I have an old external b. The advantage of modems is that you can interact with the phone line for making calls.

A passive infrared sensor PIR is waiting for a person to enter a room.

If some movement is detected, it reports to a pic microcontroller. Finally the pic dials a phone number through the modem to alert the user. In the same way I used the ds because it can communicate with a serial port without a capacitor unlike MAX I have soldered some wires directly to the modem 1 for GND, 1 for 5 v. When this happens, it starts sending AT commands to make the alarm call.

Re: DS275 RS232 Level Converters

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. What you can see in the video is: 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.

The user has 15 seconds to leave the room, then the pic waits a motion detection. When it is detected the pic dials a fixed phone number and the user will receive the alert.

It is more complicated. You are talking about a camera and send the picture through MMS or email.

Since it is analog it does not work on digital phone lines. Do they make a digial sensor that will work or is there a attachment that will change analog to digital. Does not include photo attachment. Este sitio web utiliza cookies para que usted tenga la mejor experiencia de usuario.

I have an inexpensive motion sensor auto dialer that dials my cell phone if it detects motion. I would love to find a device that would do the same thing and send datashert a pic. Your invention is great but it helps if you have the technical smarts to do it.

Do you know if there is an off-the-shelf version of a picture sending auto dialer??? Uso de cookies Este sitio web utiliza cookies para que usted tenga la mejor experiencia de usuario.
