MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

· Therefore we compare the current analog sensor value with a constant, in my case 1000. If the analog sensor is greater than 1000, gas is detected and we set the buzzer active for one second. After this one second we deactivate the active buzzer again. The following picture shows the output of the serial monitor with the program code in the next section. You see clearly, when I activate the ...

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

· Falls du einen anderen Sensor als den MQ-2 verwendest und dieser eine andere Spannung hat, muss der Aufbau natürlich angepasst werden. Nachdem der MCP3008 richtig angeschlossen ist, nutzen wir den Port 0 und verbinden ihn an RX0 des TTLs. Auf der gegenüberliegenden Seite befindet sich RX1, welches an den Analog Pin (A0) des MQ2 Sensors kommt. Außerdem wird an den TTL vom Raspberry Pi ...
