Hello, I would like to put my openMV in sleep mode when there’s no object in its view for a while and wake it up once a new object enters the view. I, however, am not too sure what the sleep functions end up doing and which is the best way to go about it. The following are my concerns/questions: *…

Hello, **- I notice that there’s pyb.stop and sensor.sleep. If I only do pyb.stop, then does that leave the camera on with the ability to process images still? If so, using Frame Differencing, can I wake up the hardware from pyb.stop when an object is detected? Or, is the wakeup strictly with an …

Hello, Thanks for the response! So generally, if I do pyb.stop, I should just do sensor.sleep(True) as well? Because if I don’t, the camera will just be on but can’t process any images. Is there an advantage in keeping the camera on while the board is on sleep? I’ll try it with an external interr…

Yeah, you can sleep the camera too.

Is there an advantage in keeping the camera on while the board is on sleep? It takes some time to wake up the sensor (a few 100 milliseconds) and for the sensor auto functions to settle.

Great! Thank you for your response!

Hi there, I have follow-up questions: When the main board is off (pyb.stop) and additionally the camera (sensor.sleep) is off: is this the “deep sleep” mode I found in the examples? what is the power consumption for both use cases? Is any of these the “idle” power consumption figure of 140 mA @3.…

[image] Latest Power Consumption Numbers OpenMV Products The H7+: stop mode + sensor on → 28mA stop mode + sensor shutdown → ~10mA standby mode → 6.8mA The H7: stop mode + sensor shutdown → ~10mA standby mode → 2.6mA
