best board with 8 inputs

Posted by: ndev - 12-08-2023, 01:36 PM - Forum: Suggestions and feedback on KinCony's products - Replies (9)

	Hi, I looked into your website and I like all your board. Great ! You have so many board, it is difficult to find the correct one. I have a project for which I need at least 4 boards with 8 inputs and some relays (no more than 6 for each). I will use esphome with Ethernet. What could be the best board for me ? KC868-A8 KC868-A8S KC868-A8S V2 .... Thanks,

Board for window contact sensors

Posted by: threadstone - 12-07-2023, 08:53 PM - Forum: Development - Replies (15)

Dear Kincony-Team,

I'm currently looking for a suitable circuit board to realize a new project. At my search I found your website and some boards that could be the right one (for example the KC868-AI) but I’m not sure which one is the right one. Can you possibly tell me if the KC868-AI is the right one respectively which of your boards would be suitable?

I have 13 windows in my house and every window has an sensor for the status (open, closed and tilted). I want to integrate these sensors in my already existing Home Assistant installation. I think the integration via ESP could be one solution.
Here the information about the sensors:

7-wire cable
- 2 wires for the sabotage loop / sabotage line
- 2 wires for the signaling contact (generally open/closed)
- 3 wires for the open/tilted state (common "ground")

According to the instructions, there are also the following technical data:

General:
- Switch voltage max. 48V DC
- Contact resistance max. 150mOhm
Surveillance:
- Switching current max. 0.5A
- Transport current max. 1.0A
- Switch performance max. 10W pure ohmic load
or for the tilt status query:
- Switching current max. 0.25A
- Transport current max. 1.2A
- Switch performance max. 3W pure ohmic load

Attached you can find an extrude of the installation instructions.

It would be nice if you could tell me if the KC868-AI is suitable. If it is not, which of your boards would be suitable? Is there eventually already a program / yaml for ESP or Home Assistant is existing?

Thank you in advance.

TDS Sensor

Posted by: suliman0007 - 12-07-2023, 03:42 PM - Forum: KC868-A8 - Replies (3)

Hello
I Want conncetd TDS Sensor
Model SEN0244 to KC868-A8
I tride this example :
#define TdsSensorPin 34
#define VREF 3.3 // analog reference voltage(Volt) of the ADC
#define SCOUNT 30 // sum of sample point

int analogBuffer[SCOUNT]; // store the analog value in the array, read from ADC
int analogBufferTemp[SCOUNT];
int analogBufferIndex = 0;
int copyIndex = 0;

float averageVoltage = 0;
float tdsValue = 0;
float temperature = 23; // current temperature for compensation

// median filtering algorithm
int getMedianNum(int bArray[], int iFilterLen){
int bTab[iFilterLen];
for (byte i = 0; i<iFilterLen; i++)
bTab[i] = bArray[i];
int i, j, bTemp;
for (j = 0; j < iFilterLen - 1; j++) {
for (i = 0; i < iFilterLen - j - 1; i++) {
if (bTab[i] > bTab[i + 1]) {
bTemp = bTab[i];
bTab[i] = bTab[i + 1];
bTab[i + 1] = bTemp;
}
}
}
if ((iFilterLen & 1) > 0){
bTemp = bTab[(iFilterLen - 1) / 2];
}
else {
bTemp = (bTab[iFilterLen / 2] + bTab[iFilterLen / 2 - 1]) / 2;
}
return bTemp;
}

void setup(){
Serial.begin(115200);
pinMode(TdsSensorPin,INPUT);
}

void loop(){
static unsigned long analogSampleTimepoint = millis();
if(millis()-analogSampleTimepoint > 40U){ //every 40 milliseconds,read the analog value from the ADC
analogSampleTimepoint = millis();
analogBuffer[analogBufferIndex] = analogRead(TdsSensorPin); //read the analog value and store into the buffer
analogBufferIndex++;
if(analogBufferIndex == SCOUNT){
analogBufferIndex = 0;
}
}

static unsigned long printTimepoint = millis();
if(millis()-printTimepoint > 800U){
printTimepoint = millis();
for(copyIndex=0; copyIndex<SCOUNT; copyIndex++){
analogBufferTemp[copyIndex] = analogBuffer[copyIndex];

// read the analog value more stable by the median filtering algorithm, and convert to voltage value
averageVoltage = getMedianNum(analogBufferTemp,SCOUNT) * (float)VREF / 1024.0;

//temperature compensation formula: fFinalResult(25^C) = fFinalResult(current)/(1.0+0.02*(fTP-25.0));
float compensationCoefficient = 1.0+0.02*(temperature-25.0);
//temperature compensation
float compensationVoltage=averageVoltage/compensationCoefficient;

//convert voltage value to tds value
tdsValue=(133.42*compensationVoltage*compensationVoltage*compensationVoltage - 255.86*compensationVoltage*compensationVoltage + 857.39*compensationVoltage)*0.5;

//Serial.print("voltage:");
//Serial.print(averageVoltage,2);
//Serial.print("V ");
Serial.print("TDS Value:");
Serial.print(tdsValue,0);
Serial.println("ppm");
}
}
}

the result ppm 0
