DHT22 and Soil Moisture sensor program error

Projects Programming
1

Hey guys
I've been trying for a while to make my program for a DHT22 and soil moisture sensor work.
Both sensors worked on their own but I can't integrate them together- I don't know much about Arduino
At the moment I have powered both the sensors through the 5V pin, and connect the soil moisture to ground and A, and the temp sensor to D and ground.

My code keeps coming up with this:

error: expected unqualified-id before '{' token

{

^

exit status 1
expected unqualified-id before '{' token

Is there anything wrong with my code? and how do i fix it?

int val = 0; //value for storing moisture value
int soilPin = A0;//Declare a variable for the soil moisture sensor
int soilPower = 7;//Variable for Soil moisture Power

int tempPower = 11;

#define DHTPIN 11
#include "DHT.h"
#define DHTTYPE DHT22 // DHT 22 (AM2302)

DHT dht(DHTPIN, DHTTYPE);

void setup() {
Serial.begin(9600); // open serial over USB
dht.begin();
pinMode(soilPin, INPUT);
pinMode(tempPower, INPUT);
}

void loop() {

float h = dht.readHumidity();
float t = dht.readTemperature();

Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %\t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.print(" *C ");

}

{
Serial.print("Soil Moisture = ");
Serial.println(readSoil());
int readSoil();

val = analogRead(soilPin);//Read the SIG value form sensor
delay(100);
return val;//send current moisture value

delay(2000);

}

Please put your code in code tags. It's the </> button in the text editor.

The loop ends when you close the braces with } under the line Serial.print(*C);

This code

   {  
  Serial.print("Soil Moisture = ");    
  Serial.println(readSoil());
  int readSoil();
  
    val = analogRead(soilPin);//Read the SIG value form sensor
    delay(100);
    return val;//send current moisture value

  delay(2000);

 }

is orphaned. It is not part of any function hence your error message. Get rid of the curly braces in the middle of the loop function so it all becomes 1 function.
In saying that, most of the code in the curly braces at the bottom doesn't do anything so you can probably safely delete all of it after the last Serial.print() and up to the delay.
