Pir sensor wiring for nodemcu esp32

Posted by: primeroz - 04-23-2023, 11:42 AM - Forum: DIY Project - Replies (9)

	I have a kincony pir sensor but still waiting to receive the A4 board so in the meantime I was thinking to wire it to a nodemcu esp32. Looking at the wiring diagram https://www.kincony.com/how-to-use-pir-sensor.html How should I wire the signal and COM to a nodemcu ? Is the signal just a 3.3v so I can just connect it to any gpio ? What about the COM ? Thanks

Life expectancy

Posted by: Philadam - 04-21-2023, 10:03 PM - Forum: KC868-A64 - Replies (3)

	I have a 44 year old DIY low voltage lighting system based on TTL circuits that is still going strong. I want to update this system to include smart monitoring. I have 2 questions. 1) What is the life expectancy of the kc868-a64? 2) What is the duration of your products before they go out if production?

	Do you support your products sold by other vendors on Aliexpress like Jijun Automatic Store?

Lora Range SX1278

Posted by: bsarevalo - 04-18-2023, 04:59 AM - Forum: KC868-A6 - Replies (8)

Hello everyone ! especially to Hificat... I am developing a project where we are using Lora SX1278 in the KC868-A6 module, according to the characteristics of the Lora the device has a range of 1 km - 5 km, the code used by the sender is the following :

Code:
#include "Arduino.h"

#include "PCF8574.h"

#include <RTClib.h>

#include <Wire.h>

#include <LoRa.h>

#include <SPI.h>

#include <WiFi.h>

#define ss 5

#define rst 21

#define dio0 2

void setup() {

  Serial.begin(115200);

  WiFi.mode(WIFI_STA);

  while (!Serial);

  Serial.println("LoRa Sender");

  LoRa.setPins(ss, rst, dio0);    //setup LoRa transceiver module

  while (!LoRa.begin(433E6))     //433E6 - Asia, 866E6 - Europe, 915E6 - North America

  {

    Serial.println(".");

    delay(500);

  }

  LoRa.setSyncWord(0xA5);

  Serial.println("LoRa Initializing OK!");

  Dwin_hmi.begin(115200);

  LoRa.setPins(ss, rst, dio0);

  pcf8574.pinMode(P0, OUTPUT);

  pcf8574.pinMode(P1, OUTPUT);

  pcf8574.pinMode(P2, OUTPUT);

  pcf8574.pinMode(P3, OUTPUT);

  pcf8574.pinMode(P4, OUTPUT);

  pcf8574.pinMode(P5, OUTPUT);

  Serial.print("Init pcf8574...");

  if (pcf8574.begin()){

    Serial.println("OK");

  }else{

    Serial.println("NO");

  }

  pcf8574.digitalWrite(P0, HIGH);

  pcf8574.digitalWrite(P1, HIGH);

  pcf8574.digitalWrite(P2, HIGH);

  pcf8574.digitalWrite(P3, HIGH);

  pcf8574.digitalWrite(P4, HIGH);

  pcf8574.digitalWrite(P5, HIGH);

}

void loop() {

  LoRa.beginPacket();   //Send LoRa packet to receiver

  LoRa.print("LP01");

  LoRa.endPacket();

  Serial.println("Sending packet LP0: 1 ");

}

And the code for the receiver is the following

Code:
#include "Arduino.h"

#include "PCF8574.h"

#include <RTClib.h>

#include <Wire.h>

#include <LoRa.h>

#include <SPI.h>

#include <MCP23017.h>

#define ss 5

#define rst 14

#define dio0 21

void setup() {

  Serial.begin(115200);

  Serial1.begin(9600,SERIAL_8N1,13,12);

  while (!Serial);

  Serial.println("LoRa Receiver");

  LoRa.setPins(ss, rst, dio0);    //setup LoRa transceiver module

  while (!LoRa.begin(433E6))     //433E6 - Asia, 866E6 - Europe, 915E6 - North America

  {

    Serial.println(".");

    delay(500);

  }

  LoRa.setSyncWord(0xA5);

  Serial.println("LoRa Initializing OK!");

}

void loop() {

  //Serial1.write(0x01);

  //delay(20);

  //Serial1.flush();

  //delay(15);

  int packetSize = LoRa.parsePacket();    // try to parse packet

  if (packetSize)

  {

    Serial.print("Received packet '");

    while (LoRa.available())              // read packet

    {

      String LoRaData = LoRa.readString();

      Serial.print(LoRaData);

      if (LoRaData == "LP01") {

        pcf8574.digitalWrite(P0, HIGH);

      }

      if (LoRaData == "LP00") {

        pcf8574.digitalWrite(P0, LOW);

      }

    }

    Serial.print("' with RSSI ");         // print RSSI of packet

    Serial.println(LoRa.packetRssi());

  }

}

I have soldered the antenna on the correct pin and have done some tests, the communication works fine up to 3 meters, but when I move the modules further than 3 meters the communication fails ... maybe you could help me a little, we require a range of more than 200 meters... can you help me and tell me if I'm making a mistake in programming or installing the hardware? Or if I need to buy another Lora module maybe...?
