There are 2 repositories under mq4 topic.
We present a unified library for MQ sensors, this library allows to read MQ signals easily from Arduino, Genuino, ESP8266, ESP-32 boards whose references are MQ2, MQ3, MQ4, MQ5, MQ6, MQ7, MQ8, MQ9, MQ131, MQ135, MQ136, MQ303A, MQ309A.
This is your one-stop-shop to view actionable market data. This indicator is a Dashboard that displays market information and analytical data on the markets, directly on the broker platform. No need to switch between charts or websites looking at dozens of indicators. When used combined as a strategy the user gets real-time analysis of market conditions across many markets and this provides a better overall picture of true market conditions.
Air Analyzer, Using Almost All Kinds of MQ Sensors
Library to interface MQ-4 gas sensor
Metatrader tools to better understand moving averages variations
Arduino Atmega 2560 kullanarak yapılmış DHT22, MQ4, ESP8266 ve O2 sensörleri kullanarak ortamdaki gaz, ısı, nem ve oksijen değerlerini alan ve oksijen giriş/çıkışı olmayan kapalı ve boş bir ortamda bulunan hareketsiz bir insanın, hayatta kalma süresinin hesaplanmasını gerçekleştiren proje.
This repo demonstrates Arduino Uno compatibility with multiple sensors. Modular code structure allows easy expansion. Ideal for Arduino enthusiasts and environmental monitoring projects.
Firmware for my board named ESP8266MCU11, based on ESP8266 microcontroller. This device use a MQ-4 gas sensor and use MQTT protocol to send data to OpenHAB Smart Home Automation System.
