Activate PIR xmtr
Suggestions please.
Taking a driveway PIR xmtr to modify for other purposes with no actual internal mods. Thinking of using some emitter taped to the PIR window to activate the xmtr. Something as simple as a blinking LED to keep the xmtr transmitting while the LED is blinking. Using one of these. 4VWIN Wireless Home Security Driveway Alarm https://www.amazon.com/4VWIN-Wireles...e+door+monitor or Harbor Freight Home Security Driveway Alarm https://www.harborfreight.com/wirele...tem-62447.html Suggestions please. Switch State Open - LED off and no PIR activation Closed - LED blinks to maintain PIR activation. Option 1: blinking LED and switch and battery. Option 2: 555 timer, LED, switch and battery. Or ??? What is needed to activate the PIR. LED color or type ? Receiver will just be the reeiver's flashing LED with the audio function disabled. I think it is a transducer that I can either smother or cut out of the circuit if it is not part of the receiver function. What do you think? |

When looking for the LED, what description do I look for ?
I have never seen anything called a thermal LED. DigiKey have them. Their on-line catalog is impossible to find anything especially LEDs. Any part number for me ? I am trying to build a garage door monitor. My new garage door opener does not have a lock function like my previous so I need a way to monitor the door state in my house, The driveway monitor is almost all I need and if I had a schematic I could modify it internally. Looking at the circuit board does not give enough info. Jasen Betts wrote: On 2018-09-23, OGER wrote: Suggestions please.

You could pick off a signal from the down limit switch to drive a transmitter or direct wire to a led inside the home or whatever. |

I have never seen anything called a thermal LED. you need a heat emitter, not a light emitter, use a small heat source, like a small lamp or a resistor an LM555 powered by 5V blinking a 0.3W 6V lamp would probably do the trick digikey part number CM756-ND is a 14V lamp but using lower voltage will make it last longer and produce more infrared than a 5V lamp Wire the 555 discharge and output pins in parallel, this lamp is borderline max load for a 555 so combining the two outputs will help.. ----+-----------------+-- +5V 1Meg | | +-[R1]--------|--------+--(@)---+ | | | | +--------+ | lamp | | | | | | . . . .|. . . . | | | .

Because it is there !
The least mod to the driveway monitor is desired. That way if in the future the PIR xmtr fails I can simply replace it or the receiver if it fails. So making the PIR detect something and activating the transmitter so the receiver will flash as it normally would. Terry Pinnell wrote: OGER wrote: snip I am trying to build a garage door monitor.

I wired magnetic alarm switches on my garage doors, stole power for the circuit from the IR "eye" circuit, and ran it to bright blue LED's right inside my service door in the house. They are mounted in a low voltage box. Super bright and easy to see from across the whole lower level of the house. |

Mine is a tilt up door that the wind will wiggle so a magnetic switch
probably will not remain aligned. anyway, for $12, I get a PIR transmitter and receiver with a specific channel assignment. No wiring between them is required. battery life is over a year for the xmtr since I use an external battery pack. I currently use such a setup to monitor motion in my home and the xmtr gets activate many times during the day proving battery life.

Obviuosly so I could see if I could remove the PIR detector and substitute a mercury switch for garage door tilt up. Modify the receiver to eliminate the sounder and substitute brighter LEDs for the three that currently are part of the design. John S wrote: On 9/23/2018 2:11 PM, OGER wrote: Suggestions please.

I am not a troll but I can see that many here have big prejudice problems.
Some think they are so smart and they are generating fake news right here. I come here seeking help to a problem and get hog wash. A few did make some suggestion worth investigating. Thanks to them. Strange group here. A friend of mine gave me the best suggestion and he is only a technician. |

No muss, no fuss. Peter Wieck Melrose Park, PA That's a very similar magnetic switch to the one I installed. Only I placed mine at the top of the door, on the header. Magnet is on the door itself. A lesson learned is do NOT buy the cheap 50 cent plastic bodied magnetic alarm switches, buy the good quality switches as shown. Save yourself a ton of aggravation. |
