Example 1: Basic Temperature Control with Alarm

In this example, we'll demonstrate how to use the XH-W3001 to control a relay output based on a temperature setpoint. We'll also configure the buzzer to sound an alarm when the temperature exceeds the setpoint.

Code (Arduino)
```c++
const int relayPin = 2;  // Relay output pin
const int buzzPin = 3;  // Buzzer output pin
const int setButtonPin = 4;  // Set button pin
const int upButtonPin = 5;  // Up button pin
const int downButtonPin = 6;  // Down button pin

int temperatureSetpoint = 30;  // Initial temperature setpoint (C)

void setup() {
  pinMode(relayPin, OUTPUT);
  pinMode(buzzPin, OUTPUT);
  pinMode(setButtonPin, INPUT);
  pinMode(upButtonPin, INPUT);
  pinMode(downButtonPin, INPUT);
}

void loop() {
  int temperature = readTemperature();  // Read temperature from XH-W3001
  if (temperature > temperatureSetpoint) {
    digitalWrite(relayPin, HIGH);  // Turn on relay output
    digitalWrite(buzzPin, HIGH);  // Sound alarm
  } else {
    digitalWrite(relayPin, LOW);  // Turn off relay output
    digitalWrite(buzzPin, LOW);  // Silence alarm
  }

// Adjust temperature setpoint using buttons
  if (digitalRead(setButtonPin) == HIGH) {
    temperatureSetpoint = readTemperature();
  }
  if (digitalRead(upButtonPin) == HIGH) {
    temperatureSetpoint += 1;
  }
  if (digitalRead(downButtonPin) == HIGH) {
    temperatureSetpoint -= 1;
  }
}

int readTemperature() {
  // Read temperature from XH-W3001 using analog input or I2C interface
  // (implementation depends on the specific interface used)
  return analogRead(A0)  0.1;  // Convert analog value to temperature (C)
}
```
Example 2: Temperature Monitoring with LCD Display

In this example, we'll demonstrate how to use the XH-W3001 to monitor temperature and display it on an LCD display.

Code (Arduino)
```c++
#include <LiquidCrystal.h>

const int lcdRS = 12;  // LCD RS pin
const int lcdEN = 11;  // LCD EN pin
const int lcdD4 = 5;  // LCD D4 pin
const int lcdD5 = 4;  // LCD D5 pin
const int lcdD6 = 3;  // LCD D6 pin
const int lcdD7 = 2;  // LCD D7 pin

LiquidCrystal_I2C lcd(lcdRS, lcdEN, lcdD4, lcdD5, lcdD6, lcdD7);

void setup() {
  lcd.begin(20, 4);  // Initialize LCD display
}

void loop() {
  int temperature = readTemperature();  // Read temperature from XH-W3001
  lcd.setCursor(0, 0);
  lcd.print("Temperature: ");
  lcd.print(temperature);
  lcd.print(" C");
  delay(1000);  // Update display every second
}

int readTemperature() {
  // Read temperature from XH-W3001 using analog input or I2C interface
  // (implementation depends on the specific interface used)
  return analogRead(A0)  0.1;  // Convert analog value to temperature (C)
}
```
Note: The examples provided are simplified and may require additional error handling, calibration, and configuration depending on the specific application and hardware used.
