Hi, I'm using mine Raspberry Pi 4 with Homeassistant as home automation.
Now I trying to make with mine Arduino UNO a weather station.
Every sensor is working, and I want to sent it with a ESP8266 module (wifi) to mine Raspberry.
But this doesn't work fine 
Now I'm trying to do it with connected the Arduino directly to the raspberry.
The raspberry can read the values from the serial monitor from mine Arduino.
But to use these values in home assistant I need to use the JSON style.
Now mine question, how can I change mine skatch so I see a JSON style output?
this is the sketch that I maked/found on many different websites 
#include </Users/tomjanssen/Documents/Arduino/sketch_compleet_With_Jason/OneWire.h>
#include </Users/tomjanssen/Documents/Arduino/sketch_compleet_With_Jason/DallasTemperature.h>
#include <ArduinoJson.h>
#define ONE_WIRE_BUS 5 // input temperatuur sensor
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
float Celcius=0; // t.b.v. de temperatuur sensor
float Fahrenheit=0; // t.b.v. de temperatuur sensor
int ldrPin = A1; // input pin t.b.v. de licht sensor
int ldrVal = 0; // Waarde van potmeter t.b.v. de licht sensor
const int sensorMin = 0; // regen sensor minimum
const int sensorMax = 1024; // regen sensor maximum
void setup(void)
{
Serial.begin(9600); // Stel de seriële monitor in
sensors.begin();
}
void loop(void)
{
sensors.requestTemperatures(); // temperatuur sensor
Celcius=sensors.getTempCByIndex(0); // temperatuur sensor
Fahrenheit=sensors.toFahrenheit(Celcius); // temperatuur sensor
Serial.print(" C "); // temperatuur sensor
Serial.print(Celcius); // temperatuur sensor
Serial.print(" F "); // temperatuur sensor
Serial.println(Fahrenheit); // temperatuur sensor
delay(100); //interval uitlezen waardes
ldrVal = analogRead(ldrPin); // Lees de analoge waarde van de LDR licht sensor
Serial.println(ldrVal); // Toon de waarde in de seriële monitor licht sensor
int sensorReading = analogRead(A0); // lees de regen sensor op analog A0:
// map the sensor range (four options):
// ex: 'long int map(long int, long int, long int, long int, long int)'
int range = map(sensorReading, sensorMin, sensorMax, 0, 3);
// range value:
switch (range) {
case 0: // Sensor getting wet
Serial.println("Stort regen");
break;
case 1: // Sensor getting wet
Serial.println("regen");
break;
case 2: // Sensor dry - To shut this up delete the " Serial.println("'t is droog"); " below.
Serial.println("'t is droog");
break;
}
delay(1); // delay between reads
}
I hope to hear from you.
Thanks you a lot!
