sensors - MG811 CO2 wiring help Arduino - Stack Overflow

· 2. GND -> negative. VCC -> positive (voltage/current depends on sensor) AOUT -> analogOut, goes to a analogInput if you want to read the sensor that way. Pay attention that arduino can read at max AREF volt, by default AREF = AVCC = VCC = 5V (please note, taht is vcc of arduino, not of the sensor) DOUT -> digitalOut, goes to a pin depending on ...

MG811 CO2 Kohlendioxid-Sensor: : Computer & …

Der MG811-Sensor misst die Konzentration von Kohlendioxid (CO2) in der Luft. Der Sensor reagiert stark auf CO2 und ist weniger sensibel gegenüber alkohol und CO. Er kann zur Überwachung der Luftqualität. Fermentierungsprozessen oder für In-Door Anwendungen benutzt werden. Die Ausgangsspannung sinkt bei steigender CO2-Konzentration.

Air Pollution Detector: a CO2 Level Using MG-811 : 4 Steps ...

In my project I have considered that the sensor needs an initialization period on a cold start of about 24-48 hours (when you get form the supplier) and about 5-20 min preheating period on each start (when cold), so on each start, I'm running a 30 min countdown time so both MG811 and the GSM (need 3 sec to connect to Network) can initialize successfully. Anyways, I have added an ON/OFF switch ...

Detektor oxidu uhličitého CO2 MG811 | Návody Drátek

Detektor oxidu uhličitého MG811 je zajímavým senzorem, který dokáže měřit takzvanou kvalitu vzduchu v místnosti díky měření koncentrace CO2. Podle různých studií by měla běžná vyvětraná místnost dosahovat hodnoty okolo 300-400 ppm. Pokud se ale překročí hranice například 1000 ppm, tak může docházet k únavě či nesoustředění. A právě v těchto případech ...
