May 09, 2016· Since the heater of the sensor draws a lot of current and the sensor needs 5V to work properly, it is better if you use an external power supply that assures you a voltage input of 5V with enough current for the heater (The Arduino provided a little less than when tested).
May 06, 2016· The voltage that the sensor outputs changes accordingly to the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is the following: The greater the gas concentration, the greater the output voltage
The gas sensor then detects an increase in the volume of gas in the room/box, the gas sensor will tolerate an increase in gas volume up to 220 ppm, if the gas volume has exceeded this value (>220 ppm), then the gas sensor will send the value to the Arduino microcontroller board which then responds to the input by performing two actions at once.
