We need a UART TTL to RS485 converter module.
MODBUS RTU ARDUINO PROTEUS SERIAL
Since this AC Energy Measurement Device uses RS485 communication, we need a converter module that can convert RS485 to Serial communication in order to communicate with Arduino board. Has it convinced you? Let’s get started !
It acts as the AC Power sensors for Arduino so that only minimum wiring and work is required comparing you buy and wire all the modules individually and create their own individual part of codes.
MODBUS RTU ARDUINO PROTEUS CODE
You can use the values for further processing by adding Arduino Code to the measured values such as recording them using Datalogging Shield, or display them using LCD Display Shield just to name a few. T oday I will show you how easily to read the measurement values using Arduino UNO. It sounds complicated and useless, but not with Arduino microprocessor board. The measured values can be displayed on your PC using UART to RS485 converter with its come-along software. It has a built in RS485 communication interface using Modbus-RTU protocol similar to most industrial devices.
PZEM-014 and PZEM-016 both do not have Display on it, that is why it is cheap to own. These 2 models can measure Voltage, Current, Power, Energy, Frequency, and Power Factor. Peacefair is a very famous Chinese brand with good quality and price that specialize in Metering products. PZEM-014 (measurement up to 10A direct connection) and PZEM-016 (measurement up to 100A indirect connection using Current Transformer) are AC Energy Meter from Peacefair.
