MQ-7 Kohlenmonoxidsensor als anschlussfertiges Modul für Arduino und Raspberry Pi Einfach zu nutzender Sensor zum Messen der Konzentration von Kohlenmonoxid (CO) in der Luft. Der MQ-7 misst eine Gaskonzentration von 300 bis 10000ppm und ist ideal zum Erkennen eines Gaslecks, als Gas-Alarm oder für sonstige Robotik- und Microcontroller-Projekte.
· This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable voltage regulator to drive this. The default voltage of …
· The MQ7 Gas Sensor module is useful for gas leakage detection. They are used in gas leakage detecting equipments in home and industry, are suitable for detecting of Carbon Monoxide. Due to its high sensitivity and response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.
· The sensor needs a load-resistor at the output to ground. It's value could be from 2kOhm to 47kOhm. The lower the value, the less sensitive. The higher the value, the less accurate for higher concentrations of gas. Der Wert den der Sensor ausgibt ist immer relativ. Man muss den kalibrieren. Dann kann man sagen Wert x ist die normal ...

The MQ7 is a simple-to-use Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer. Specification. Power supply needs: 5V; Interface type: Analog; Pin Definition: 1-Output 2-VCC 3-GND; High sensitivity to ...
Structure and configuration of MQ-7 gas sensor is shown as Fig. 3, sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel
· Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem. I followed the recommendation to use a 10KOhm resistor and soldered the MQ7 to the PCB. It doesn't matter which side and how around ...
Gas sensor MQ7 detects the presence of Carbon Monoxide (CO) in the air. The best results are given when alcohol is in liquid form, however, it still does an amazing job when measuring in gas form. It needs a bit of time to warm up in order to work correctly. • Detects: Carbon Monoxide (CO)• Dimensions: 32mm x 22mm x 27mm• Voltage: 5V• Digital(HIGH/LOW) and analog(0V-5V) output• With ...
· MQ-7 Kohlenmonoxidsensor Das MQ-7 Sensor Modul ist ein einfach zu betreibender Sensor, der die Kohlenmonoxid-Konzentration der Luft messen kann. Der Detektionsbereich des Sensors liegt zwischen 20 – 2000ppm. Dieser Sensor ist …
· MQ7 Carbon monoxide sensor can detect CO gas and export both digital (0/1) and analog signals to Arduino. The TTL pin will export low voltage when CO GAS is detected. The analog pin will export voltage that is correlated to CO Gas density. This project will use MQ7 sensor to detect CO Gas and export the gas density value to Arduino’s serial window. 2) Parts used in the project: 1 x Arduino ...
