MQ4 Methane Gas Sensor : Pinout, Interfacing with Arduino ...

Gas sensors are quite useful devices for controlling pollutants in the air. Similar is the MQ4 Methane Gas sensor. The MQ4 sensor is a compact gas sensor which is highly sensitive to methane gas and less prone to alcohol and other gases. This methane gas sensor provides an output signal according to the sensed concentration of CH4 in the surrounding or environment. This sensor is proved to be ...

7 thoughts on “ESP32: BME680 Environmental Sensor using Arduino IDE (Gas, Pressure, Humidity, Temperature)” Ulrich. July 28, 2020 at 5:17 am Hi, it seems that there is a conflict according description of SDA and SDO respectively MISO and MOSI in the table “BME680 Pinout” I think SDA must be MOSI and SDO must be MISO. Reply. Sara Santos. July 28, 2020 at 9:36 am Hi. Thanks for noticing ...

Luftqualitätssensor MQ-135 Kallibrieren

· Diese "500" sind Deine Referenz. Weicht der Wert ab (473/523) dann sagst Du dem Arduino "mach was". Es wird also nur verglichen. Willst Du richtig messen, dann brauchst Du eine richtige Referenz. Du brauchst also einen Raum, in dem Du verschiedene Werte simulieren kannst. Ich wollte damit mal einen Stadt-Gas Sensor bauen. Da der aber nur Vergleicht, habe ich es dann …

· Your experience with Methane Gas Sensor? Using Arduino. Sensors. frankhgw. August 6, 2021, 10:30am #1. Hello, I am looking at the MQ-4, I am wondering what the sensitivity is. I read the datasheet, "Detecting concentration: 200-10000ppm". But since I'm not familiar with it, it doesn't tell me much. If I am in a cow barn, will I reach 200ppm ? Or (sorry) on a badly ventilated toilet, do I reach ...

I Need Sensor that measures the pressure of propane gas in ...

· Hi .. i'm programer.. i will do android app to monitoring the gas tank level (propane gas). So i'm looking for sensor to do this function. either by measuring the pressure of the output gas or maybe using sensor to measuring the gas flow (assuming we know the full capacity of the gas inside the gas tank ). i don't know much about gases , So i don't know what the solution.
