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 library calculates the slopes of a wide variety of gas sensors, popular models such as [MQ-2, MQ-3, MQ-4, MQ-5, MQ-6, MQ-7, MQ-8, MQ-9, MQ131, MQ-135, MQ-136, MQ-137, MQ303A, MQ307A, MQ309A]. It also supports Geiger Counters for Radioactive analysis It integrates with Matplotlib for data visualization, facilitates Data Science apply.
