Temperature and Humidity sensor values

[account789]

Hi,

I'm a beginner in Arduino. For my first project, I decided to try this one:

vaneslin/PlantManager/blob/master/README.md

However, when I read the data in my Serial monitor in Arduino, I get the following values (attached below).
Is this normal when the code is supposed to return degrees in Celsius? Also, when I pour water over the sensors, values don't change...

Is there a problem with the code or the way I placed the wires in my circuit? Or are the components not working properly due to their bad quality?

#include<math.h>
#define THERMISTOR A0  //thermistor @ A0
#define MOISTURE A1  //moisture sensor @ A1 
   
double getTemperature(int thermistorReading) {
 /*** returns calculated Celcius temperature ***/ 
 //Steinhard-Hart equation from source: https://www.ametherm.com/thermistor/ntc-thermistors-steinhart-and-hart-equation
 double temp = log(10000.0 * (( 1023.0 / thermistorReading - 1))); 
 temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * temp * temp )) * temp );
 
 //subtract 273.15 to convert from Kelvin to Celcius
 temp = temp - 273.15;        
 
 //calibrated with cold and hot temperatures, constant gap of ~ 6 degrees
 temp += 6;
 return temp;
}

double getMoisture(int moistureReading) {
  /*** returns moisture %, where moistureReading ranges from 0 (underwater) to 1023 (bone dry) ***/
  double moisture = 100.0 - (100.0 * (moistureReading / 1023.0));
  return moisture;
}
 
void setup(void) {
  Serial.begin(9600);
}
 
void loop(void) {
  Serial.println(int(getMoisture(analogRead(MOISTURE)))); 
  Serial.println(int(getTemperature(analogRead(THERMISTOR))));
  delay(1000);
}

Thanks

read the bottom half of my signature. post your code, in code tags. if you don't help us help you, we don't help you.

This sketch uses A1 for the soil moisture: github.com/vaneslin/PlantManager/blob/master/Arduino_Code.ino.
You use A3.

The pins for the soil moisture module are:

• VCC
• GND
• Digital Output
• Analog Output

You did not connect a wire to the Analog Output.

Thanks for the large photo of your project, otherwise I could not have spotted these problems.
