Introduction
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.
Context
Hardware
- ESP32 board
- MQ-5 sensor, detecting SnO2
- SG90 servomechanism
- microusb - usb A cable
- dupont cables
Software
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;
Challenges
Figuring out a way to design the webpage to allow me to switch the servomechanism to “automated” or “manual” mode.
