Devices: Arduino board, Gas sensors (co2, co, 03, h2, air quality), resistor (100k-470k), Gas Sensor Breakout Board

Result:

i think the Gas sensors are not really sensitive. maybe the problem is the situation is not good enough for the sensor. not much changes from the output data. i think the wiring is correct. Emmmm~ not sure what’s wrong. Maybe i should go to rubbish storeroom or cloaca to test the sensor. and the CO2 sensor need 6v power, others require 5v. (*_*!!!)

Tutorial Alcohol Gas Sensor MQ-3 + Arduino: (no in English *_*)
