Arduino communication library for Peacefair PZEM-017 v1.0 Energy monitor, a slightly modify version of Jakub Mandula's PZEM-004T-v30 library (https://github.com/mandulaj/PZEM-004T-v30)
Make sure the device is connected to the 5v power!
#include <PZEM017v1.h>
/* Use software serial for the PZEM
* Pin 4 Rx (Connects to the Tx pin on the PZEM)
* Pin 5 Tx (Connects to the Rx pin on the PZEM)
*/
PZEM017v1 pzem(4, 5); //WMOS D1 4=D1, 5=D2
void setup() {
Serial.begin(115200);
}
void loop() {
float voltage = pzem.voltage();
if( !isnan(voltage) ){
Serial.print("Voltage: "); Serial.print(voltage); Serial.println("V");
} else {
Serial.println("Error reading voltage");
}
float current = pzem.current();
if( !isnan(current) ){
Serial.print("Current: "); Serial.print(current); Serial.println("A");
} else {
Serial.println("Error reading current");
}
float power = pzem.power();
if( !isnan(power) ){
Serial.print("Power: "); Serial.print(power); Serial.println("W");
} else {
Serial.println("Error reading power");
}
float energy = pzem.energy();
if( !isnan(energy) ){
Serial.print("Energy: "); Serial.print(energy,3); Serial.println("kWh");
} else {
Serial.println("Error reading energy");
}
Serial.println();
delay(2000);
}
You should be able to install the library from the Library Manager in the Arduino IDE. You can also download the ZIP of this repository and install it manually. A guide on how to do that is over here: https://www.arduino.cc/en/guide/libraries
Thank you to @olehs and Jakub Mandula for this great library.
