sensors - MG811 CO2 wiring help Arduino - Stack Overflow

20/03/2014· 1 Answer1. Active Oldest Votes. 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 ...

MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

Once this DOUT pin goes high, the arduino will detect this and will trigger the LED to turn on, signaling that the CO threshold has been reached and is now over the limit. How you can change this threshold level is by adjusting the potentiometer to either raise or lower the level. MQ-7 Carbon Monoxide Sensor Circuit Schematic. The carbon monoxide sensor circuit we will build with an MQ-7 sensor integrated …
