ESP32 power options in c/[email protected]

Thanks for your insights. I was planning to use mmWave (LD2410?), PIR, BLE tracer and luminance sensor with custom 3D printed case.

Basically, what EverythingSmartHome proposes but ideally, cheaper. And I’ll be able to updates parts of it as technology evolves (i.e. mmWave).

Thanks for your reply. I missed the fact that the Olimex supports 5V, that makes it the best option so far! I’m planning at least 14 sensors so I’m trying to keep it cheap. Everythingsmarthome version of ESP looks nice but as I’m not in the UK, their import taxes make it really expensive for me.

ESP32 power options (alien.top)
 

Hello,

I’m currently building a new house (EU). I’m planning to put ESP32 sensors in every room (top corner) with mmWave sensor to have a reliable presence detection.

I don’t know what the best way to power the esp32 is? Wi-Fi coverage should be good enough, so Ethernet is a plus but not mandatory.

POE looks nice but might require a bigger box as ESP32 with Ethernet looks bigger? Also, I’m not sure it will be able to power the mmWave sensor? I only saw 3.3V output. Any recommendations?

5V run from a central location (garage) might be difficult with voltage drop. Any recommendations for some cable specs and maybe experiences?

Last option would be a regular 230V run with 230V/5V transformer next to each ESP32, which also leads to a bigger box.

What do you think would be the best option?

Thank you for your advice!
