mmWave Radar Sensor (LD2420) - batterie + esp32 d1 mini

ESPHome
1

I’ll configure the esphome with a LD2420 sensor this week, i create (as my first 3D model) a case for the following parts:

  • esp32 mini d1
  • battery shield
  • ld2420
  • LiPo battery

The look & feel is low, first try. To havé the STL, follow the link:

HI
How long does it last between charges?

Interested as well. I thought the LD2420 was quite power hungry, with a “plain” motion sensor to mitigate.

Yes, and this kind of battery will be up for 22hours max.

So I create a new topic without battery.
