Material : MQ-135 / Kabel / Arduino (Materialbeschaffung ) Der MQ-135 Sensor ist ein Modul, welches die Konzentration verschiedener Schadstoffe in der Luft erfasst. Der Sensor gibt die erfassten Schadstoffwerte als analogen Wert aus. Diese können im Anschluss im seriellen Monitor ausgegeben oder
· The MQ-135 gas sensor has an inbuilt variable resistor (sense resistor) that changes its resistance value according to the concentration of gas. If the gas concentration is high, the resistance decreases, and if the gas concentration is low, the resistance increases. The MQ-135 gas sensor basically needs only one key component as the external component – just a load resistor. The load resistor serves to adjust the sensor’s …
