Trying to send a photo+avi right after wifi connects

[FBMinis]

I put together a simple circuit that turns ON and keeps the camera ON while the output of the PIR is HIGH.

I would like to receive a photo and an avi right after the camera connects to wifi (im using v8.9 to keep it simple without wifimanager)

I though I just had to call xTaskCreatePinnedToCore( the_camera_loop, "the_camera_loop", 10000, NULL, 1, &the_camera_loop_task, 1); by the end of setup() function but Im only receiving a photo, not the video.

The Serial Monitor seems to show the avi was recorded, but I dont received it.

SOLVED by adding the following line just before the end of the Setup function:

bot.longPoll = 0; xTaskCreatePinnedToCore( the_camera_loop, "the_camera_loop", 10000, NULL, 1, &the_camera_loop_task, 1);

The PIR detects movement, pulls the gate of the n-mosfet High, which pulls the gate of the p-mosfet Low, powering the camera for as long as Tx potentiometer sets it to. A photo and an video are immediately sent upon boot, then it waits for new messages as normal.

This is suitable for battery use, like keeping it in my car outside, over my doorstep or terrace, where I don't have access to mains line.

I use 4xAA batteries because I'm eerie of lipos. They are 2200mAh, the quiescent current of the PIR is 50uA and the project consumes 170mAh while running. In theory, if it detects movement once per hour, it should run for nearly 2 months.

Any suggestions for improvements would be welcome.

Interesting -- I'll have a look at that - some mods coming: add the modified radu light sensor, that hd issue, and the old picture issue

I've been able to make the project work at 3.3V consistently by using an HT7833, through which the PIR and Camera are powered:

https://www.holtek.com.tw/documents/10179/82844a36-1633-498c-a6e3-4d99f2d0f6d7

The PIR module was modified to work at 3.3V by moving the diode to the side, then connecting VCC pin directly to another pin close to the corner of the pcb where re-triggering is set.
Battery: 4xAA alkaline
Current when there's no movement: 70uA
Current while the camera is sending photo and clip: 200mA

In theory, with 10 wake-ups a day and 2000mAh batteries, it should last over a month and a half.

Have you tried these:

The big pir (with the 4 big capacitors at the corners) can power a small circuit (leds etc), but these little ones just give you a signal that a transistor or gpio can read, so less power required. Big pir is more configurable though.

Is an "event" here a single picture, or a 3 mb video?

[FBMinis]

I haven't tried other PIR modules as I already had about 10 of the 4xCapacitor ones - that's the only reason. That SR602 is smaller but seems to be well documented and has the same functionalities, I'll check them out.

In the battery operated project, a picture, video and message are sent when movement is detected. It takes about 1min for the picture and video to be sent, the PIR can be regulated to stay ON for that amount of time or up to 7min, giving us time to request more photos or videos.
