ESP32 uses less power. When you use deep-sleep, you can draw as low as 40microAmps, a sensor I've build on a ESP32 has been running for 3 months on the same bat

ESP32 uses less power. When you use deep-sleep, you can draw as low as 40microAmps, a sensor I've build on a ESP32 has been running for 3 months on the same battery and I expect one more out of it. The battery is a 2200mA LiPo 18650, so nothing that extraordinary either.
The Pi0W probably won't run a day on the same battery.
- KaiserPro 7y agoThe ESP32 has deep sleep, but it uses about the same power as the pizero when running. The ESP32 is a really power hungry: http://www.geekstips.com/wp-content/uploads/2017/10/esp32-power-consumtion-during-transmission.jpg http://www.geekstips.com/wp-content/uploads/2017/10/esp32-po... vs https://raspi.tv/2017/how-much-power-does-pi-zero-w-use https://raspi.tv/2017/how-much-power-does-pi-zero-w-use Considering that he pi as way more ram, an SD card and a GPU, and is running 4 times as fast. the important take away is that they have different use cases.
- zaarn 7y agoThough it's important to keep in mind that deep sleep can fairly long, if you use external triggers, you can go days or months in inactivity, which saves A LOT of power. Though I do agree it depends on your use case, if you're plugged into the wall, a Pi0 might be the better option.
