LPG Sensor with MQ-6 and Arduino | Microcontroller Tutorials

MQ-6 Gas Leak Detector. If you want to detect only the presence of LPG in the air, you only need to connect the AO pin to any analog pin of the Arduino UNO. Then you must determine the threshold value by placing the MQ-6 near a safe LPG source (like an unignited gas stove) and record the reading. Note that the MQ-6 needs at least 20 seconds to ...

Current consumption of gas sensor module - Arduino Forum

May 06, 2021 · Those sensors need 5volt ±0.1volt, and draw ~200mA. Some Arduinos can deliver that under the right conditions. USB supply is likely to fail at the "±0.1volt accuracy". And the onboard 5volt regulator could overheat if an external voltage of 9volt is used. That 200mA is used by the heater, so won't change when sensor data is read by the ...

Arduino – Emic 2 text-to-speech module triggered from ...

Apr 28, 2015 · The gas sensor detects the gas via the Arduino, then triggers the Emic 2 to issue a voice alert when the gas ppm value crosses a designated threshold. The Emic 2 module also has many customization parameters for the voice styles. The text to speech module will inspire some great ideas for projects, I think! So will the gas sensor.
