ESP32 Forum

HI folks,

I am trying to build a little security cam for my front door, similar to a Ring doorbell system but without the doorbell or 2-way conversation functionality. Essentially it will be mounted to my doorframe, activcated by a PIR sensor so it detects when someone is near the door, takes a photo, and sends it to a storage device on my network.

I've got the following hardware to build it:
- ESP32 cam dev board - https://www.amazon.co.uk/dp/B0CJJHXD1W? ... asin_title
- HC SR501 PIR sensor - https://www.amazon.co.uk/dp/B096ZGLNPM? ... asin_title
- AdaFruit Powerboost 1000 charger board - https://www.amazon.co.uk/dp/B01BMRBTH2? ... asin_title
- LiPo 3.7v 2000mAh battery - https://thepihut.com/products/2000mah-3-7v-lipo-battery
- Solar panel to power the charging circuit - https://www.amazon.co.uk/dp/B0CTMN9CFY? ... asin_title

**Am I missing anything as far as hardware goes?**

Chat GPT has given me some instructions and a wiring diagram to show how everything hooks up but as usual with AI, it's a bit cock-eyed, the PIR sensor is wired to the breadboard and then nothing else haha.

I have an idea how they should all hook up but figured I'd ask all you good folks for some advice/confirmation.

I think the connections should be something like:
Battery to Powerboost 1000 board via the JST connector
Solar panel to Powerboost 1000 board via the micro-USB connector
Powerboost 1000 board to ESP cam board via USB-A on PB1000 to USB-C on ESP32 cam board
PIR data pin to relevant GPIO on ESP32
PIR +ve and GND pins to 5v and GND pins on ESP32 board.

Boards connected via USB should already have their V and GND connections handled "internally"

Is this correct?
