ESP32-CAM takes a picture, save it on the memory card and cut off the power so only the PIR sensor remains active. I need a external circuit to do this. The SR-602 sensor output signal is 3.3v for only about 2.4 seconds (not modifiable). If I use a transistor like a switch, ...

Thank you so much. This solved it for me. I should now be able to use other pins not being used by the SD card or camera? I want to add an external wake via a PIR sensor. Daveyman123 Posts:26 Joined:Sun Jun 16, 2019 5:37 pm ...

We can use external interrupt pins in various situations ranging from simple notification when a PIR sensor detects the motion of somebody in a room. And up to doing some measurement stuff and calculations like measuring the frequency of a digital sensor such as an “Optical Encoder” to measure...
