PZEM-016 are normally RS485, I modified them to be UART 3.3V compatible
- Remove MAX485 IC
- Short-circuit pin 1 to 7 of MAX485
- Short-circuit pin 4 to 6 of MAX485
- R 3k3 0805 between pin 5 and 7 of MAX485 (do warn of short-circuits under resistor on pin 5-6-7)
- R 2k2 0805 between pin 3 of U1 and R13

I like this monitoring system. Is this good idea to embed it on dynamic project? I want to setup it on my blog post of https://bestdehumidifier2021.com/best-dehumidifier-brands/
