ESP32 + HX711 for load cell

Post by Hackathorn » Thu Dec 20, 2018 9:36 am

Using load cell to measure real-time weight variations, which are remotely logged via WiFi for cloud analysis.
Problem is that ESP32 is 3v but the HX711is 5v.

1) Since it is remote IoT, I would like to use on-board LiPo. But how do I obtain the 5v for HX711?
2) What is the simplest way to level shift? Logic Level Converter board?
3) Can the ESP32 duplicate the function of the HX711? ...thus eliminating the problem!
