This project aims to build a setup based on a servomechanism and a sensor MQ-5, with the purpose of opening a window in case the gas concentration rises above a desired value.

• ESP32 board
• MQ-4 sensor, detecting SnO2
• SG90 servomechanism
• microusb - usb A cable
• dupont cables

Code snippets

#include <WiFi.h>
#include <WebServer.h>
#include <ESP32Servo.h>
 
const char* ssid = "";
const char* password = "";
 
#define ANALOG_PIN 34  // Pinul conectat la AO al senzorului MQ-4
#define SERVO_PIN 13   // Pinul conectat la servomotor
 
int valoare_analogica = 0;
String nivelGaz = "";
String culoareNivel = "green";
bool servoActiv = false;
bool modAutomat = true;
int pragActivare = 800;  
 
Servo myservo;

Figuring out a way to design the webpage to allow me to switch the servomechanism to “automated” or “manual” mode.
