MQ 2 Sensor Fiche technique

Me Gas Sensor(MQ2) – Open-source Arduino Robot Building ...

Detection principle: MQ-2 type of smoke sensor adopts stannic oxide as the semiconductor gas sensitive material which is the surface ionic N-type semiconductor. When the temperature is in the range of 200~300℃, the stannic oxide adsorbs the oxygen in the air to form into negative oxygen ions, so that the electron density of the semiconductor is decreased and its resistance is increased. When ...

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 ...

MQ2 Gas Sensor Tutorial for Arduino, ESP8266 and ESP32

· The standard test conditions for the MQ sensors is 5V+-, so powering it with will could give you unreliable readings. If you need precise output, you should consider using a 5V power source, regulate it down to for your MCU (this is included in most devkits) and keep 5V for the sensor. Then use a voltage divider to convert the 0-5V signal to If you only need a digital ...
