很好,我可以为您提供一些参考代码,但是在开始之前,我需要知道您使用的是哪种型号的LCD显示器和火焰传感器,以及希望如何将按键、蜂鸣器和SIM800C模块集成到程序中。此外,您需要确保您已经安装了与您的硬件兼容的库,例如LiquidCrystal_I2C库和SIM800L库。以下是一个简单的示例代码,仅供参考:
```C++
#include <SoftwareSerial.h>
#include <LiquidCrystal_I2C.h>
#define SIM800_RX_PIN 10
#define SIM800_TX_PIN 11
#define SIM800_BAUDRATE 9600
SoftwareSerial sim800(SIM800_RX_PIN, SIM800_TX_PIN);
#define FLAME_SENSOR_PIN A0
#define BUZZER_PIN 8
#define BUTTON_PIN 2
LiquidCrystal_I2C lcd(0x27, 16, 2); // I2C address, columns, rows
bool flame_detected = false;
void setup() {
Serial.begin(9600);
sim800.begin(SIM800_BAUDRATE);
lcd.init(); // initialize the lcd
lcd.backlight(); // turn on backlight
lcd.setCursor(0, 0);
lcd.print("Flame Detector");
lcd.setCursor(0, 1);
lcd.print("Initializing...");
pinMode(FLAME_SENSOR_PIN, INPUT);
pinMode(BUZZER_PIN, OUTPUT);
pinMode(BUTTON_PIN, INPUT_PULLUP);
}
void loop() {
if (digitalRead(BUTTON_PIN) == LOW) {
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Sending SMS...");
delay(1000);
String message = "Flame detected!";
sim800.println("AT+CMGF=1"); // configure SIM800C to send SMS in text mode
delay(1000);
sim800.println("AT+CMGS=\"+1234567890\""); // replace with recipient's phone number
delay(1000);
sim800.println(message);
delay(1000);
sim800.write(0x1A); // end of message
delay(1000);
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("SMS Sent!");
delay(1000);
}
int sensor_value = analogRead(FLAME_SENSOR_PIN);
if (sensor_value > 500) { // adjust threshold
if (!flame_detected) {
flame_detected = true;
lcd.clear();
lcd.setCursor(0, 0);
lcd.print("Flame Detected!");
digitalWrite(BUZZER_PIN, HIGH);
}
} else {
if (flame_detected) {
flame_detected = false;
lcd.clear();
lcd.setCursor(0, 0);
lcd.print(" ");
digitalWrite(BUZZER_PIN, LOW);
}
}
}
```
请注意,此代码仅用于示例和参考目的,您需要根据您的硬件和需求进行适当的修改和调整。此外,请确保您已经正确连接您的硬件,并已正确设置您的SIM卡和SIM800C模块,以使其能够发送短信。
