  How to read data analog from 4-20mA port?
Posted by: abgran - 09-25-2022, 11:13 AM - Forum: KC868-A4 - Replies (12)

Hi. I have already bought 6 units of KC868-A4 model on Ali Express Order ID: 8154057463938467. There are 2 ports for 4-20mA. I have a TDS sensor output 4-20mA range 0-4400 us/ms. 

Got 2 question.

1) Can you give a source code how to read from the 4-20mA port? 
2) If my sensor signal 4-20mA to 0-5v is using 250ohm right? Can you show the diagram how to connect. Thanks.

My TDS sensor have a 3 wire (+,  - & Signal (S1)).

  Nextion display work with KC868-A4
Posted by: admin - 09-23-2022, 02:59 AM - Forum: KC868-A4 - Replies (5)

i have removed RF433M receiver, RF433M sender and IR receiver. actually use want to use VCC,GND,RXD,TXD for Nextion display.

define RXD:GPIO23 TXD:GPIO21 by ESP32

here are some photos:
   
   
   

This just a simplest demo, use Nextion display two buttons, press button-one will send 'a' by serial port, press button-two will send 'b' by serial port.
when KC868-A4 received 'a' will turn ON relay1, when received 'b' will turn OFF relay1.

firstly create two buttons UI by Nextion Editor PC software:
   
   

here is firmware BIN file, you can download to KC868-A4 ESP32 directly to use:

.zip   nextion_KC868-A4.ino.nodemcu-32s.zip (Size: 102.25 KB / Downloads: 530)
here are source code:

Code:
String indata="";
String val="";

const int Relay1 = 2;
const int Relay2 = 15;
const int Relay3 = 5;
const int Relay4 = 4;

void setup() {
  pinMode(Relay1,OUTPUT);   //Relay1 IO2
  pinMode(Relay2,OUTPUT);  //Relay2 IO15
  pinMode(Relay3,OUTPUT);   //Relay3 IO2
  pinMode(Relay4,OUTPUT);   //Relay4 IO2
  Serial1.begin(9600,SERIAL_8N1,23,21);
  Serial.begin(9600);
}

void loop() {
  while(Serial1.available()>0)
  {
    indata+=char(Serial1.read());
    delay(2);
    if(Serial1.available()<=0)
     {
        Serial.println(indata);
     }
  } 
  if(indata.length()>0)
  {
     val=indata;  
     if(val=="a")  
       {
         digitalWrite(Relay1,HIGH);
         Serial.println("Relay1-ON OK!");
       }
     else if(val=="b")
      {
         digitalWrite(Relay1,LOW);
         Serial.println("Relay1-OFF OK!");
      }
  }
  indata="";

This demo source code, you just replace with your 10 phone numbers, then will send one SMS to 10 mobile phone, you can also send to many many mobile phone number in loop() function.
   
   
// make sure set your Serial2 pins in your "HardwareSerial.cpp" for ESP32 as follows:
//#define RX2  15
//#define TX2  13

   

Code:
//code use for KC868-A8S board

int data;
String message;
unsigned long int last;

void setup()
{

  Tasmota Configuration file or Precompiled firmware for KC868-A8S
Posted by: pacitzu - 09-20-2022, 10:45 AM - Forum: KC868-A8S - Replies (11)

is there a configuration file or pre-compiled firmware for the KC868-A8S board?

I found this guide for the KC868-A8 board https://www.kincony.com/forum/showthread.php?tid=1128

but I have not found any guide to be able to use the KC868-A8S board with Tasmota.

Ok the two boards KC868-A8 and KC868-A8S are similar but there are some differences:
for example how can I configure the Rs485 with Tasmota.

Thank you
