Capteur CO2 Compatible avec Arduino - RobotShop

Le Capteur de CO2 compatible Arduino est le premier capteur de CO2 en source libre physique (OSHW). La tension de sortie du module diminue à mesure que la concentration de CO2 augmente. Le potentiomètre intégré est conçu pour régler le seuil de tension. Aussi longtemps que la concentration en CO2 est trop élevée (tension inférieure au seuil), un signal numérique (ON/OFF) est émis. Il dispose …

CO2 Monitor - Arduino Project Hub

And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a function of relative humidity and temperature is equal for CO2 and hydrogen. I do not have any calibration gasses, so I cannot check whether this is true or not. As long …

Arduino CO Monitor Using MQ-7 Sensor : 8 Steps (with ...

But here's the problem: Arduino can't provide enough power to run this sensor from its pins - sensor's heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won't work. So we must use some kind of current amplifier that takes small input current to control large output current.
