Étude de la fermentation et production de CO2 avec Arduino ...

+

Note : le signal analogique produit par le capteur de CO 2 est inversement proportionnel au taux de CO 2. Afin d''obtenir des données proportionnelles, nous inversons la tendance en posant valco2 = 1024 analogRead(co2) (le signal analogique lu par Arduino est une tension comprise entre 0 et 5 Volts et convertie pour correspondre à un entier compris dans l''interval [0 1023]).

MQ4 Methane Sensor Circuit Built with an Arduino

MQ4 Methane Sensor Circuit Built with an Arduino

+

The more methane it detects, the greater the analog voltage it will output. Conversely, the less CO it detects, the less analog voltage it will output. If the analog voltage reaches a certain threshold, it will send the digital pin DOUT high. Once this DOUT pin goes high, the arduino will detect this and will trigger the LED to turn on, signaling that the methane threshold has been reached and ...
