub-d port and now it works however don’t know if in reality it will In the same way I used the ds because it can communicate with a serial port without a capacitor unlike MAX Tue Nov 10, 9: Here is my program: When it is detected the pic dials a fixed phone number and the user will receive the alert.

If some movement is detected, it reports to a pic microcontroller. Sun Nov 08, Sun Nov 08, 3: Make sure there is 1 ground across both systems. Previous topic Next topic. Your invention is great but it helps if you have the technical smarts to do it. I have an inexpensive motion sensor auto dialer that dials my cell phone if it detects motion. Grounds and Vdds are hidden with proteus so I don’t think problems come from there.

Do you know if there is an off-the-shelf version of a picture sending auto dialer??? Once the call has been made and the modem detects that the call is ended, it returns a numeric code ds725 the pic receives and change to detection mode again.

Did you have a negative voltage between pin 2 and 5 on the D-Sub? I have soldered some wires directly to the modem 1 for GND, dz275 for 5 v. You should turn off the comparators as part of your initial register setup. I have an old external b. What you can see in the video is: Do they make a digial sensor that will datawheet or is there a attachment that will change analog to digital.

The advantage of modems is that you can interact with the phone line for making calls. Hi, thanks for your reply.

When this happens, it starts sending AT commands to make the alarm call. The modem is turned on and the pic configures it to disable command echo, change to return numeric responses and turn off the volume of the modem speaker.

A passive infrared sensor PIR is waiting for a person to enter a room. Mon Nov 09, Users browsing this forum: Hi everyone, I’m working on a weigh scale with a strain gauge connected in the input RA2 of a pic 16F Since it is analog it does not work on digital phone lines.
