Introduction The Grove Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect H2, LPG, CH4, CO, Alcohol, Smoke, Propane. Based on its fast response time. Measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer. 2 2. Features Wide detecting scope Stable and long life Fast response and High …

Connect the Grove Gas Sensor(MQ2) to A0 port as shown in the above picture. Gas Detection : Basic Example. In this example, the sensor is connected to A0 pin. The voltage read from the sensor is displayed. This value can be used as a threshold to detect any increase/decrease in gas concentration.

Each Grove Gas Sensor Kit consists of one gas sensor base and four detectors, including MQ2, MQ3, MQ5, and MQ9. Below is a contrast table of them. You can switch the detector on the base according to specific target gases.

If you search "gas sensor" on , you can find a lot of gas sensor. We know that the air component is diverse, and a certain gas sensor can detect one or more air components, so we designed a series of gas sensor. There are about 10 kind of gas sensor for sale. They have similar name, it''s likely to cause confusion. Hope that through the following presentation, we can help you ...

The Grove Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect LPG, ibutane, methane, alcohol, Hydrogen, smoke and so on. Based on its fast response time. measurements can be taken as soon as possible. …

Grove Oxygen Sensor(ME2O2Ф20) is a kind of analogue gas sensor to test the oxygen concentration in air, which is based on the principle of the electrochemical cell to the original work. You can know clearly the current oxygen concentration when you output voltage values proportional to the concentration of oxygen and refer to the oxygen concentration linear characteristic graph.

Please understand that this sensor’s voltage range is nonlinear. It also depends on the load resistor value (POT). It is better to use the analog value range 0 1023 to set gas detection threshold. If you intened to measure the concentration, follow the direction given in the Wiki.

The Grove Gas Sensor (MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer.

It can be more effective if we measure these gases from a distant safer place with wireless communication devices and components, so that a monitoring system is …
