20210402· The “MQ” series of sensors are a bunch of cheap sensors for detecting CO, CO2, CH4, Alcohol, Propane, Butane, LPG etc. You can use these sensors to build your own Smoke Sensor Application. Check out this SMOKE DETECTOR ALARM CIRCUIT without using Arduino. Alcohol Sensor. As the name suggests, an Alcohol Sensor detects alcohol. Usually, alcohol sensors are …

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.

20210506· dc42 September 15, 2011, 10:30pm 5. As has already been said, you need to drive the CTRL pin from an Arduino output. A high on this pin turns the heater on, which is necessary for the CO2 sensor to work. I''d ignore the ALM output and connect TP1 to an Arduino analog input instead. That will give you a readout of the CO2 level, rather than just ...
