This ESP32-CAM Remote PIR can work independent or in conjunction with the ESP32-CAM Video Recorder I also posted in github. This ESP32-CAM Remote PIR has the following capabilities:

• Wake from PIR and do the following:
  • Optionally send a remote trigger to an ESP32-CAM Video Recorder with the following options:
    • Take a picture.
    • Take a picture and email it.
    • Make a video.
    • Make a video and send an email with name of video.
  • Optionally email up to 6 pictures or a 10 second AVI video.
  • Go to deep sleep.
• Wake from a time trigger and do the following:
  • Optionally email one picture.
  • Run a webserver for 10 minutes with the following options:
    • Refresh image.
    • Start/Stop a video stream
    • Email a picture or a 10 second video.
    • Access settings.
• Firmware updates Over-The-Air.
• No SD card required.
• Solar powered using a single 18650 battery per the attached schematic.
• Battery voltage indicator is connected to GPIO12.
• PIR motion sensor is connected to GPIO13.
• Pictures are JPG and videos are AVI.
• Uses a simple email utility I enhanced to send buffers or files which embedded in this sketch and is also now found on github.

See ECRP_Schematic.jpg for a picture of the wiring.

Used pinMode(GPIO_NUM_13, INPUT_PULLDOWN) in the setup to pull the pin low. Now when motion is detected, GPIO13 will be pulled high, otherwise it will be low.

I 3D printed an enclosure and bracket for holding the solar panel. ECRP_Enclosure.jpg shows the completed project.

The Default Partition Scheme must be used for compiling so OTA can work.
