Configure and read out the Raspberry Pi gas sensor (MQ-X)
Sensors are necessary to detect the components of the air. These are used e.g. in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi
How to Use the MQ-7 Carbon Monoxide Sensor
From the log-log plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then only RS varies for every gas. RS is the sensor resistance and forms a voltage divider with the resistor R2 (see schematic diagram above).

Introduction. TB6600 arduino Stepper Motor Driver is an easy-to-use professional stepper motor driver, which could control a two-phase stepping motor is compatible with Arduino and other microcontrollers that can output a 5V digital pulse signal.
The output signal is filtered by hardware and has low overall jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), making the sensor simple and convenient.
