Hi Everyone,
I have a small project I need to make. I have a Parallax PIR sensor (PDF attached). I have a recording device that turns on with the push of a momentary tactile button. I want to replace that button with the PIR. I need something that will take the TTL signal and momentarily close a contact. I can't use a relay due to the clicking sound it will put out. It MUST be silent. I don't know of any other alternatives except a solid state relay. I'mhoping there is another method I can use. It needs to run on 5vdc. I will use a type 4LR44 6v battery with a 79L05 voltage regulator. I need to keep size down also. Any help would be greatly appreciated.
Regards,
Dennis
