Replacement of IR switch with reed switch?

Open patrick-kiwi opened this issue 1 year ago • 2 comments

I love this project. Thank you for open sourcing it. I wanted to replace the IR sensor with a reed switch, but there's a problem because if the reed switch stays closed, then the voltage regulator will stay locked on. I saw a possible workaround involving a few components. I pasted the LT-spice simulation. Current draw is zero except at the moment the switch closes. Just wondered what you thought?

Hi Patrick, Are you using the old version of the sensor or the new one ?? in the new version, https://github.com/PricelessToolkit/MailBoxGuard/blob/main/PCB/MailBox_Guard_Schematic.jpg

I implemented the one-shot trigger. based on "TPS3839"

Oh yes thank you. I was using your old design because I have most of the bits in my workshop. I see what you mean with the new schematic. Thanks for replying.
