Tue Nov 10, 8: 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.

Users browsing this forum: I would love to find a device that would do the same thing and send me a pic. In the same way I used the ds because it can communicate with a serial port without a capacitor unlike MAX You should turn off the comparators as part of your initial register setup. Tue Nov 10, 9: Hi, thanks for your reply. Hi everyone, I’m working on a weigh scale with a strain gauge connected in the input RA2 of a dw275 16F Page 1 of 1.

Grounds and Vdds are hidden with proteus so Dataaheet don’t think problems come from there. Sun Nov 08, 3: Finally I changed the sub-d port and now it works however don’t know if in reality it will A passive infrared sensor PIR is waiting for a person to enter a room. Sun Nov 08, When this happens, it starts sending AT commands to make the alarm call.


Does not include photo attachment. Do you know if there is an off-the-shelf version of a picture sending auto dialer??? I have an inexpensive motion sensor auto dialer that dials my cell phone if it detects motion.

The user has 15 seconds to leave the room, then the pic waits a motion detection. Your invention is great but it helps if you have the technical smarts to do it. If some movement is detected, it reports to a pic microcontroller. I have soldered some wires datashest to the modem 1 datsaheet GND, 1 for 5 v. What you can see in the video is: Here is my program: Make sure there is 1 ground across both systems.


Do they make a digial sensor that will work or is there a attachment that will change analog to digital. It is more complicated.

Re: DS275 RS232 Level Converters

Did you have a negative voltage between pin 2 and 5 on the D-Sub? You are talking about a camera and send the picture through MMS or email. 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.

Mon Dec 31, 3: I have an old external b.

Since it is analog it does not work on digital phone lines. When it is detected the pic dials a fixed phone number and the user will receive the alert. No body can help me? Finally the pic dials a phone number through the modem to alert the user. 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.
