Raspberry Pi Gas Sensor (MQ-X) konfigurieren und auslesen

· Konfiguration des Raspberry Pi Gas Sensor – Vorbereitung Die Angaben der Konzentration eines Gases werden in PPM (parts per million) angegeben. Eine Schwierigkeit des MQ-2 ist nun, dass ein einziger analoger Wert ausgegeben wird, mit welchem der Gasgehalt in der Luft für die verschiedenen unterstützten Gase berechnet werden muss.

Interfacing MQ-2 Gas Sensor with evive - STEMpedia

MQ2 gas sensor is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. Note: The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration.

Interfacing MQ-2 Gas Sensor with evive - STEMpedia

The MQ2 Gas sensor has a built-in variable resistor that changes its value according to the concentration of gas. If the concentration is High, the resistance decreases, if the concentration is low, the resistance increases. Besides the built-in resistor, it is necessary to include load resistor, Load resistor serve to adjust sensor sensitivity and accuracy, it’s value can range from 2k ohm ...
