Fritzing raspberry pi diagram3/11/2024 ![]() ![]() USB to Serial TTL (optional for testing functions using the PZEM-004T Master application).Load (can use TL Lights / Bulb / LED / Electric Drill).In this example PZEM-004T V3 module program, some hardware is needed, among others : To find out more detail and complete about the differences and advantages between the two, please open the previous article : Get to know PZEM-004T Electronic Modules for Electrical Measurement ToolsĪs for the sample PZEM-004T V2.0 module program, please open the article link below :Įxample of the PZEM-004T V2 V2.0 Interfacing Program Using Arduino Hardware Required If using the example program with Serial Hardware, Arduino Mega2560 is needed because the Arduino UNO Hardware Serial is already used for communication with Serial Monitor.Īs I stated in the previous article, that the PZEM-004T V3.0 module is an upgraded version of PZEM-004T V2.0 and also the protocol for communicating the interface is different, the library program for PZEM-004T V2 cannot be used for interface with PZEM-004T V3.0. In this article, we will discuss the use or use of the PZEM-004T V3.0 module that is interfaced or programmed using Arduino UNO or Arduino Mega2560. ![]()
