ESP32 Forum

Hello,
I am facing problem with interfacing ESP32 and HLW8032 Module, I am getting garbage values on serial monitor when trying to run one of the codes from the examples of HL8032-master library. Can anyone please help me with connections?

Hi, a very common reason for garbage value in the serial monitor is baud rate mismatch. Please check if there is any baud rate mismatch between what you defined in your code and the serial monitor. In the meantime, if you're interested to make a more simple energy saving system, you can take a look at this:

Hey the baud rate is same. The problem is that the sensor gives output in 24 bits that too in hexadecimal. so i want the approach to deal with this array of 24 elements.
